Appendix C: Glossary of Key Terms

Aiōn (αἰών)

A Greek noun meaning “age,” “era,” or “a long period of time.” In the New Testament, aiōn refers to a span or era of time—sometimes a very long one, sometimes a finite one. It does not automatically mean “eternity” in the way we use that word today, though it can carry that meaning in certain contexts. Understanding this word is crucial because it forms the root of aiōnios (see below), the adjective traditionally translated “eternal” in passages about punishment. (See Chapter 20 for a full linguistic study.)

Aiōnios (αἰώνιος)

The adjective form of aiōn. Traditionally translated “eternal” or “everlasting” in English Bibles, but its actual meaning is closer to “age-long,” “pertaining to an age,” or “of the age to come.” Multiple Greek lexicons confirm that aiōnios does not inherently carry the sense of “endless duration.” In the Greek Old Testament (the Septuagint), it describes things that clearly had an end—like the Levitical priesthood or Jonah’s three days in the whale. The critical debate centers on Matthew 25:46, where Jesus speaks of kolasis aiōnios (“age-long punishment” or “eternal punishment,” depending on the translation). The meaning of this term has enormous implications for whether postmortem punishment is endless or finite. R. Zachary Manis has also argued that aiōnios can denote a divine quality—“pertaining to God” or “of the age to come”—rather than temporal duration. (See Chapters 20 and 23A.)

Annihilationism

The belief that those who finally reject God will ultimately cease to exist rather than suffer conscious torment forever. In this view, the “second death” spoken of in Revelation is a real, permanent death—the end of the person’s existence. Annihilationism is closely related to conditional immortality (see below), though the two terms emphasize slightly different things: “conditional immortality” emphasizes that eternal life is a gift from God (not something humans naturally possess), while “annihilationism” emphasizes the outcome for those who do not receive that gift. Key evangelical proponents include Edward Fudge, John Stott, and Clark Pinnock. This book uses both terms, but the author prefers “conditional immortality” because it focuses on God’s gracious gift rather than on destruction. (See Chapters 8, 21, 23, and 31.)

Apokatastasis (ἀποκατάστασις)

A Greek word meaning “restoration of all things.” In theological usage, it refers to the belief—held by several early Church Fathers, most notably Origen and Gregory of Nyssa—that God will ultimately restore all of creation to Himself, including every human being and possibly even the devil. The term comes from Acts 3:21, where Peter speaks of the “restoration of all things” (apokatastasis pantōn). Apokatastasis was a significant stream of thought in the early church (four of the six major theological schools in the first five centuries taught some version of it), but it was later condemned in connection with certain extreme versions of Origen’s theology at the Second Council of Constantinople in 553 AD—though the precise scope of that condemnation remains debated. The author of this book does not hold to apokatastasis (because the author believes some will finally reject God), but the historical and theological evidence for it is treated fairly throughout. (See Chapters 14, 24, 25, and 30.)

Choice Model (of Hell)

A philosophical and theological model of hell most associated with C.S. Lewis and Jerry Walls. On this view, hell is fundamentally self-chosen: God does not send people to hell against their will; rather, people who end up in hell have chosen to be there by persistently rejecting God. As Lewis famously put it, “The doors of hell are locked on the inside.” The choice model avoids some of the moral problems of the traditional view (it does not portray God as arbitrarily tormenting people), but R. Zachary Manis argues it struggles to account for biblical themes of divine wrath, judgment, and the fear of the Lord. The divine presence model (see below) occupies a middle ground between the choice model and traditionalism. (See Chapters 22, 23, and 23A.)

Conditional Immortality

The belief that human beings are not inherently immortal. Immortality—the ability to live forever—is a gift that God gives to those who are saved through faith in Jesus Christ. Those who finally reject God are not sustained in existence forever but are ultimately destroyed (they cease to exist). This stands in contrast to the traditional view (eternal conscious torment), which assumes all human souls are inherently immortal and therefore must exist forever, either in heaven or in hell. The author of this book holds to conditional immortality combined with a postmortem opportunity for salvation. Key biblical texts include Matthew 10:28 (“destroy both soul and body in hell”), John 3:16 (“perish”), Romans 6:23 (“the wages of sin is death”), and Revelation 20:14 (“the second death”). The author argues that conditional immortality is fully compatible with substance dualism: the soul can survive death without being indestructible, because God sustains it. (See Chapters 8, 21, 23, and 31.)

Descensus ad Inferos

Latin for “the descent to those below” or “the descent into the underworld.” This phrase refers to the Christian belief that between His crucifixion and resurrection, Jesus Christ descended to the realm of the dead (Hades/Sheol). The descensus is affirmed in the Apostles’ Creed (“He descended into hell”—where “hell” translates the Latin inferos, meaning the underworld or realm of the dead, not the hell of final punishment). The theological question is why Christ descended: Was it merely to announce His victory? Or did He preach the gospel to the dead, offering them salvation? This book argues for the latter reading, based primarily on 1 Peter 3:18–4:6. The descensus was widely believed in the early church to have soteriological (salvation-related) significance. (See Chapters 11, 12, 13, 24, and 25.)

Divine Presence Model (of Hell)

A model of hell developed most rigorously by philosopher R. Zachary Manis in his book Sinners in the Presence of a Loving God. On this view, hell is not a place of God’s absence but rather the experience of being in God’s full, unshielded presence as an unrepentant sinner. God’s love is not withdrawn from the damned—rather, they cannot experience that love as love. Manis compares it to wax brought too close to a raging fire: the fire does not intend to melt the wax, but that is the inevitable result. The divine presence model sits between traditionalism (which portrays hell as externally imposed punishment) and the choice model (which portrays hell as entirely self-chosen). It accounts for both biblical themes of divine love and divine judgment. The author of this book adapts the divine presence model within a conditional immortality framework: God’s purifying presence burns away evil, and those who repent are saved, while those who refuse are ultimately consumed (annihilated). Manis himself acknowledges the model is “flexible enough” to accommodate postmortem conversion. (See Chapters 22, 23, and 23A.)

Emeth (אֱמֶת)

A Hebrew word meaning “faithfulness,” “truth,” or “fidelity.” In the Old Testament, emeth is one of God’s core attributes and is closely connected to hesed (lovingkindness) and tsedaka (justice/righteousness). Alexandre Kalomiros, in “The River of Fire,” argues that these three attributes form a unified picture of who God is—a God whose justice, love, and faithfulness all work together for the salvation of humanity, not against it. (See Chapter 23C.)

Eternal Conscious Torment (ECT)

The traditional view of hell held by most Western Christians since Augustine (fifth century AD). On this view, those who die without faith in Christ are consigned to hell, where they experience conscious suffering forever—without end and without any possibility of release or annihilation. ECT has been the dominant position in both Catholic and Protestant theology for most of Western church history, though it was not the only view in the early church. Key objections to ECT include: the apparent injustice of infinite punishment for finite sin, the difficulty of reconciling ECT with a God who “desires all people to be saved” (1 Timothy 2:4), and the fact that the biblical language of punishment (aiōnios) may not mean “eternal” in the modern sense. The author of this book rejects ECT in favor of conditional immortality with postmortem opportunity. (See Chapters 20, 21, 22, 23, and 31.)

Exclusivism / Restrictivism

The view that only those who explicitly hear and consciously accept the gospel of Jesus Christ during their earthly lifetime can be saved. Under strict exclusivism, everyone who dies without having made an explicit profession of faith in Christ—including infants, the unevangelized, the mentally disabled, and those who lived before Christ—is eternally lost. Exclusivism is held by theologians such as Ronald Nash, Wayne Grudem, and R.C. Sproul. The author argues that exclusivism creates the most severe form of the “soteriological problem of evil”—the theological crisis caused by the billions of people throughout history who never had any real access to the gospel. (See Chapters 1 and 4.)

Gehenna (γέεννα)

A Greek word derived from the Hebrew gē hinnōm (גֵּי הִנֹּם), meaning “Valley of Hinnom.” This was a real valley south of Jerusalem that had a dark history: it was the site where some Israelite kings practiced child sacrifice to the pagan god Molech (2 Kings 23:10; Jeremiah 7:31). By Jesus’ day, Gehenna had become a powerful metaphor for divine judgment and destruction. Jesus used “Gehenna” in His warnings about judgment (e.g., Matthew 5:22, 29–30; 10:28; Mark 9:43–48). Gehenna is not the same as Hades (which is the intermediate state). Many scholars believe Gehenna corresponds to the final state of judgment, closely related to the “Lake of Fire” in Revelation. It is important not to confuse Gehenna with Hades—they are different places in the biblical picture, and conflating them has caused significant theological confusion. (See Chapter 21.)

Hades (ᾅδης)

The Greek equivalent of the Hebrew Sheol. In the New Testament, Hades is the realm of the dead—a temporary holding place where the souls of the deceased wait between physical death and the final resurrection and judgment. Hades is emphatically not the same as the Lake of Fire or Gehenna. It is an intermediate state, not a final destination. The rich man in Jesus’ parable (Luke 16:19–31) is in Hades, not in the final hell. According to Revelation 20:13–14, Hades itself will be “thrown into the Lake of Fire” at the end of history—confirming that it is temporary. The distinction between Hades (temporary) and the Lake of Fire (final) is critically important for the postmortem opportunity thesis, because it means the unsaved dead in Hades have not yet received their final verdict. The intermediate state is a period during which God’s love and grace may still reach them. (See Chapters 9, 21, and 32.)

Hesed (חֶסֶד)

A Hebrew word often translated “lovingkindness,” “steadfast love,” “mercy,” or “covenant faithfulness.” Hesed is one of the most important words in the Old Testament for describing God’s character. It refers to God’s loyal, never-failing, covenant love for His people—a love that endures even when the people are unfaithful. Kalomiros argues that hesed, along with tsedaka and emeth, reveals a God whose fundamental nature is merciful love, not retributive wrath. The question this book raises is whether God’s hesed—His steadfast, relentless love—stops at the moment of physical death. We argue it does not. (See Chapters 2 and 23C.)

Inclusivism

The view that while Jesus Christ is the only Savior, it is possible for people to be saved through Christ’s work even if they have never explicitly heard the gospel. On this view, God may use general revelation (creation, conscience, the inner witness of the Holy Spirit) to draw people to Himself, and some who respond to the light they have may be saved through Christ’s atonement without knowing His name. Key proponents include Karl Rahner (who spoke of “anonymous Christians”), Clark Pinnock, and John Sanders. The author of this book sees inclusivism as partially correct but incomplete: postmortem opportunity provides the explicit encounter with Christ that inclusivism cannot guarantee during earthly life. The two views can be combined. (See Chapter 28.)

Intermediate State

The period between a person’s physical death and the future bodily resurrection and final judgment. During this time, the soul exists in a conscious but disembodied state—either in paradise/with Christ (for the saved) or in Hades (for the unsaved). The intermediate state is not the final state: it is a waiting period. The Bible portrays people in the intermediate state as conscious, aware, and capable of communication (see the rich man in Hades, the souls under the altar in Revelation 6:9–11, Moses and Elijah at the Transfiguration). This is theologically crucial for the postmortem opportunity thesis, because if the dead are conscious and capable of response during the intermediate state, then a genuine encounter with God is possible before the final judgment. (See Chapters 6, 9, 21, and 32.)

Kolasis (κόλασις) vs. Timōria (τιμωρία)

Two Greek words for punishment, with an important distinction. Kolasis means corrective or remedial punishment—punishment designed to improve or reform the one being punished. As William Barclay noted, kolasis “originally meant the pruning of trees to make them grow better,” and in all Greek secular literature it was never used for anything but remedial punishment. Timōria, by contrast, means retributive vengeance—punishment for the sake of satisfying justice, without any reformative purpose. Significantly, in Matthew 25:46—the most important New Testament verse about the duration of punishment—Jesus chose kolasis (the corrective term), not timōria (the retributive term). The Pharisees, when they wanted to express everlasting vindictive punishment, used the phrase aidios timōria (“eternal torture”)—but Jesus deliberately avoided that language. This suggests that the punishment Jesus described has a corrective, not merely punitive, purpose. (See Chapters 20 and 22.)

Lake of Fire

An image found in Revelation 19–20, representing the final state of judgment after the Great White Throne Judgment. The Lake of Fire is the destination of death, Hades, the devil, the beast, the false prophet, and those whose names are not found in the Book of Life (Revelation 20:14–15). The Lake of Fire is not the same as Hades (which is temporary and is itself thrown into the Lake of Fire). Revelation 14:10 says the torment of the wicked occurs “in the presence of the holy angels and in the presence of the Lamb”—suggesting the Lake of Fire is not a place away from God but is in fact God’s full, unshielded presence. The author of this book, drawing on the Eastern Orthodox “river of fire” tradition, the philosophical work of R. Zachary Manis, and the popular-level theology of Sharon Baker, argues that the Lake of Fire is God’s purifying presence—which saves those who repent and consumes those who refuse. (See Chapters 21, 23, 23A, 23B, and 23C.)

Natural Consequence Model (of Hell)

A philosophical model in which the suffering of hell is understood as the natural result of sin itself, rather than a punishment externally imposed by God. On this view, God does not actively torment anyone; rather, the pain of hell flows naturally from the person’s own sinful choices and their resulting alienation from the source of all goodness. R. Zachary Manis distinguishes his divine presence model from a pure natural consequence model: on Manis’s view, hell is between a natural consequence (the inevitable result of being a sinful creature in God’s full presence) and a retributive punishment (from the perspective of those experiencing it, it feels like divine wrath). (See Chapters 22 and 23A.)

Near-Death Experience (NDE)

A profound subjective experience reported by some individuals who have been clinically close to death or, in some cases, clinically dead and then resuscitated. Common features include: an out-of-body experience, movement through a tunnel, encountering a brilliant light, meeting deceased relatives, experiencing a “life review,” encountering a being of overwhelming love, and being told to return or choosing to return. NDEs have been documented across cultures, ages, and religious backgrounds by researchers such as Raymond Moody, Kenneth Ring, Pim van Lommel, Sam Parnia, Michael Sabom, Jeffrey Long, and Bruce Greyson. The theological significance of NDEs for this book is twofold: (1) they provide evidence for substance dualism and a conscious intermediate state, and (2) many NDE accounts describe an encounter with a divine being of light and love that is strikingly consistent with the postmortem encounter with God posited by this book. (See Chapter 5.)

Nephesh (נֶפֶשׁ)

A Hebrew word often translated “soul,” “life,” “self,” or “living being.” Nephesh has a wide range of meanings in the Old Testament. Some physicalist scholars argue that nephesh refers to the whole person (not a separable soul), and they use this to argue against substance dualism. However, several Old Testament passages use nephesh in ways that suggest a separable component: Genesis 35:18 says Rachel’s nephesh was “departing” as she died, and 1 Kings 17:21–22 describes Elijah praying for a dead child’s nephesh to “come into him again.” The author argues that while nephesh can refer to the whole person in many contexts, these passages show it can also refer to a separable, surviving soul. (See Chapter 6.)

Nonreductive Physicalism

A philosophical position holding that human beings are entirely physical (there is no immaterial soul), but that mental properties and consciousness “emerge” from physical processes in a way that is not simply reducible to brain chemistry. Proponents such as Nancey Murphy and Warren Brown argue this is more compatible with modern neuroscience than substance dualism. However, critics point out that nonreductive physicalism faces the “causal exclusion problem”—if all causes are physical, then mental properties do no real causal work, making the “nonreductive” part illusory. For the purposes of this book, the critical problem with any form of physicalism is that it eliminates the conscious intermediate state necessary for a postmortem encounter with God. (See Chapters 7 and 8.)

Olam (עוֹלָם)

The Hebrew equivalent of the Greek aiōn. Often translated “forever” or “everlasting” in English Bibles, but its core meaning is “a long time,” “an age,” or “a period whose end is hidden or unknown.” Like aiōnios, olam is applied in the Old Testament to things that clearly had an end: the “everlasting” Levitical priesthood (Numbers 25:13), the “everlasting” hills (Genesis 49:26, which collapse in Habakkuk 3:6), and Jonah being in the whale for an “olam” (Jonah 2:6)—which lasted three days. This demonstrates that the Hebrew term does not necessarily mean “without end.” (See Chapter 20.)

Physicalism

The philosophical view that human beings are entirely physical—there is no immaterial soul or spirit. On this view, consciousness, thoughts, emotions, and the sense of self are all products of brain activity and nothing more. When the brain dies, the person ceases to exist entirely (until God re-creates them at the resurrection, if one holds to a physicalist Christian view). Some evangelical conditionalists (influenced by Nancey Murphy and Joel Green) have adopted physicalism. The author of this book argues that physicalism is fatal to the postmortem opportunity thesis, because if there is no soul that survives death, there is no conscious person to encounter God between death and the resurrection. Veridical NDEs—where patients report accurate information they could not have known through normal means while their brains were non-functional—provide strong empirical evidence against physicalism. (See Chapters 5, 7, and 8.)

Pneuma (πνεῦμα)

A Greek word meaning “spirit,” “breath,” or “wind.” In the New Testament, pneuma is used in several ways: for the Holy Spirit, for the human spirit, for angels or demons, and for breath or wind. In the context of substance dualism, pneuma is significant because it refers to the immaterial aspect of a human being that survives death. Jesus committed His pneuma to the Father at death (Luke 23:46); Stephen asked Jesus to receive his pneuma (Acts 7:59); Hebrews 12:23 speaks of the “spirits (pneumata) of the righteous made perfect.” In 1 Peter 3:19, the “spirits in prison” (tois en phylakē pneumasin) may refer to human spirits in Hades—a key point in the debate about Christ’s descent to the dead. (See Chapters 6, 11, and 12.)

Postmortem Opportunity

The central thesis of this book. Postmortem opportunity is the belief that the chance to receive salvation through Jesus Christ does not end at the moment of physical death. Rather, God continues to love and pursue the unsaved after death, and all who die without having placed their faith in Christ will receive a genuine, personal encounter with God—most likely Jesus Christ Himself—at one or more of the following junctures: (a) during the dying process, (b) during the intermediate state in Hades, and/or (c) at or during the final judgment. This encounter is not a single fleeting moment but a deep, meaningful, and potentially extended experience. Those who respond in faith are saved; those who reject God even after this encounter face the consequences of their rejection. The author distinguishes this from universalism (which guarantees everyone will be saved) and from purgatory (which is for believers who need purification, not for the unsaved). The author also extends the offer to all the unsaved without exception—not just the unevangelized—because this is consistent with the character of a God who is love. (See every chapter of this book, especially Chapters 1, 2, 4, 10, 11, 31, and 33.)

Property Dualism

A philosophical position that holds there is only one kind of substance (physical matter), but that this substance can have two kinds of properties: physical properties (like mass and electrical charge) and mental properties (like consciousness and subjective experience). Property dualism is a middle ground between substance dualism and strict physicalism. However, it faces similar problems to physicalism for the purposes of this book: if the mind is a property of the brain (rather than a separate substance), then when the brain dies, the mind ceases to exist, and there is no conscious soul to survive death. The author holds to substance dualism, not property dualism, because only substance dualism can sustain a conscious intermediate state. (See Chapter 7.)

Pseudoevangelized

A term used by James Beilby and others to describe people who have technically “heard the gospel” but received a distorted, incomplete, or badly misrepresented version of it—one that may have actually pushed them further from God rather than drawing them closer. Examples include: people who grew up in abusive religious environments where God was presented as cruel and vindictive; people whose only exposure to Christianity was through hypocritical or harmful “Christians”; and people who heard a culturally mangled version of the gospel that bore little resemblance to the actual good news of Jesus Christ. The author argues that the pseudoevangelized deserve a genuine encounter with the real Christ after death, because what they rejected during their lives was not the real gospel. (See Chapters 1, 4, and 28.)

Psyche (ψυχή)

A Greek word meaning “soul,” “life,” or “self.” Psyche is the New Testament Greek equivalent of the Hebrew nephesh. It can refer to the whole person, to physical life, or to the immaterial soul that survives death. In Matthew 10:28, Jesus says, “Do not fear those who kill the body but cannot kill the psychē (soul); rather fear him who can destroy both psychē and body in Gehenna.” This passage draws a clear distinction between the body (which can be killed by humans) and the soul (which survives the body’s death and can only be destroyed by God). This is one of the strongest biblical texts supporting substance dualism. (See Chapter 6.)

Ruach (רוּחַ)

A Hebrew word meaning “spirit,” “breath,” or “wind”—the Hebrew equivalent of the Greek pneuma. In the Old Testament, ruach can refer to God’s Spirit, to the human spirit, to breath, or to wind. Ecclesiastes 12:7 says that at death, “the dust returns to the earth as it was, and the ruach returns to God who gave it”—distinguishing the body (dust) from the spirit (ruach) and indicating that the spirit survives the body’s death. (See Chapter 6.)

Second Death

A term found in Revelation 2:11; 20:6, 14; and 21:8, referring to the Lake of Fire. The “second death” is distinct from the first (physical) death and appears to describe the final fate of the unrepentant after the Great White Throne Judgment. Conditional immortalists understand the second death as genuine death—the permanent cessation of existence—while proponents of eternal conscious torment interpret it as an ongoing state of spiritual death (separation from God). The author of this book interprets the second death within the framework of the divine presence model: it is the annihilation that occurs when God’s purifying fire has removed all evil from a person who refused to repent, leaving nothing remaining. (See Chapters 21, 23, and 31.)

Sheol (שְׁאוֹל)

The Hebrew term for the realm of the dead in the Old Testament. Sheol is portrayed as a shadowy underworld where all the dead go—both the righteous and the wicked. In the earliest Old Testament texts, Sheol is described rather vaguely as a place of silence, darkness, and diminished existence. However, the Old Testament also affirms that God’s power extends even to Sheol (Psalm 139:8: “If I make my bed in Sheol, you are there”) and that God can redeem from Sheol (Psalm 49:15; Hosea 13:14). Over time, the understanding of the afterlife developed, and by the intertestamental period, Sheol was often understood as having separate compartments for the righteous and the wicked. In the New Testament, the Greek word Hades takes over this role. (See Chapters 17 and 21.)

Soul Sleep

The belief that the soul is unconscious between physical death and the future resurrection—that it exists in a state of dreamless “sleep” rather than conscious awareness. Soul sleep has been held by some Christians throughout history, including (arguably) Martin Luther and some Seventh-day Adventists. However, the author argues that the Bible consistently portrays the dead as conscious in the intermediate state: the rich man in Hades is aware and communicating (Luke 16), the souls under the altar cry out to God (Revelation 6:9–11), Moses and Elijah converse with Jesus at the Transfiguration (Luke 9:30–31), and Paul expects to be “with Christ” immediately after death (Philippians 1:23). The “sleep” language in the New Testament (e.g., 1 Thessalonians 4:13–14) is a metaphor for the body’s appearance in death, not a description of the soul’s condition. Soul sleep is incompatible with the postmortem opportunity thesis, since a sleeping soul cannot encounter God or make decisions. (See Chapters 6 and 9.)

Substance Dualism

The philosophical and theological view that a human being is composed of two distinct substances: a material body and an immaterial soul (or spirit). These are not merely two aspects or properties of one thing—they are two genuinely different kinds of reality that are united during earthly life but can be separated at death. The soul can exist and function apart from the body after death, retaining consciousness, identity, and the capacity for thought, emotion, and choice. Substance dualism is supported by both biblical evidence (Matthew 10:28; 2 Corinthians 5:1–8; Philippians 1:21–23; Revelation 6:9–11) and philosophical arguments (from personal identity, qualia, intentionality, the unity of consciousness, and mental causation). Key philosophical proponents include J.P. Moreland, Richard Swinburne, and Charles Taliaferro. Veridical NDEs provide empirical support for substance dualism by demonstrating that consciousness can function independently of brain activity. The author argues that substance dualism is essential for the postmortem opportunity thesis, because without a conscious soul that survives death, there is no one to encounter God between death and the resurrection. (See Chapters 5, 6, 7, and 8.)

Tartarus (Τάρταρος)

A Greek term used only once in the New Testament, in 2 Peter 2:4, where Peter says that God cast sinning angels into Tartarus and committed them to “chains of gloomy darkness” until the judgment. In Greek mythology, Tartarus was the deepest part of the underworld, reserved for the most wicked. Peter’s use of this term suggests a place of imprisonment for fallen angelic beings, distinct from both Hades (the general realm of the dead) and Gehenna/the Lake of Fire (the final place of judgment). Some interpreters of 1 Peter 3:19 argue that the “spirits in prison” to whom Christ preached are these same fallen angels in Tartarus, though the author of this book argues that the “spirits in prison” are more likely human dead in Hades. (See Chapters 11, 12, and 21.)

Theosis (θέωσις)

A Greek term meaning “deification” or “divinization.” In Eastern Orthodox theology, theosis refers to the process by which human beings become partakers of the divine nature (2 Peter 1:4)—not becoming God in essence, but becoming increasingly united with God and transformed by His grace. Theosis is the ultimate goal of salvation in Orthodox theology: humanity was created for union with God, and sin disrupted that union. Christ’s incarnation, death, and resurrection restore the possibility of theosis. The concept is relevant to this book because the Eastern Orthodox tradition understands the “fire” of God’s presence as the means by which theosis is accomplished—and for those who resist that transforming fire, the same divine energy is experienced as torment rather than glory. (See Chapter 23C.)

Tsedaka (צְדָקָה)

A Hebrew word usually translated “righteousness” or “justice.” Alexandre Kalomiros, in “The River of Fire,” argues that Western theology has misunderstood tsedaka by reading it through a Roman legal lens as “retributive justice”—a system of punishments balanced against crimes. In the Hebrew Bible, however, tsedaka is closer to “the divine energy which accomplishes humanity’s salvation.” It is parallel to hesed (mercy/lovingkindness) and emeth (faithfulness/truth). God’s justice is His saving, restoring love—not a competing attribute that must be “satisfied” before God can forgive. Isaac of Nineveh asked, “How can you call God just when you read the passage on the wage given to the workers?”—pointing out that God’s “justice” is radically generous, not coldly retributive. (See Chapter 23C.)

Universalism / Universal Reconciliation

The belief that God will ultimately save every human being (and in some versions, every sentient creature, including fallen angels). Universalists hold that God’s love is so powerful and His purposes so certain that no one will finally be lost. Key proponents include Thomas Talbott (The Inescapable Love of God), Robin Parry (The Evangelical Universalist), and George Hurd (The Triumph of Mercy). Among the early Church Fathers, Origen, Gregory of Nyssa, and Clement of Alexandria all held some form of universalism. The author of this book is not a universalist: while deeply sympathetic to the universalist conviction about God’s love, the author believes it is genuinely possible that some persons will persist in rejecting God even after the fullest possible revelation of His love and will ultimately be destroyed. However, the author believes universalism is a legitimate theological conversation partner and treats it respectfully throughout. Postmortem opportunity is compatible with universalism but does not require it. (See Chapters 14, 24, 25, and 30.)

Veridical NDE

A near-death experience that contains verified, accurate information the person could not have known through normal sensory means. Examples include patients who accurately report events happening in other rooms while they were clinically dead, or blind patients who “see” things during their NDE that are later confirmed to be accurate. Veridical NDEs are theologically significant because they provide empirical evidence that consciousness can function independently of the brain—which is precisely what substance dualism predicts and what physicalism cannot explain. Researchers who have documented veridical NDEs include Kenneth Ring and Sharon Cooper (cases of blind patients seeing during NDEs, documented in Mindsight), Michael Sabom, Sam Parnia (the AWARE studies), and Pim van Lommel. The author’s Th.D. dissertation research focuses on veridical NDEs as evidence for substance dualism and against the physicalist anthropology adopted by some in the conditional immortality movement. (See Chapters 5 and 8.)
