The root cause of anti-Semitism inside the Church walls is the the idea of Replacement theology or supersessionism. The roots of Replacement Theology and its fruit of anti-Semitism go back to the very beginning of Christianity. This is ironic when you consider the fact that the Church began as a Jewish institution. It was founded in Judea by Jews who were followers of a Jewish Messiah, and all its founding documents were written by Jews. (1) The oldest Christian symbol that has ever been found clearly emphasizes the Jewish origins of Christianity. The symbol is carved into artifacts found in Jerusalem that date back to the First Century.(2) It shows the fish, the symbol of the Church, emerging from Jewish roots, represented by the Menorah and the Star of David. The fish became a symbol for Christians because the word for fish in Greek is icthus, and Christians used the letters of this word, ICTHUS, as an acronym for Iesous, Christos, Theos, Huios, and Soter, meaning Jesus Christ, God’s Son and Savior. But the distinctive Jewish flavor of early Christianity was not to last long. As the Church began to spread beyond Judea, its message was embraced by more and more Gentiles who had no interest in maintaining contact with the Church’s Jewish roots. Even worse, the new Gentile leaders began to turn against the Jews by characterizing them as “Christ killers.” Consider the following examples:
St. Augustine (354-430 AD) - Asserted that the Jews deserved death but were destined to wander the earth to witness the victory of the Church over the synagogue.”Source
That is not the root cause of anti-semitism. Before I tell you the real root, let me comment on that article you cite.
The quotes do not list the letters these statements are from. They only list books written by other people. They should have mentioned the document for each quote so I can confirm its veracity.
However, you could say it is right about the Council of Elvira and in a sense that is still true today. Practicing Jews also prefer their children marry Jews. No big deal, both sides have their reasons.
The info about council of Nicea is sort of correct but it was Constantine that was angry at the Jews for the reasons stated below. And BTW, the date of Easter was not really changed; it was set to a uniform date* (Christians were celebrating Easter on different dates)* and Constantine gave his opinion that the chosen date should not coincide the Passover(some Christians were celebrating Easter on what we now call Good Friday).
So as an aside, all Christians today celebrate Easter on the Sunday after Good Friday because of the Council of Nicea. (Oh, Oh! the Protestants celebrate Easter on the Sunday after Good Friday because the Catholic Church said so.:D)
Now for the true root cause:
1) Shortly after the crucifixion of Jesus the Temple was destroyed as retaliation from the Romans for not only revolting against the Empire but also defeating the Romans in a battle during the revolt.
2) After the Crucifixion of Jesus, the Roman Empire began to collapse, facing similar problems that we are dealing with today.
3) When Constantine took control of the entire Empire he made the observation that only his fourth of the Empire did not persecute the Christians. Neither him nor his father.
4) He came to the conclusion that he was given the entire Empire by the Christian God because he and his father did not persecute the Christians.
5) He eventually came to the conclusion that the Jews and the Romans were punished for the Crucifixion.
6) He believed the Jews had gone crazy after having killed their own God and that is why they revolted.
7) He believed the Roman Empire was collapsing because of its part in the Crucifixion.
8) Constantine then blamed the Jews for the problems of the Roman Empire. He believed they should have recognized their own God and He was angry the Jews had gotten them involved.
As pagans began to come into the Christian Church many harbored this belief. And so that is when people began to blame Jews when things went bad. That is the root of people saying things like "Hey, the economy is bad. It must be the Jews' fault."
Of course we can not say that in fact the Jews and the Romans were punished by God for the crucifixion. But it is true that both did suffer after the Crucifixion. I am also not saying Constantine was correct in what he believed, but the evidence shows that is what he believed.
But the bottom line these anti-semites are just jerks looking to find scapegoats. In the past these types of bad Catholics have become groups like atheistic socialists and then persecute the Catholics in places like Spain, Mexico, Cuba, Poland, Russia, etc.
