A l’origine il y a un anti-judaïsme clairement de nature étatique, l’antisémitisme étant peut-être sa conséquence populaire (?)
A Profession Of Faith From The Church Of Constantinople in the year 325 C.E.(A.D.) Under The Emperor Constantine
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.
