You bring up such a good point! Learning more about the history of Christian antisemitism has been quite the surprise for me – too often, it seems that even those same voices who yielded much fruit in Christian theology and defining Christian orthodoxy which remains sound to this day, have also unfortunately been given to antisemitic behaviors. Of course, history is a complex thing. It is good to remember our history so that we may learn what to keep from our past (of which there is much to keep), as well as what is good to discard (and on this topic in particular, there is an unfortunate amount which needs to be disposed of). Only after we have resolved our history to ourselves can we move forward to address the current ramifications of that history.
