I asked you to show me somewhere where a Catholic was teaching what you claim that clause to be teaching. There are 3 sections prior in the section of Vatican II that precede the clause that would dissuade anyone reading it in context from getting that impression since they are excluded from membership in the church.
All the Catholics are saying by saying Catholics and Muslims adore the same God is an affirmation that Islam is Abrahamic, basically accepting the claim that Muhammad is a son of Kedar. It's an incorrect statement that is very much in error, but it does not have the implications that you are trying to smear it with. Catholics are well aware that Muslims don't recognize the Trinity, and Catholics very much affirm the Trinity.
So you're welcome to show me somewhere a Catholic is getting from that clause what you claim it means, where they are teaching what you claim it means. Until then my impression that you're unfairly smearing them with an out of context statement remains.
