Was Deicide officially taught in American Catholic (“parochial”) schools and if so, when did it officially end?
This isn't a Catholic thing it's a Christian thing and historically and in modern times is more associated with scapegoating, superstition, and prejudice than it is with main stream Christian beliefs.
No it has never been official Catholic doctrine. The Catholic church has actually officially refuted this belief several times since it's inception.
- Pope Clement VI by a papal bulls dated July 6, 1348, and 1349.
- Council of Trent (1545)
- Vatican Council II (1962)
I infer it has been continuously refuted by Catholic leadership due to it's at times pervasive, persistent, and disturbing support among the laity and some clergy.
The Catholic church overall position on anti-Semitism historically speaking is mixed.
But they cried out, Away with him, away with him, crucify him. Pilate saith unto them, Shall I crucify your King? The chief priests answered, We have no king but Caesar.
“Why? What crime has he committed?” asked Pilate. But they shouted all the louder, “Crucify him!”
24 When Pilate saw that he was getting nowhere, but that instead an uproar was starting, he took water and washed his hands in front of the crowd. “I am innocent of this man’s blood,” he said. “It is your responsibility!”
25 All the people answered, “His blood is on us and on our children!”
Claims of Jewish Deicide is classic anti Semitism and predates the formation of the Catholic Church(325 AD) by nearly two centuries. It is a prevalent justification for anti-Semitism historically speaking from Christians.
- The earliest recorded instance of an accusation of deicide against the Jewish people as a whole – that they were collectively responsible for the death of Jesus – occurs in a sermon of 167 CE attributed to Melito of Sardis entitled Peri Pascha, On the Passover.
While it has never been official dogma of the Catholic Church it has been and continues to be a demonstration of anti-Semitism which remains among some isolated Christians to this day.
Cadets say religious bias growing at Air Force Academy (2005)
There have been 55 complaints of religious discrimination at the academy in the past four years, including cases in which a Jewish cadet was told the Holocaust was revenge for the death of Jesus and another was called a Christ killer by a fellow cadet.
