This is Gregory Baum. A Jewish Catholic priest, he was the key writer of the early drafts of Nostra Aetate. He “converted” to Catholicism after fleeing the Nazis.
After Nostra Aetate was published, Baum left the priesthood. His mission was accomplished.
The Catholic Church has been under American (and by extension, Israeli) occupation since WW2. Everything published by the Vatican since 1945 should be viewed as compromised.
