Then he lessens the weight of the sin by calling it zeal. Besides this, he keeps silent about the name of the person who revealed to him the Corinthians’ faults, so as not to expose him to their anger and indignation.
But so that his word might be trustworthy, he does not speak wholly indefinitely. In a certain way he limits it, saying that those of Chloe’s household informed him of this.
Why did Paul place himself first? This order of names made by him proceeds not from the highest to the nearest, but from the lower to the higher. Therefore, although he placed his own name first, in reality it should be counted last.
He placed them in this order to show that the last were those who called themselves disciples of Christ, and thereby to rebuke them more strongly for their division of mind.
"My brethren," he says, "those of Chloe’s household have informed me concerning you that you have strife. Namely, that one of you says, I am a disciple and follower of Paul; another, I am of Apollos; one, I am of Cephas; and another, I am of Christ" (Chrysostom, Theodoret, Oecumenius on this passage).
Some affirm that the Corinthians did not call themselves disciples of Paul, Apollos, or Cephas, but of certain other teachers. Paul transferred this to himself and Apollos, as he himself says.
First, he did this so as not to shame those teachers, and consequently not to harden them. Second, he did it to express the errors of the Corinthians more strongly.
For if they sinned even when they called themselves disciples of their true teachers, that is, Paul, Apollos, and Cephas, then they erred much more when they called themselves disciples of men who had not been sent by God and did not have the gift of Gospel preaching.
For this same reason he joins the name of Christ to himself and the other two. He does this to show how great an iniquity they committed by comparing the Master with servants.
But if we take these words of Paul in their proper and simple meaning, we will not err in this either. It is known that Paul first preached the Gospel in Corinth, and after him Apollos (Acts 18:1; Acts 19:1).
After him, or together with him, some of Peter’s disciples perhaps preached. Therefore those taught and converted to the faith by Paul said of themselves that they were disciples of Paul.
Those converted by Apollos said that they were of Apollos. Those taught by the disciples of Cephas were called Cephas’s. Those who did not separate from one another and were always of one mind said of themselves that they were disciples of Christ.
This opinion is confirmed by the following words of Paul: "Was Paul crucified for you? Or were you baptized in the name of Paul? Who then is Paul, and who is Apollos, but ministers through whom you believed, as the Lord gave to each one?
I planted, Apollos watered, but God gave the growth" (1 Cor 1:12-13; 1 Cor 3:5-6).
When Paul said, "These things I have applied to myself and Apollos" (1 Cor 4:6), this means that he kept silent about all the names of the other teachers, implying them under his own name and that of Apollos.
Having said this, he immediately makes known what impious consequence comes from such contentiousness and strife.
