"Many"? You are "sure"? Where does the Catholic Church teach that Baptism of Desire is something that happens often and where does the Catholic Church teach that we can be sure and hope that there are many people ....in non-Catholic religions.... that will be saved by it? Father, with all due respect, you have been drinking the Vatican II Kool-Aid for too long.
There are about six billion non-Catholics in the world. If 1% of them have received Baptism of desire, how many is that?
If you claim that that isn’t “many,” then how about inviting them all to dinner some evening soon?
