Bonum ex integra causa, malum ex quocumque defectu is Latin for “Goodness comes from a complete cause, evil from any defect whatsoever.”>You may remember the free catechetical series I produced called Catechism of Pius X (CPX) which is a YouTube playlist at that link. If you’re converting to Apostolic Catholicism (either from Protestantism or modernism) I highly suggest you watch that series. On CPX, I explained the traditional Catholic faith in about 20 hours. Also online, I’m currently teaching the Roman Catechism of Trent (RCT.) It is also a YouTube playlist at that link. Unlike CPX, we have not yet come to the end of RCT.>As you can imagine, I very much prefer the CPX and the RCT to the new Catechism of the Catholic Church (CCC) partly because the CCC has a few errors. One of these errors is claiming the death penalty is never permitted” which obviously goes against Scripture (cf Rom 13.) But today is not about the death penalty. All I mean to assert in this paragraph is this: Anytime I quote the CCC, it’s essentially an a fortiori argument. For example: “If even the CCC maintains the traditional teaching of the Catholic Church on topics x, y, z, so also should modernists accept it with no problem.”
