TWO GENTILES JESUS SAVED

[EarlyActs]

Yes, and he is saying this to Jewish Christians to remind them of the prophecies of this/these event(s).

Yes, agreed.

There was Gentile Christians present but a minority. Messiah was Promised to Israel and to Israel He came. And for the first couple of decades (Paul was saved AD34-37) until the destruction of their Temple God added a remnant or Israeli-foundation to the continuation of His Church-building (originally begun when the Tabernacle was built in the desert post-Egypt) until the Times of the Gentiles still yet future would begin.
Remember, Jesus sent His apostles into Gentile lands to herald the arrival of Israel's Messiah to the twelve tribes scattered in those lands to solidify that His Promise was kept before He was to do this "new thing" prophesied by Isaiah, which was the grafting in of Gentiles to the Olive branches of the Israeli Tree.

re the last line: it was the promise that was kept. The mission to the nations is not an afterthought, a plan B in case something didn't work in Israel. The kingdom did come. He was enthroned, Davidically, in the resurrection (see the exact grammar of Acts 2:30-1--and of course the conclusion of the talk).

In Rome at least, when Jewish Christians came back to fellowship after Claudius eviction, the Gentiles were majority. chs 14, 15 and 11 certainly show parts specifically to embedded Gentiles.

I sense that Paul was back and forth between synagogues and homes/halls in Acts scenes in Little Asia so I can't imagine him telling people only to come to one place. They wanted to hear him regardless of place.
