The first Christians such as Justin Martyr, the Church Fathers such as Augustine, the Reformers such as Luther were all anti-Semites. Why was that so?
Here are some quotes:
Luther: "Accordingly, it must and dare not be considered a trifling matter but a most serious one to seek counsel against this and to save our souls from the Jews, that is, from the devil and from eternal death. My advice, as I said earlier, is: First, that their synagogues be burned down, and that all who are able toss in sulfur and pitch; it would be good if someone could also throw in some hellfire. That would demonstrate to God our serious resolve and be evidence to all the world that it was in ignorance that we tolerated such houses, in which the Jews have reviled God, our dear Creator and Father, and his Son most shamefully up till now but that we have now given them their due reward."
John Chrysostom: "Again the Jews, the most miserable and wretched of all men. But today the Jews, who are more dangerous than any wolves, are bent on surrounding my sheep; so I must spar with them and fight with them so that no sheep of mine may fall victim to those wolves. Isaiah called the Jews dogs and Jeremiah called them mare-mad horses. This was not because they suddenly changed natures with those beasts but because they were pursuing the lustful habits of those animals."
Pope Clement VIII: "All the world suffers from the usury of the Jews, their monopolies and deceit. They have brought many unfortunate people into a state of poverty, especially the farmers, working class people and the very poor. Then, as now, Jews have to be reminded intermittently that they were enjoying rights in any country since they left Palestine and the Arabian desert, and subsequently their ethical and moral doctrines as well as their deeds rightly deserve to be exposed to criticism in whatever country they happen to live."
