¹ sn The revelation of our Lord Jesus Christ refers to the Lord’s return, when he will be revealed (cf. the reference to the day of our Lord Jesus Christ in v. 8).

² sn It is debated whether this is a Corinthian slogan. If it is not, then Paul is essentially arguing that there are two types of sin, nonsexual sins which take place outside the body and sexual sins which are against a person’s very own body. If it is a Corinthian slogan, then it is a slogan used by the Corinthians to justify their immoral behavior. With it they are claiming that anything done in the body or through the body had no moral relevance. A decision here is very difficult, but the latter is to be preferred for two main reasons. (1) This is the most natural understanding of the statement as it is written. To construe it as a statement by Paul requires a substantial clarification in the sense (e.g., “All other sins…” [NIV]). (2) Theologically the former is more difficult: Why would Paul single out sexual sins as more intrinsically related to the body than other sins, such as gluttony or drunkenness? For these reasons, it is more likely that the phrase in quotation marks is indeed a Corinthian slogan which Paul turns against them in the course of his argument, although the decision must be regarded as tentative.

³ tc The Western and Byzantine texts, as well as one or two Alexandrian mss (D F G Ψ 33 Ï latt sy), combine in reading ἀδελφοί (adelfoi, “brothers”) here, while the Alexandrian witnesses (Ì⁴⁶ א A B C P 81 630 1175 1739 1881 2464 co) largely lack the address. The addition of ἀδελφοί is apparently a motivated reading, however, for scribes would have naturally wanted to add it to ἐπαινῶ δὲ ὑμᾶς (epainw de Juma", “now I praise you”), especially as this begins a new section. On the other hand, it is difficult to explain how the shorter reading could have arisen from the longer one. Thus, on both internal and external grounds, the shorter reading is strongly preferred.
