It seems to me your academic argument is that the CCC, as well as the God of Abraham, Isaac, and Jacob deals in religions and not people as the subject.
CCC843 says "The Catholic Church recognizes in other religions". There is no switching of gears as if we're going from talking about a people and now religions.
You left out 842, whose subject is all nations. Afterward the truths and errors of religions in the context of salvation is discussed.
BTW, while we're at it, this heading is CCC839 "Those who have not yet received the Gospel are related to the People of God in various ways." The Jews HAVE received the Gospel, for the most part they've rejected it. This whole section needs a traditional rewrite. Precision doesn't seem to be high on the list of goals this time around.
I'm not shocked that this ended up at the Jews' door, so to speak. I think I now understand how your reasoning led you to publicly deny the Catechism of the Catholic Church.
Please, enlighten us with your newfound understanding.
... Count me in, too!
