The origins of Christian antisemitism are much older than the institution of Jewish moneylenders. It may well have been inherited from Hellenistic pagan converts- there was much friction between Hellenes and Jews in pre- and early- Christian times (see Josephus' history of the Jewish Wars).

As for Carter, I doubt if he had an antisemitic bone in his body, and despite the mention of the crucifixion, he was one of that generation of Anglicans who thought the implementation of Jesus' teachings on social justice as more important than "conjuring tricks with bones".
