Jerome apparently had some confusion as to the differences between Nazarenes and Ebionites, a different Jewish sect, and that the Nazarenes probably never positioned themselves as being Christians. His criticism of the Nazarenes is noticeably more direct and critical than that of Epiphanius.
The Roman Emperor Constantine at the Council of Nicea (325 C.E.), declared a formal and complete break from all Jewish practices and interaction with Jews or Judaism.
The following creed is that of a church at Constantinople at the same period:
"I renounce all customs, rites, legalisms, unleavened breads & sacrifices of lambs of the Hebrews, and all other feasts of the Hebrews, sacrifices, prayers, aspersions, purifications, sanctifications and propitiations and fasts, and new moons, and Sabbaths, and superstitions, and hymns and chants and observances and Synagogues, and the food and drink of the Hebrews; in one word, I renounce everything Jewish, every law, rite and custom and if afterwards I shall wish to deny and return to Jewish superstition, or shall be found eating with The Jews, or feasting with them, or secretly conversing and condemning the Christian religion instead of openly confuting them and condemning their vain faith, then let the trembling of Gehazi cleave to me, as well as the legal punishments to which I acknowledge myself liable. And may I be anathema in the world to come, and may my soul be set down with Satan and the devils." [4]
There are no mentions of this group later than the fourth century.
