The two catalogues of sins with which this chapter closes remind us, by way of contrast, of the two characteristic graces of Christianity: self-will or party spirit, in all its forms, is opposed to brotherly love, and self-indulgence, in all its forms, to personal purity. There is much in this Epistle which would be called by some people theological and transcendent; but no one knew better than Paul that, though Christianity must be capable of an intellectual construction, it is not an intellectual system in essence, but a new moral life. He was deeply concerned, as we have repeatedly seen, that the Corinthians should think right thoughts about Christ and the Gospel; but he was more than concerned, he was filled with grief, fear, and shame, when he thought of the vices of temper and of sensuality that prevailed among them. These went to the root of Christianity, and if they could not be destroyed it must perish. Let us turn our eyes from them to the purity and love that they obscure, and lift up our hearts to these as the best things to which God has called us in the fellowship of His Son.
[106] Αὐτὸς ἐγώ in ver. 13 has a peculiar emphasis, not easily explained. It cannot mean "_I_ did not, though my assistants did," for this is denied in ver. 18. Neither can it mean "_I_ did not, though the Judaists did," for whatever is opposed to αὐτὸς ἐγώ must nevertheless be conceived here as belonging to the same category, which the Judaists did not. Possibly it only separates the _person_ expressly from his _works_, just recited, and has the same sort of value as in Rom. ix. 3, where it emphasises the person as opposed to the heart and conscience.
[107] This is the reading of our Revisers, and of Westcott and Hort's text. In their margin they read: "I will very gladly spend, etc., if loving you [ἀγαπῶν instead of ἀγαπῶ] more abundantly I am loved the less." This reading and punctuation are adopted by a number of scholars, but explained in two ways:--(1) As in the Authorised Version, "_though_ the more abundantly," etc. But εἰ ("if"), which is the true reading (not εἰ καί), cannot be translated "though." (2) By others it is rendered, "I will very gladly spend, etc., if the more abundantly I love you the less I am loved": that is, "if things have come to such a pass between us that the natural relations are utterly inverted, I will make any sacrifice to restore them to a better footing." This is insipid and flat to the last degree: textual and psychological considerations combine to support the Revisers text.
[108] Πάλαι is the true reading, not πάλιν. Westcott and Hort retain the interrogation.
[109] This is also suggested by the reading ταπεινώσει, which Tischendorf adopts in ver. 21, with B, D, E, F, etc. א, A, K, followed by Westcott and Hort, have ταπεινώσῃ.
[110] It is more natural to construe ἐπὶ τῇ ἀκαθαρσιᾳ κ.τ.λ. with μετανοησάντων than with πενθήσω.
