From Metmom's post earlier:
From the Catechism:
841 The Church's relationship with the Muslims. "The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind's judge on the last day."330
Pity we wasted so much time and effort on all those Crusades.
As for that passage from the Catechism, I've never encountered it in my Bishop Morrow Catechism.
