Reasoning steps: Purgatory and prayers for the dead

Verdicts: S17 · Purgatory and prayers for the dead. Shared notes and post-750 development: afterlife.

S17.1 (was afterlife/L2): Prayers for the dead

Step S17.1.1: Scripture

2 Macc 12:43–45 (canonical for Catholic and Orthodox, not Protestants); 2 Tim 1:16–18 (Onesiphorus, possibly dead). Scripture is thin on this.

Step S17.1.2: Patristic evidence

tertullian-aft-s2 (offerings c. 200), perpetua-aft-s1, cyril-of-jerusalem-aft-s1, augustine-aft-s1.

Step S17.1.3: Weighing decision

Reading A: prayer for the dead is ancient and universal. Reading B: it is a later innovation. A is chosen. It is attested c. 200 as an established custom, and is liturgical by c. 350.

• Confidence: High

Step S17.1.4: Source-proximity weighing

See the proximity tiers.

• Scripture (benchmark): Within the canon all four share, Scripture gives no instruction to pray for the dead and no prohibition; 2 Tim 1:16–18 is ambiguous. 2 Macc 12:43–45 is outside the shared canon; it is noted here, not scored. (Scripture confidence: low-medium)
• Key sources by tier: Tertullian (T2, w 0.8); Cyril of Jerusalem (T3, w 0.6); Augustine (T3, w 0.6). Proximity factor: 0.667 (mean tier weight of 3 key source(s)).
• Assessment: Earliest witness: T2 (Tertullian, c. 205; the Abercius inscription). It has no instruction in the shared canon. 2 Macc 12 counts for Catholic and Orthodox but is not in the shared canon. Verdict unchanged (it reports the date of the practice).

S17.2 (was afterlife/L3): Purification after death

Step S17.2.1: Scripture

1 Cor 3:12–15 (σωθήσεται … ὡς διὰ πυρός); Matt 12:32 (“nor in the age to come”).

Step S17.2.2: Patristic evidence

augustine-aft-s2 (temporary punishments after death), perpetua-aft-s1, gregory-of-nyssa-aft-s1 (healing fire), origen-aft-s2.

Step S17.2.3: Weighing decision

Reading A: a Latin purgatory (place, temporal punishment, indulgences) is patristic. Reading B: post-mortem purification or relief is widely assumed, without a defined doctrine. B is chosen. Augustine allows purification after death but hesitates over details. The Greek idea of healing fire is tied to restoration. The term purgatorium and its systematization are medieval (12th c.; Lyons 1274 not rechecked; Florence 1439 verified: souls ‘cleansed after death by cleansing pains’).

• Confidence: Medium–high (B)

Step S17.2.4: Source-proximity weighing

See the proximity tiers.

• Scripture (benchmark): 1 Cor 3:12–15 is a Day-of-judgment testing of ministers’ work ‘as through fire’, not a post-mortem penal process; Matt 12:32 is at most implicit. (Scripture confidence: medium)
• Key sources by tier: Augustine (T3, w 0.6); Perpetua (T2, w 0.8). Proximity factor: 0.7 (mean tier weight of 2 key source(s)).
• Assessment: The firmest witness is Augustine (T3). Perpetua (T2) is a vision about her unbaptized brother, not a doctrine. 1 Cor 3:12–15 is a Day-of-judgment testing of works. Verdict changed: ‘post-mortem purification assumed’ overstated the early evidence. It now reads as a T3 position anticipated in T2, without clear Scripture support, and confidence drops to medium.
