John Chrysostom
"When the Gentiles heard this." This also made the apostles themselves more zealous, because the Gentiles were receiving what the Jews ought to have received by listening. It grieved the Jews even more. "When the Gentiles heard this," says the writer, "they rejoiced and glorified the word of the Lord, and as many as were appointed to eternal life believed." That is, they had been chosen beforehand by God. He does not speak simply of "the Gentiles," but of all. This is precisely what the words "were appointed to eternal life" signify. This is a sign that they were accepted according to the will of God. He said "appointed" to show that it was not by compulsion. For he says, "Whom He foreknew, He also predestined" (Rom 8:29).
