the Catholic Church has had one great, fierce, and enduring enemy. That enemy is the jews
So where exactly in the biblical canon are christians commanded to treat jews as the enemy? Kind of defeats the whole purpose of "love thy neighbor", doesn't it? And why do you feel as if it's place of the church to oppose this "great, fierce, and enduring enemy"? After all, your "god" reserves the right of vengence for himself in rather specific words.
the people who rejected their King and their God, who crucified Him,
Okay... So you care to tell me why your holy book makes it quite clear that jesus was killed by the Romans. The jews who were present might not have objected too it but complicity and apathy are not the same as murderous intent and malice aforethought.
and who prophesied the stain that should forever mark them, in their defiant shout: "HIS BLOOD BE UPON US AND UPON OUR CHILDREN!"
So your "god" is so petty and vindictive that he/she/it would punish not only the whole religious/ethnic group, but all their children too? And for for them all to be punished for a slight made by a minority of Jews? That's not justice, that's not even vengence, that's just pure spite and hateful vindictiveness. It's literally saying that certain people, mainly those you don't like, should be punished or even killed for what one of their ancestors may or may not have said or done. Any "god" who would lay down such curses on completely innocent members of his supposed "chosen people" is not only immoral, but malevolent and unworthy of worship.
But I don't believe your "god" really did any of those things, I don't even believe your "god" exists, but what I do believe is that you hate jews for whatever irrational and quite possibly fictional reason (Likely a bunch of conspiracy theories involving cabals of "jewish bankers"; various secret societies; the new world order; the Protocols of Zion, a well known forgery; and one cannot forget the vast hidden networks of "Crypto-Jew's" that are invariably said to include nearly every famous or infamous politician, businessman, or celebrity of the past 100 years.), and that you'll cherry pick, twist, and even fabricate parts of the bible that you think you can use to justify or rationalize your hatred.
In other words, you are not a pious christian, you are not a righteous crusader, not even a stalwart sentinel against international jewry, you're simply a pathetic bigot who wrongly believes that his choice of religion has somehow made him superior to others, an infantile bigot throwing impotent tantrums when those "lesser" people don't realize or acknowledge your percieved inherent superiority.
