Yep. Liberals have captured the religious field in the same way that they have captured politics, media and education. They have obtained ownership and authorship in the press.
Some time ago someone who went through RCIA 'classes' asked me for a good short source book on what Catholics believe (sad isn't it after RCIA) - not as long and scholarly as the Catechism. I asked Priests and came up empty. The closest I came was a book 'Catholicism for Dummies'. But even that was mostly what Catholics do rather than 'this is what Catholics believe'. Years ago my wife got kicked out from CCD teaching because she tried to go beyond "Jesus loves me and I love Jesus".
Still looking if anyone has a lead. thanks,
A highly recommended Catechism (by those more qualified than me) is the Baltimore Catechism. It was written at the Baltimore Council in 1895 (give or take a few years). It contains a list of questions and answers that are quite straightforward and provides Scriptural citations to support the doctrine. (The numbers - No. 1, No. 2, No. 3 - refer to level of detail and depth in the answers.) They can just read the question and short answer or read the more detailed explanation.
