Paul and his companions no longer strictly followed the rule followed by the first witnesses, who had been forced to leave Jerusalem because of persecution. Those witnesses testified only to Jews; these were ready to testify to anyone ready to listen and accept their witness. In this respect the situation had changed radically. And the point is not simply the widening of the audience. The point is where the boundary of God's people runs. To those first witnesses it seemed self-evident that these boundaries coincided with the boundaries of the Jewish people.
They were, of course, Christians, or more precisely messianists, since messianists from among the Gentiles came to call themselves Christians. They had no doubt that Jesus of Nazareth was the Messiah and the Son of God. But they were just as sure that one could follow Him only by being a Jew. And if you were not born a Jew, then first you needed to become one by accepting Judaism, and only then could there be talk about the Messiah.
They saw the Church as a continuation of the Jewish people and as part of it, as its messianic component. Paul and his companions saw the situation quite differently. For them the Church was not a simple continuation of the Jewish people and not its messianic part. For them the Church is the people of God in all its fullness. And belonging to it is not determined by belonging to the Jewish people. Of course, the Church is open to every Jew who accepts Jesus as the Messiah and as the Son of God. But it is just as open to anyone else, even if that person has no connection to Jewishness at all.
Only one thing matters: a person must accept Jesus as the Messiah and as the Son of God. And he must have his own deeply personal relationship with Him. The point here, of course, is not that Paul deliberately revised the traditional norms of the Torah in order to widen the boundaries of the Church. The point is that God opened His Kingdom to the Gentiles, and Paul could not fail to know this. And the boundaries of the Church, the one with a capital letter, coincide with the boundaries of the Kingdom. To cross them, one does not have to be a Jew.
This means that if somewhere in a large, or not very large, city the Jewish community as a whole remains indifferent to the witness about Christ, then one can and must testify to everyone else. Not in spite of the local synagogue, but simply because in that same city there may be people ready to enter the Kingdom and therefore the Church. To make their entrance into the Church depend on the attitude of the Church of the local Jewish quarter would be wrong and unjust toward them. More than that, it would be a direct violation of God's plan and an obstruction of His action in the world. No true witness of Christ would do such a thing, including, of course, Paul and his companions.
