Gentiles added into Gods Plain?

Question

Where in the bible that the Gentiles was added into Gods Plain?

Answer 1

Acts 13:45-46 "But when the Jews saw the multitudes, they were filled with envy; and contradicting and blaspheming, they opposed the things spoken by Paul. Then Paul and Barnabas grew bold and said, 'It was necessary that the word of God should be spoken to you first; but since you reject it, and judge yourselves unworthy of everlasting life, behold, we turn to the Gentiles.'"

Acts 14:27 "Now when they had come and gathered the church together, they reported all that God had done with them, and that He had opened the door of faith to the Gentiles."

Acts 15:7-9 "And when there had been much dispute, Peter rose up and said to them: 'Men and brethren, you know that a good while ago God chose among us, that by my mouth the Gentiles should hear the word of the gospel and believe. So God, who knows the heart, acknowledged them by giving them the Holy Spirit, just as [He] [did] to us, and made no distinction between us and them, purifying their hearts by faith.'"

Acts 22:21 "Depart, for I will send you far from here to the Gentiles"

Gal 2:6-7 "those who seemed to be something, added nothing to me, but on the contrary, they saw that the gospel for the uncircumcised had been committed to me, as the gospel for circumcised was to Peter"

Eph 3:3,6 "By revelation He made known to me the mystery... that the Gentiles should be fellow heirs of the same body and partakers of His promise in Christ through the gospel. "

Answer 2

It's called Pauline or Paulist doctrine.

Paul claimed his mission was to bring the gospel to the Gentiles after it was rejected by Hebrews. He eliminated the need for pagans to comply with Hebrew laws.

Pauline doctrine is what most (vast majority) of "Christians" practice.
