2 Corinthians 10:15

Someone who takes pride in his own work is not being excessively proud of himself. A prudent man does not rely on the labors of others. This is why Paul does not claim any credit for those who have come to faith by the preaching …

"Not glorying beyond" our "measure," that is, "in other men's labors, but having hope that as your faith groweth, we shall be magnified in you according to our province unto further abundance, so as to preach the Gospel even unto the parts beyond you, and not to glory in another's province in regard of things ready to our hand." He sets forth a large accusation of them on these grounds, both that they boasted of things without their measure, and of other men's labors; and that whilst the whole of the toil was the Apostles', they plumed themselves upon their labors. 'But we,' says he, 'showed these things in our deeds. We will not imitate those men therefore, but will say such things where our deeds bear us witness. And why,' saith he, 'do I say, you?' "for I have hope that as your faith groweth;" for he doth not assert absolutely, preserving his own character, but, 'I hope,' he says, 'if you make progress, that our province will be extended even farther, "to preach the Gospel in the regions beyond." For we shall advance farther yet,' he says, 'so as to preach and labor, not so as to boast in words of what other men have labored.' And well did he call it "province and measure," as though he had come into possession of the world, and a rich inheritance; and showing that the whole was wholly God's. 'Having then such works,' he says, 'and expecting greater, we do not boast as they do who have nothing, nor do we ascribe any part to ourselves, but the whole to God.'

The primacy of knowledge the apostle shows to those capable of reflection, in writing to those Greeks of Corinth, in the following terms: "But having hope, when your faith is increased, that we shall he magnified in you according to our rule abundantly, to preach the Gospel beyond you." He does not mean the extension of his preaching locally: for he says also that in Achaia faith abounded; and it is related also in the Acts of the Apostles that he preached the word in Athens. But he teaches that knowledge (gnosis), which is the perfection of faith, goes beyond catechetical instruction, in accordance with the magnitude of the Lord's teaching and the rule of the Church.

He shows that those people boast in the labors of the apostles and boast without measure, that is, excessively and in others' labors. But we are not like that; rather, having reached you, we boldly say that we have reached you. In this we hope, …

Therefore he draws the conclusion, saying: therefore, when I glory in you, I am not glorying beyond measure. Hence he says: We do not boast beyond limit, in other men's labours, where someone else laid the foundation of faith. Then when he says, but our …
