Are RCIA converts required to believe all doctrines?

I’m helping in an RCIA class. One of the questions was do I have to believe all this stuff before I become Catholic? Someone else in the class(who is already Catholic) said to her, “I don’t believe all that stuff and I’m Catholic.” I was floored. I spoke with the person after class but didn’t have much luck. It seems to me that all doctrine would need to believed (but not understood) before becoming Catholic. (cf CCC 88 and CCC 2087-2089) Am I totally off base or on the right track? (Does Cannon Law address this?)

Dear Larium,

Yes indeed, they are expected to believe all the doctrines of the Catholic Church. Aren’t they preparing to become Catholics? Being a Catholic means believing what Catholics believe. Maybe that person isn’t ready for the RCIA yet. And the Catholic who agreed, needs to learn the faith.
