And when he was disposed to pass into Achaia, the brethren wrote, exhorting the disciples to receive him: who, when he was come, helped them much which had believed through grace: When he was disposed to pass into Achaia - There is a very long and important addition here in the Codex Bezae, of which the following is a translation: But certain Corinthians, who sojourned at Ephesus, and heard him, entreated him to pass over with them to their own country. Then, when he had given his consent, the Ephesians wrote to the disciples at Corinth, that they should receive this man. Who, when he was come, etc. The same addition is found in the later Syriac, and in the Itala version in the Codex Bezae.
Which had believed through grace - These words may either refer to Apollo, or to the people at Corinth. It was through grace that they had believed; and it was through grace that Apollo was enabled to help them much.
The words δια της χαριτος, through grace, are wanting in the Codex Bezae, the later Syriac, the Vulgate, one copy of the Itala, and in some of the fathers. But this omission might have been the effect of carelessness in the writers of those copies from which the foregoing were taken: the words convey the same idea that is expressed by St. Paul, 1 Corinthians 3:6 : Paul planted, and Apollos watered; but God gave the increase. Though this eminent man became the instrument of mightily helping the believers in Corinth, yet he was also the innocent cause of a sort of schism among them. For some, taken by his commanding eloquence, began to range themselves on his side, and prefer him to all other teachers. This evil St. Paul reprehends and corrects in his first epistle to the Corinthians. St. Jerome says that Apollo became bishop of Corinth.
