That still does not make Judaism and Catholicism similar.
Jesus celebrated all the holidays, the Passover Seders, taught at the temple.
Now our Protestant churches, COMPLETELY IGNORE Judaism and act as though the religions are two entirely separate belief systems, WHICH THEY ARE NOT!
Jesus came to put the spirit back in the law, he changed not one letter of the law.
I explain to my kids that Christianity is Judaism plus; Christianity is really a kind of Judaism
Has there been persecution of the Jewish adherents by Christians? Unfortunately, yes, pathetically yes.
(On the other hand, I was babysitting a little child in a Jewish home and he told me his grandfather hated Christians.) But as far as I can tell, the Jewish people have never banded together to kill and humiliate Christians.
