Just an explanation. This prayer was in the Old Rite, and BXVI rewrote it so it wouldn’t reflect the anti-Semitism that was a feature of its place of origin (Carolingian France, source of what is known as the Franco-Roman Rite that is the basis, even after Trent, of the Old Rite mass).
That said, I don’t know why liberal Jews would care about this - it’s not anti-Semitic, but prays for their acceptance of the Messiah, which is logical in a Catholic prayer. If we want to start attacking prayers, how about the Jewish prayer where you thank God you weren’t born a woman? Curiously enough, lefty feminists seem to have missed this one.
It all depends on your target, in other words.
“so it wouldn’t reflect the anti-Semitism that was a feature of its place of origin”
Was it anti-semitic? Many of the Jews - in regard to Jesus - were “faithless” and some were even “treacherous”.
So are we saying that the Catholic Church used an “anti-Semitic” prayer for hundreds of years?
Benedict is simply following Paul. Which means that the Germans are talking through their ...hats.
