John Chrysostom
"Therefore, when I was sent for, I came without objection." He says this so they would not think that, although the matter was unlawful, he obeyed because Cornelius was a commander. Rather, all should ascribe it to God. For this reason he says that it is not permitted not only "to associate," but even "to draw near." "I ask, then: for what matter did you call me?" He asks not because he does not know. Peter knew everything from the vision and had heard it from the soldiers. But he wants them first to confess and dispose themselves toward faith. Therefore Peter said, "For what matter did you call me?" so that Cornelius might speak all these words.
