The apostles’ preaching touched the hearts not only of Jews but also of Gentiles, since the Kingdom from the very beginning was open to everyone who was ready to entrust himself to the Savior. Something else is interesting: these recent Gentiles who come into the Church are perceived by the sacred writer as an integral part of the new people of God, as those who were “appointed beforehand” to eternal life, to the life of the Kingdom. In principle, of course, there is nothing especially unusual in such a vision of the Church as the new people of God. According to the ideas generally accepted in the synagogue milieu of that time, the people of God had been conceived by God before the creation of the world, just as the Messiah had been. And already during the lifetime of the first Christian generation the Church transferred this understanding to itself as the new people of God.
But with regard to the Gentiles the situation was not so unambiguous. Of course, the prophets said more than once that with the coming of the Messiah the Gentiles would turn to the God of Israel and enter the people of God as an integral part of it. But such entry evidently did not mean that God’s plan for His people included the Gentiles too from the very beginning. It was a manifestation of God’s mercy: though He had promised the Gentiles nothing in advance, through the Messiah He nevertheless gives them the possibility of becoming participants in His plan for the salvation of the world. And the Church, as can be seen, extended this idea of God’s providence to all its members, regardless of origin.
Such a rethinking of the boundaries of the people of God was extremely important. Under the traditional Jewish definition of those boundaries, no Gentile, even one who believed in the God of Israel, fell within them unless he accepted Judaism in its fullness and became a Jew. The Church, however, from the very beginning linked the boundaries of the people of God not with the Jewish people as an ethnic group and not with the Synagogue, but with the person of the Messiah. The people’s boundaries were expanded by such an approach, but the former covenants that God had made with His people were not thereby devalued: relationship with God is a single and spiritually whole process, in which every stage is important, beginning with Abraham and ending with Christ. And there was also the covenant with Noah, that collective image of all the righteous of the Gentile world, to whom the new view of the people of God opened a path into the Church without passing through the Synagogue. Thus the Kingdom united the former people of God with every righteous person who sought true life in all its fullness.
