St. John Chrysostom (349-407)
(known as the “golden mouthed” due to his eloquence in speech:

They are become worse than the wild beasts, and for no reason at all, with their own hands, they murder their offspring, to worship the avenging devils who are foes of our life… … It is incumbent upon all Christians to hate the Jews.

Pope Paul IV 1555:

“Cum nimis absurdum. Forasmuch as it is highly absurd and improper that the Jews, condemned by God to eternal slavery because of their guilt should, on the pretext that they are cherished by Christian love, and permitted to dwell in our midst, … and considering that the Roman Church tolerates the Jews in witness of the true Christian faith… we do therefore order the following measures, which are perpetually valid…”
Followed with a list of decrees against the Jews.
