Firstly, do you not notice that you just repeated, word for word, what Muslim clerics say today? "We disagree with terrorism, it's a perversion of our faith." You don't buy that. Why?
Because when someone perverts your faith, you do something about that. When a foreign women unwittingly gave a teddy bear the name Mohammad, they marched with machetes threatening to kill her. Can you name a single demonstration against terrorism in the Muslim world? Of course not.
You would not take this "logic" from a parent either. "My son split someone's head open? Oh no, that's not what I told him; that's perversion of my child-rearing principles." You wouldn't buy this cr-p, would you?
Why do you close your eyes not only on the questions of principle but on the history of the Church itself. Has it not excommunicated various individuals for various transgressions? Of course it did. But not for burning synagogues, not for raping Jewish women, not for hanging Jewish men, not for stealing Jewish property. Ever.
No less than (Portuguese) crusaders --- the soldiers of Christ willing to die for him! --- were excommunicated en masse just for "drunkunness and generally unchristian behavior " (whoring). But can you name anyone, just one person who was excommuicated for wiping out entire Jewish villages along the Rhine, when in some of those villages crusaders walked knee-high in blood?
Inquisition existed for almost four centuries, torturing and killing thousands of people around the globe --- has anybody been excommunicated for that? Of course not. Yes, we know that Papal Inquisition was much "milder" than hte Spanish one, but both were sanctified by the Varican, were they not?
Just look what the Church always did when its faith was perverted --- from Arianism to Albigensian massacres. All sorts of perversions were suppressed. If anti-Semitism was indeed a perversion, why is it the only perversion that has never been suppressed, never attempted to be suppressed --- not a person was as little as excommunicated for it? Why?
Was that a perversion of faith by the Pope himself when Jews were expelled from the Papal states merely for being Jewish? Please recall Isabella who, having taken Grenada from the Moors, expelled about 10% of her fellow Spaniards --- all Jews and all Roma (Gypsies). No expulsions are not forced traveling endeavors: great many of those people have died on high sees from the hands of pirates, hunger and decease. [ That's, incidentally how first Jews came to New York: their predecessors escaped all the way to the just discovered Brazil, but when Spain retook it, they had to flee Inquisition to Curacao; it is from there that some descendants arrived to New York ]. With the exception of two countries, nobody allowed the expelled to resetlle: the Turkish sultan actually invited them to come, thinking them to be an asset, and the Dutch agreed to tolerate the refugees.
Amidst such world-wide persecution and misery, did any of the Popes even speak up against this "perversion of faith."? Of course not: for these achievements, for the purity of her faith, Isabella became thenceforward known as Isabella the Catholic.
The consequences of this long history we see even in the United States where, unlike in Europe, Jews were not persecuted by the church and, despite considerable prejudice, no Jew lost his life in a pogrom. It is a deep Irony, that American Jews have a knee-jerk apprehension of religiously --- so much so that they are distrustful of their current best friends, fundamentalist and other Christians. Where do you think they got that apprehension from? Certainly not from American Christians themselves. They imported that apprehension and distrust from Europe, were they had been declared and persecuted as "Christ-killers" for 17 centuries. Memories are long, and Jews came to this country, as you will recall, just three-four generations prior to the present one.
So, with all due respect, please be honest with yourself.
I understand that it is painful for a person to discover unpleasant facts about members of his family. But that does not stop an honest person from facing the facts and applying his moral principles uniformly.
G-d bless the Pope for taking this long overdue step: it will only strengthen the unity of Christians and Jews, the unity we desperately need to fight the threats to our country: Muslim invasion and socialism.
