heh... I use it for my 5th, 3rd and 1st grade children. I make them memorize the questions and answers too. Just like I make them memorize multiplication tables, the periodic table of elements, parts of speech, presidents of the US (monarchs of England, emperors of Rome... lol), etc. Lists, lists, lists!
The Baltimore Catechism is a great foundational springboard and I haven't found anything better for the instruction of children, even/especially the new CCC. But yes, if my kids are still dependent on the formulas of the catechism they learned as children when they're adults there's gonna be a problem.
OK, but as I recall the Baltimore Catechism, at least they'll have the vocabulary to progress! Hard words? Tough -- here's the glossary in every chapter! ;-)
I first learned form it too. My point was that it is a primer, not an authoritative source. Its purpose was to get Catholics to the point of intelligently asking "Why?" in the context of Catholic dogma. Those who complete their knowledge of the Catholic dogma with a cursory knowledge of the Baltimore Catechism are poorly Catechized. Those who cite it as authoritative simply look foolish.
