Purification imagery is expanded in verse 15. Earlier Paul introduced the idea of reward:
“wages” in verse 7 and “wage” in verse 14. Paul is clearly referring to Christians that will not be
condemned, but who will receive a heavenly reward. However, “if someone’s work [ergon in
Greek] is burned up,” that is, found to be defective, he “will suffer loss” (1 Cor 3:15). The Greek
word that is translated as “suffer loss,” zemiothesetai, comes from the word zemioo. In the
Septuagint this Greek word is always used in the sense of punishment. The Septuagint’s use of
Greek words is an important tool in understanding the use of Greek words in the New
Testament because about 85% of the time the New Testament cites the Old Testament it
quotes the Septuagint not the Hebrew Old Testament. Thus when a person’s works are
defective he will suffer punishment, a period of purification: “that one will suffer loss; the
person will be saved, but only [houtos] as through fire” (1 Cor 3:15).
To explain this state of temporary punishment after death, which some will undergo, the early
Church in the West used the Latin word purgatorium from which we derive the English word, a
purgatory. Purgatorium, the state, and purgativus, the action, refer to the same reality, namely, purification. Latin, of course, was the language spoken in the west. Two additional observations
need to be made regarding this text.
Paul’s use of houtos, “but only as through fire” (1 Cor 3:15) finds an echo in Peter’s first letter in
which he also addresses the issue of purification: “so that the genuineness of your faith, more
precious than gold that is perishable even though [houtos] is tested by fire, may prove to be for
praise, glory, and honor at the revelation of Jesus Christ” (1 Pet 1:7).
Lastly, “works,” [ergon in Greek], are significant because of their relationship to salvation.
Clearly, when they come from human nature or in connection with the laws of the Old
Testament they are powerless to contribute to our salvation. “For by grace you have been
saved through faith; and this is not your own doing, it is the gift of God – not because of works
[ergon in Greek], lest any man should boast” (Eph 2:8-9; see also Rom 2:20, 27-28). However,
Paul does not reject the necessity of “works” as is clear in the next verse. “For we are his
workmanship, created in Christ Jesus for [the Greek word gar introduces a purpose clause: “for
the purpose of”] good works [ergon in Greek], which God prepared beforehand, that we should
walk in them” (Eph 2:10; see also Tit 3:5-8, 14; 1 Pet 1:1-20; Jas 2:24; Phil 2:12-13; 1 Cor 15:10).
