1 Corinthians 3:12-13

3:12 If anyone builds on the foundation with gold, silver, precious stones, wood, hay, or straw, 3:13 each builder’s work will be plainly seen, for the Day will make it clear, because it will be revealed by fire. And the fire will test what kind of work each has done.

sn The various materials described here, both valuable (gold, silver, precious stones) and worthless (wood, hay, or straw) refer to the quality of work built on the foundation, or possibly to the motivation of those doing the building. The materials themselves have been understood (1) as deeds or (2) as people (since ultimately the passage is addressing those who minister to others).

tn Grk “each one’s.” Here “builder’s” is employed in the translation for clarity.

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).

tcαὐτό (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.
