I've always wondered how the followers of a Jewish prophet could have hatred toward the Jewish people. I am not surprised in finding anti-semitism in early Christianity and neither does it cause me to condemn those who held to it. However, this does show that the fathers of the church may not have been right on everything.
"...Ephraim the Syrian wrote polemics against Jews in the fourth century, including the repeated accusation that Satan dwells among them as a partner. These writings were directed at Christians who were being proselytized by Jews and who Ephraim feared were slipping back into the religion of Judaism; thus he portrayed the Jews as enemies of Christianity, like Satan, to emphasize the contrast between the two religions, namely, that Christianity was Godly and true and Judaism was Satanic and false. Like John Chrysostom, his objective was to dissuade Christians from reverting to Judaism by emphasizing what he saw as the wickedness of the Jews and their religion.
In his Dialog of Justin, Philosopher and Martyr, with Trypho, a Jew, the Christian scholar Justin Martyr advanced arguments for the truth of Christianity and wrote to his imaginary Jewish opponent: "You think that these words refer to the stranger and the proselytes, but in fact they refer to us who have been illumined by Jesus. For Christ would have borne witness even to them; but now you are become twofold more the children of Hell, as He said Himself."
Saint Jerome (374-419 CE) - He denounced Jews as "Judaic serpents of whom Judas was the model.
" In his The Jews in the Roman Empire (Les Juifs dan L'Empire Romain) [Is this really a work by Jerome, or a modern history?] he wrote: "The Jews seek nothing but to have children, possess riches and be healthy. They seek all earthly things, but think nothing of heavenly things; for this reason they are mercenaries."
Saint John Chrysostom (ca 344 - 407 CE) - wrote of the Jews and of Judaizers in eight homilies Adversus Judaeos, Against The Jews (or Against the Judaizers) . These quotes are translations from the original Greek posted by Paul Halsall: other researchers give slightly different translations.
"Shall I tell you of their plundering, their covetousness, their abandonment of the poor, their thefts, their cheating in trade? the whole day long will not be enough to give you an account of these things. But do their festivals have something solemn and great about them? They have shown that these, too, are impure." (Homily I, VII, 1)
"But before I draw up my battle line against the Jews, I will be glad to talk to those who are members of our own body, those who seem to belong to our ranks although they observe the Jewish rites and make every effort to defend them. Because they do this, as I see it, they deserve a stronger condemnation than any Jew." (HOMILY IV, II, 4)
"Are you Jews still disputing the question? Do you not see that you are condemned by the testimony of what Christ and the prophets predicted and which the facts have proved? But why should this surprise me? That is the kind of people you are. From the beginning you have been shameless and obstinate, ready to fight at all times against obvious facts." (HOMILY V, XII, 1)
...Saint Fulgentius of Ruspe (467-533 CE) - In his "Writings", written about 510 CE, he states "Hold most firmly and doubt not that not all the pagans, but also all the Jews, heretic and schismatics who depart from the present life outside the Catholic Church, are about to go into eternal fire prepared for the devil and his angels."
