Old Testament
The tradition of the Jews is put forth with precision and clearness in 2 Maccabees. Judas, the commander of the forces of Israel,
making a gathering . . . sent twelve thousand drachmas of silver to Jerusalem for sacrifice to be offered for the sins of the dead, thinking well and religiously concerning the resurrection (For if he had not hoped that they that were slain should rise again, it would have seemed superfluous and vain to pray for the dead). And because he considered that they who had fallen asleep with godliness, had great grace laid up for them. It is therefore a holy and wholesome thought to pray for the dead, that they may be loosed from sins. (2 Maccabees 12:43-46)
At the time of the Maccabees the leaders of the people of God had no hesitation in asserting the efficacy of prayers offered for the dead, in order that those who had departed this life might find pardon for their sins and the hope of eternal resurrection.
New Testament
There are several passages in the New Testament that point to a process of purification after death. Thus, Jesus Christ declares (Matthew 12:32): "And whosoever shall speak a word against the Son of man, it shall be forgiven him: but he that shall speak against the Holy Ghost, it shall not be forgiven him, neither in this world, nor in the world to come." According to St. Isidore of Seville (Deord. creatur., c. xiv, n. 6) these words prove that in the next life "some sins will be forgiven and purged away by a certain purifying fire." St. Augustine also argues "that some sinners are not forgiven either in this world or in the next would not be truly said unless there were other [sinners] who, though not forgiven in this world, are forgiven in the world to come" (
City of God XXI.24). The same interpretation is given by Gregory the Great (Dial., IV, xxxix); St. Bede (commentary on this text); St. Bernard (Sermo lxvi in Cantic., n. 11) and other eminent theological writers.
A further argument is supplied by St. Paul in 1 Corinthians 3:11-15:
"For other foundation no man can lay, but that which is laid; which is Christ Jesus. Now if any man build upon this foundation, gold, silver, precious stones, wood, hay stubble: Every man's work shall be manifest; for the day of the Lord shall declare it, because it shall be revealed in fire; and the fire shall try every man's work, of what sort it is. If any man's work abide, which he hath built thereupon, he shall receive a reward. If any man's work burn, he shall suffer loss: but he himself shall be saved, yet so as by fire."
While this passage presents considerable difficulty, it is regarded by many of the Fathers and theologians as evidence for the existence of an intermediate state in which the dross of lighter transgressions will be burnt away, and the soul thus purified will be saved. This, according to Bellarmine (De Purg., I, 5), is the interpretation commonly given by the Fathers and theologians; and he cites to this effect:
- St. Ambrose (commentary on the text, and Sermo xx in Ps. cxvii),
- St. Jerome, (Comm. in Amos, c. iv),
- St. Augustine (Enarration on Psalm 37),
- St. Gregory (Dial., IV, xxxix), and
- Origen (Hom. vi in Exod.).
