To answer your questions:
We usually say various words for G-d, using a combination of names and titles. Since our prayers are in Hebrew and all branches learn them that way or have the Hebrew available as a transliteration, it is easy to find a word, title or substitute for this or that. But to some degree you are going to use one word or name more than others. A lot of Jews say “HaShem” when referring to G-d. “HaShem” is Hebrew for “The Name.” That’s pretty easy.
As for repetition in prayer, I have no more to offer. I only know that the repetition in Matthew is describe by Jesus as the type practiced by Gentiles, so regardless of our personal views it obviously meant something definitive that Jesus could point to. That is up to debate among Christians, for as I said I can only report what scholars say. I have no personal opinions about this, actually.
And for what it is worth, the Jewish texts are products of their time. People viewed conquering of their enemies as signs that they were blessed from Heaven. Ancient Jews attributed this to G-d, and wrongly so. Remember unlike Christians, Jews are not bound to accept the written text as literal or to avoid looking at it critically. We once used to only say that HaShem was the G-d of Abraham, but now we say the G-d of Abraham and Sarah. We recognize our people have been wrong and change things as time moves on. You can’t stick by ancient texts that offer guidance for times long gone. But you can try to find the good in anything and adopt what works for you.
And on Jesus Christ: I think that a few agnostic and atheists that come from a Christian background have a hard time separating the importance of Jesus to the G-d issue in Judaism (not to mention Christians themselves). Just like JWs don’t go around wondering what new publications and pronouncements the Mormons are making or what the latest encyclical of the Pope means, Jews don’t go around thinking about what they don’t believe about Jesus. It’s like that joke where one man from Canada sits across from an American at a truck stop restaurant, and the guy from Canada asks: “What do you Americans really think about us Canadians?” To which the American replies: “We don’t.”
So the fact that Jesus may have been a prophet doesn’t mean that I also have to think he is the Messiah. If he was a true prophet, I can live with that. But I also believe that how the Christians interpreted Jesus of Nazareth was incorrect. So the conclusions about Jesus are different. The other stuff, I don’t think about. I don’t even believe in a personal Messiah as being the fulfillment of Jewish expectations. Many Jews are so past that. So the Jesus-issue doesn't even come up for consideration normally.
And no, the Jewish Annotated New Testament, though available for Kindle as well as in hard copy form from Amazon, is not a light read. It is the entire NRSV New Testament text with footnotes, commentary, and study articles from Jewish sources regarding the material. It is a best seller and often hard to get in hard copy from, so you better get that Kindle app if you want to read it.
Lastly, no. I don’t blame Christians as a whole for the Holocaust. I stated “Christian nations.” The actual expression is “Christendom,” but because JWs have screwed that up as well too so that even ex-JWs use “Christendom” to mean “false Christian religions,” I was forced to use a term that I believe many ex-JWs are still not familiar with. “Christendom” actually refers to the secular bloc of nations in Europe and Asia that once had kings who exercised their rights as such by Church authority. The nations were also legally Christian or considered themselves by law as such. Germany was a member of Christendom until Christendom crumbled with the passing of the two world wars. Christendom no longer exists as these nations all claim to be secular and those that don’t, well the whole idea is over now. My blame was on these so-called members of Christendom, the nations that either did something or failed to do something. But I can’t call to blame people who weren’t alive then or Christians as a whole.
