Poche, how long have you been on this website, and read all the BOD/BOB and Modernist presentations, and have yet to pick up on how the Baltimore Catechism was put together by the liberals of the American Hierarchy, at a time when they were not just (beginning to be?) influenced by Masonry, but also in the business of getting along with the non-Catholics of the United States, and making salvation a non-challenge to those souls? They would not tell them there is no salvation outside the Catholic Church. And then, even if they mentioned that, or the phrase "One True Church," they would soften the requirements with Baptism of Desire and Baptism of Blood.
I know people who were never taught BOB/BOD - and catechisms other than the Baltimore which NEVER mentions it. The catechisms prior to the Baltimore catechism in this country did not mention it.
What do you think Pope Leo's slap down of the U.S. Hierarchy via his condemnation of Americanism was all about? In it he stated his alarm at the liberalism here, and that Catholicism as taught in America had better be the same as that taught in the rest of the world.
