The church age is not the times of the Jews.
Luke 21:24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
Deflect, deflect and then deflect some more.
Were there or were there not Jews in the Church?
You said the Church was built by the Gentiles, hence my question.
Try to focus and answer that question.
Oh, and nice dodge once again regarding the question as to why Jesus, God, THE ROCK, chose for Simon a name which means rock.
