They are kinda like that. If you aren’t born in the Catholic Church, it’s kind of a pain to get in. You have to do classes for at least a year and have someone sponsor you. It makes sense - they take their belief seriously and want to make sure that people joining know what they’re getting into
Yeah. If you go through the Rite of Christian Initiation for Adults (RCIA), you get baptized, given communion, and get confirmed all at the same time on Easter. Having a sponsor is part of the sacrament of confirmation.
At least that’s the way my church growing up did it. I’m sure there are exceptions for extenuating circumstances and differences across countries.
