I loved RCIA but it’s hard to compare the two. LDS focuses on the scriptures in seminary (one year is OT, one is NT, etc) and not so much on what they believe although it is touched on and probably is significantly covered when the go over Doctrine and Covenants (I left the church before that seminary year). But LDS seminaryis a 1 hour class every weekday during the school year, and that is significant- 5 hours a week vs. the about 1-1/2 hr RCIA class once a week. But RCIA focused more on what we, as Catholics, believe. Bible study is separate. I think that is really important though- had I truly understood what it is Mormons believe, I probably would never have joined the church. I do think RCIA could be more comprehensive, however. For example, what we never learned in RCIA was what you do after you’re baptized/confirmed. We did have one class on the Rosary/Chaplets but we never went over Adoration, or Scapulars, or Consecration (as a layperson), or different ways to serve your Parish or community, or any of the other myriad things that Catholics participate in to deepen their faith and come closer to Christ and live the Gospel. I guess we were supposed to have something called “Mystagogia” which was to learn more after RCIA was over, but our Faith Formation leader became a Permanent Deacon right after RCIA wrapped up and he just got too busy I guess.
