“I renounce all customs, rites, legalisms, unleavened breads and sacrifices of lambs of the Hebrews, and all the other feasts of the Hebrews, sacrifices, prayers, aspirations, purifications, sanctifications, and propitiations, and fasts and new moons, and Sabbaths, and superstitions, and hymns and chants, and observances and synagogues. absolutely 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 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 Cain and the leprosy of Gehazi cleave to me, as well as the legal punishments to which I acknowledge myself liable. And may I be an anathema in the world to come, and may my soul be set down with Satan and the devils.”
(Stefano Assemani, Acta Sanctorium Martyrum Orientalium at Occidentalium, Vol. 1, Rome 1748, page 105)

Furthermore, any follower of the “Jewish Messiah” (Yeshua HaMashiach) who wished to join this “holy community” was compelled to adopt a different set of rules and customs. Subsequently special creeds were drafted, to which the Christian would have to swear such as:

“I accept all customs, rites, legalism, and feasts of the Romans, sacrifices. Prayers, purifications with water, sanctifications by Pontificus Maxmus (high priests of Rome), propitiations, and feasts, and the New Sabbath “So! dei” (day of the Sun, ), all new chants and observances, and all the foods and drinks of the Romans. In other words, I absolutely accept everything Roman, every new law, rite and custom, of Rome, and the New Roman Religion.”
