I'm sorry. I can't tell if your post is meant to support mine or refute it. I don't know you enough to know whose "camp" you're in. So apologies in advance.
If you're augmenting what I said, I thank you. If not, and this is meant to refute what I said, how does it do so?
The statement in the last paragraph: "Nevertheless, God, who desires to call all peoples to himself in Christ and to communicate to them the fullness of his revelation and love, “does not fail to make himself present in many ways, not only to individuals, but also to entire peoples through their spiritual riches, of which their religions are the main and essential expression even when they contain ‘gaps, insufficiencies and errors'," points out that there are positives to other Christian denominations and even other religions, but there are "gaps, insufficiencies and errors." This does nothing to imply that the Catholic Church no longer considers itself the fullness of the Faith or the one, True Church of Christ.
Neither does anything in footnote 23.
Just trying to clarify. You left out: "Therefore, the sacred books of other religions, which in actual fact direct and nourish the existence of their followers, receive from the mystery of Christ the elements of goodness and grace which they contain."
