John Chrysostom
He did not say, only of the Twelve, but also of all the others. He says all this both from humility and with the intention I mentioned, namely, to dispose his hearers to accept the words that follow more readily.
If instead he had said, "You must believe me that Christ is risen because I saw Him, and I am more trustworthy than all the witnesses because I labored more than all," he might have offended his hearers by such words.
But now, by first depicting the circumstances that serve for his humiliation and condemnation, he both softens his speech and prepares the way for faith in his testimony.

Therefore, as I said, he does not simply present himself as last and unworthy of the name Apostle, but gives the reason: "because I persecuted the Church of God." And although all this had been forgiven him, he himself by no means forgets it, wishing to show the greatness of grace. Therefore he continues: "But by the grace of God I am what I am" (1 Cor 15:10).
Even if we ascend to the very summit of the virtues, if we conscientiously compare our good deeds with God's benefits, we shall clearly see that our virtues do not equal even the smallest part of what God has done for us.
By this very thing, that is, by humility and modesty, each of the saints was glorified. To be convinced of this, listen to the teacher of the universe, this heaven-ascending soul. After accomplishing such virtues, and after such testimony about him from above, "for he is a chosen vessel of Mine," he does not forget his sins.
Rather, he constantly bears them in mind. He does not allow himself to forget even that for which he was perfectly sure he had already received forgiveness in baptism. He cries out and says, "I am the least of the Apostles, and am not worthy to be called an Apostle."
Then, so that we might know the full depth of his humility, he added: "because I persecuted the Church of God." What are you doing, Paul? The Lord, by His mercy, forgave and blotted out all your sins, and do you still remember them?
