Study 2: Who Has Immortality? — Advanced Study

Immortality Vocabulary, Word Studies, and Evidence Classification

Evidence Tiers

This series uses a three-tier evidence classification to distinguish what Scripture says from what people claim it teaches:

  1. Explicit (E) — The text directly says this. You can point to a verse and quote it.
  2. Necessary Implication (N) — No single verse says this word-for-word, but it unavoidably follows from what the text does say. No interpretation is needed — every reader, regardless of theological position, must agree.
  3. Inference (I) — Someone claims the Bible teaches this, but no verse says it and no combination of verses forces it. Something must be added beyond what the text contains: a concept, a framework, or a choice between possible readings.

The hierarchy matters: Explicit > Necessary Implication > Inference. An inference cannot override what the text explicitly states.

Section A: The Greek Word for "Immortality" — Athanasia (G110)

  1. Athanasia appears only 3 times in the entire New Testament. Look up all three occurrences: 1 Timothy 6:16, 1 Corinthians 15:53, and 1 Corinthians 15:54. In each case, who possesses athanasia — God, humans presently, or humans at a future event?

  2. In 1 Timothy 6:16, the word monos ("only, alone") modifies who has athanasia. The same word monos appears in 1 Timothy 1:17 ("the only wise God") and John 17:3 ("the only true God"). In those cases, does monos carry a qualified or absolute sense? What does this tell you about "who only hath immortality"?

  3. In 1 Corinthians 15:53-54, the verb is enduo ("to put on, to clothe oneself with"). Paul uses the same verb in Romans 13:14 ("put on the Lord Jesus Christ"), Galatians 3:27 ("put on Christ"), and Colossians 3:10 ("put on the new man"). In every case, does enduo describe acquiring something one already has, or putting on something new?

Section B: Incorruptibility — Aphtharsia (G861) and Aphthartos (G862)

  1. Look up all 8 NT occurrences of aphtharsia (incorruptibility/immortality): Romans 2:7; 1 Corinthians 15:42, 50, 53, 54; Ephesians 6:24; 2 Timothy 1:10; Titus 2:7. In how many of these is aphtharsia described as a present human possession?

  2. Look up all 7 NT occurrences of aphthartos (incorruptible/immortal): Romans 1:23; 1 Corinthians 9:25; 15:52; 1 Timothy 1:17; 1 Peter 1:4, 23; 3:4. To whom or what is aphthartos applied in each case? Is it ever applied to the human soul?

  3. In Romans 1:23, aphthartos describes God and phthartos describes man — in the same verse. What interpretive move is required to maintain that humans possess an incorruptible component despite this explicit contrast?

Section C: Mortality — Thnetos (G2349) and Corruption — Phthora (G5356)

  1. Look up all 6 NT occurrences of thnetos (mortal): Romans 6:12; 8:11; 1 Corinthians 15:53, 54; 2 Corinthians 4:11; 5:4. In each passage, what is described as mortal — the body, the flesh, or the person?

  2. In 1 Corinthians 15:53, Paul writes "this mortal" (touto to thneton) — the word is used absolutely, without the noun "body." Compare this with Romans 6:12 where he writes "your mortal body" (to thneton soma). What is the significance of Paul using the absolute form in 1 Corinthians 15:53?

  3. Look up key occurrences of phthora (corruption/decay): 1 Corinthians 15:42, 50; Galatians 6:8; 2 Peter 1:4; 2:12. In Galatians 6:8, what is the alternative to "reaping corruption"? What does this suggest about what corruption means in contrast to everlasting life?

  4. Read 2 Peter 2:12. Peter compares false teachers to "natural brute beasts, made to be taken and destroyed," and says they "shall utterly perish in their own corruption (phthora)." How many destruction-related words does Peter use in this single verse? What does the comparison to animals suggest about the nature of their destruction?

Section D: The Conditional Structure of Eternal Life

  1. Read the following passages and note the condition stated in each: John 3:16, John 3:36, John 5:40, John 6:53, John 10:28, 1 John 5:11-12. What is the common condition across all six texts? What happens to those who do not meet it?

  2. Read Romans 6:23 and Galatians 6:8 side by side. Each presents two mutually exclusive outcomes. List both pairs of outcomes. In either text, is a third option (conscious existence without life/incorruption) mentioned?

  3. Read 2 Thessalonians 1:9. The wicked are "punished with everlasting destruction (olethros aionios)." The noun olethros means ruin or destruction. Does the text describe unending conscious existence, or unending destruction?

  4. Read John 5:26. The Father "hath life in himself" and "hath given to the Son to have life in himself." If God has life inherently ("in himself"), what does this suggest about whether humans have life inherently?

Section E: The Absence of "Immortal Soul"

  1. Search a concordance for the phrase "immortal soul." How many occurrences exist in the Old or New Testament?

  2. Read Ezekiel 18:4 and Matthew 10:28. The first says the soul (nephesh) that sins shall die. The second says God can destroy (apollymi) both soul (psyche) and body in gehenna. If the soul is inherently immortal, what must be done to the plain meaning of "die" and "destroy" in these verses?

  3. Read Psalm 49:7-9, 12, 15, 20. How does the psalmist describe the fate of "man that is in honour"? What comparison does he draw? What exception does he state?

Section F: Counter-Arguments and Competing Readings

  1. Some argue that "God only hath immortality" (1 Tim 6:16) means God alone has self-existent, underived immortality — leaving room for humans to have a derived form. Does the text make this distinction? What must be added to arrive at this reading?

  2. Some argue that thnetos ("mortal") in Paul applies only to the body, not to the soul or spirit, which is exempt from mortality. Examine 1 Corinthians 15:53 ("this mortal") and 2 Corinthians 5:4 ("mortality"). Does Paul name an immortal counterpart to the mortal body anywhere in his letters?

  3. Some argue that the conditional-life passages in John (3:16, 3:36, 6:53, etc.) refer to a present quality of spiritual life, not to future immortality. Read John 6:39-40, 44, 54 — does Jesus connect "eternal life" with the future resurrection? Can John's "life" concept be separated from Paul's "immortality" concept?

  4. Read Luke 20:37-38. Jesus says "He is not a God of the dead, but of the living: for all live unto him." Some read this as proving the patriarchs are presently conscious. But what is Jesus arguing for in v.37 — the resurrection, or a conscious intermediate state? What is the function of "all live unto him" in his argument?

Section G: Cross-Study Connections

  1. In Study 1, you examined nephesh (soul) and found that it can die (Ezek 18:4), be destroyed (Matt 10:28), and is applied to both animals and humans. How does the immortality word study in this study reinforce or challenge those findings?

  2. Read 1 Corinthians 15:21-22 and Romans 5:12, 17. How did death enter the human race? If death is the result of sin entering through Adam, was the human condition before the Fall the same as after?

  3. Read Acts 17:18, 32. What was the reaction of the Greek philosophers when Paul preached the resurrection? If Greek culture already accepted the immortality of the soul, why would the resurrection provoke mockery? What does this tell you about whether the apostolic message was about inherent immortality or resurrection?

Evidence Classification Exercise

Classify each claim below as Explicit (E), Necessary Implication (N), or Inference (I). For inferences, identify the subtype: - I-A: Evidence-extending — uses only the text's own words and concepts, systematized into a broader claim - I-B: Competing evidence — biblical texts on both sides; resolved by Scripture-interprets-Scripture - I-C: Compatible external — adds concepts the text doesn't contain but doesn't contradict it - I-D: Counter-evidence — requires overriding or redefining what the text explicitly says
