As a Catholic: Since each Mass has readings from the Old Testament, for those who have the time and inclination, I heartily recommend studying Judaism. While we Catholics touch on the Old Testament, there is a treasure trove of insights and information available that enriches faith and therefore one's life.I've been wondering whether embracing Judaism is the default position, having been raised as a Catholic Christian, leaving Catholicism for Protestantism, and then seeing the rise of such assholes as the "Christian" right who simply trash the Christian faith.
Non-Catholic Christians are certainly welcome to correct/disagree with me--I see many of these denominations as a streamlined version of Catholicism with Catholics using the streamlined version of Judaism within the Catholic faith. Personally, I like in depth everything!
I think the Latin Masses and choirs are great, I go with Catholic friends a few times a year; not that many still doing the Latin masses except on special occasions around here, though.. On the other hand, I think the Baptists have the right approach theologically.
