1 tn Grk “each one’s.” Here “builder’s” is employed in the translation for clarity.
2 tn In an attempt to clarify the referent, some translations add “of Christ” after “Day” (so TEV); others specify this as “judgment day” (NLT) or “the day of judgment” (CEV).
sn The Day refers to the Day of the Lord Jesus Christ (cf. 1:8; 5:5) when each Christian worker will appear before Christ for evaluation of his ministry. Paul’s constant motivation was to be pleasing to the Lord in that day (2 Cor 5:9-10) and receive his commendation (1 Cor 4:5).
3 tc ‡ αὐτό (auto) is found at this point in v. 13 in a number of significant witnesses, including A B C P 33 1739 al. But Ì46 א D Ψ 0289 1881 Ï latt lack it. The pronoun could be a motivated reading, designed to intensify Paul’s statement. On the other hand, it could have been deleted because the article alone made the reference already clear. In this instance, the possibility of scribal addition seems more likely than scribal deletion, although a decision is difficult. NA27 includes the word in brackets, indicating doubt as to its authenticity.
sn It is unclear whether the phrase it will be revealed by fire describes the Day (subject of the previous clause) or each one’s work (subject of the clause before that).
4 tc Most later witnesses (א2 Ï sy) add “fasting and” (τῇ νηστείᾳ καί, th nhsteia kai) before “prayer.” But such an addition is motivated by ascetic concerns; further, its lack in Ì11vid,46 א* A B C D F G P Ψ 33 1739 1881 2464 al latt co argues decisively against its authenticity.
5 tn Grk “and be together again.”
