< Many consider Acts and Epistles to be the "New Testament". The Gospels, having been written for the Jews they say, are considered part of the "Old Testament".
There are also quite a few sola scripture types who say that God wanted to make the Jews jealous hence the incarnation or that the baptism of Gentiles was an afterthought by God (afterthought -- more attempts to an anthropometric deity)
That is a Pauline innovation. I would be curious to see some Patristic commentaries on the subject of Paul's idea that God wanted to make Jews jealous and punished them by favoring the Gentiles (which, for a Jew St. Paul claimed to be is utterly unJewish!).
