mm, as you know, I am not a Roman Catholic nor am I an apologist for Roman Catholicism. I do not, however, find Roman Catholicism even remotely Mohammedan. I find much of protestantism distressingly so. As for JPII kissing a koran, well, it surprised me but then again I thought then and think now that he was a lousy theologian. Most Orthodox do and did. The quote from the Catechism is an example of the modernist, innovative theology which came out of the Vatican in his years. To say with absolute confidence that “the plan of salvation” (whatever that is) includes Mohammedans, at one level, states the obvious. The created purpose of all mankind is to become like God. This includes atheists, idolators, everyone. But I suspect this section 841 is going beyond that to place Mohammedanism in some special and elevated category. Stuff like this is why so many of us are very concerned about our hierarchs and their talks with the Latins. BXVI, on the other hand, for us is an entirely different matter. Can you imagine him kissing a koran?
Do you reduce Him to a mere prophet who needs validation by scripture?.
Read the verses at the link and see what Jesus has to say about Himself and His relation to Scripture.
John 5:39 You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me,
Yes, that is monotheism, and some vaguely Arian provenance.
