And that was both prescriptively and descriptively overridden.
Acts 1:8 (KJV)
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
Acts 8:5 (KJV)
Then Philip went down to the city of Samaria, and preached Christ unto them.
And if overridden, then it had served its purpose and was no longer in effect.
Neither of those has overridden what was said here in Acts 11.
Your quote above is speaking of the
church in Jerusalem who believed in the Messiah. "Them" is speaking of the Jews who were scattered after the persecution of Stephen. They were not preaching to the gentiles. They were not even to speak to the gentiles. Peter had not even had his vision of the sheet and his message of the clean and the unclean. Cornelius had not yet been approached and it took an act of God to get Peter to even speak to Cornelius. Notice what Peter says to this gentile.
Acts 10:28 And he said unto them,
Ye know how that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation; but God hath shewed me that I should not call any man common or unclean.
You have not yet addressed this.
Notice Acts 1 and Acts 8 come before Acts 11?
Acts 11:19 Now they which were scattered abroad upon the persecution that arose about Stephen travelled as far as Phenice, and Cyprus, and Antioch,
preaching the word to none but unto the Jews only.
