The council of Nicea II did just that!
Nicea II, in the eighth century, officially banned Jewish life in Jesus. All who continued to practice circumcision, Sabbath observance or other Hebrew rites were to be banned from the Church. Many think that the first Council of Nicea in 325 A.D. precluded Jews from Jewish life in Jesus. However, there is no canon of this council explicitly dealing with this issue. Apparently, many have confused Nicea I and Nicea II. Only universal councils were universally received and became binding to the whole Church. Regional councils, such as Toledo, Elvira, Antioch and Laodocia making such decisions against Jewish life in Yeshua had influence, but did not become universal law. Nicea II provides us with universal law. The text translated from the Latin follows:
"Because those from the Hebrew religion have been deceived, they seem to mock Christ as God, pretending to become Christians, but they deny him as they openly and secretly keep the Sabbath and follow other practices in the manner of the Jews. We determine that they are not to be received into communion, nor into prayer, nor in the Church, but the Hebrews are manifestly according to their own religion: their children are not to be baptized; nor is a slave to be purchased or acquired. But if anyone of them will convert out of a sincere faith and heart and will make a profession of faith with all his heart, disclosing their customs and practices so that others might be exposed and corrected, he is to be received and baptized, and also his children; but indeed we decree that they are to be observed so that they depart from Hebrew practices, otherwise they are not to be admitted at all."
