John Chrysostom

"How then shall they call on Him in Whom they have not believed? and how shall they believe in Him of Whom they have not heard? and how shall they hear without a preacher? and how shall they preach except they be sent? as it is written."

Here again he takes from them all excuse. For since he had said, "I bear them record that they have a zeal of God, but not according to knowledge," and that "being ignorant of God's righteousness, they submitted not themselves" to it: he next shows, that for this ignorance itself they were punishable before God. This he does not say indeed so, but he makes it good by carrying on his discourse in the way of question, and so convicting them more clearly, by framing the whole passage out of objections and answers. But look further back. The Prophet, saith he, said, "Whosoever shall call upon the Name of the Lord shall be saved." Now somebody might say perhaps, "But how could they call upon Him Whom they had not believed? Then there is a question from him after the objection; And why did they not believe? Then an objection again. A person certainly may say, And how could they believe, since they had not heard? Yet hear they did, he implies. Then another objection again. "And how could they hear without a preacher?" Then an answer again. Yet preach they did, and there were many sent forth for this very purpose. And whence does it appear that these are those persons sent? Then he brings the prophet in next, who says, "How beautiful are the feet of them that preach the Gospel of peace, and bring glad tidings of good things!" You see how by the kind of preaching he points out the preachers. For there was nothing else that these men went about telling everywhere, but those unspeakable good things, and the peace made by God with men. And so by disbelieving, it is not we, he implies, whom you disbelieve, but Isaiah the prophet, who spake many years ago, that we were to be sent, and to preach, and to say what we do say. If the being saved, then, came of calling upon Him, and calling upon Him from believing, and believing from hearing, and hearing from preaching, and preaching from being sent, and if they were sent, and did preach, and the prophet went round with them to point them out, and proclaim them, and say that these were they whom they showed of so many ages ago, whose feet even they praised because of the matter of their preaching; then it is quite clear that the not believing was their own fault only. And that because God's part had been fulfilled completely.
