Maybe I’ll be the lone voice to say that I don’t think being an “expert Catholic” is a prerequisite for being a sponsor.
I think the first requirement is to be someone who loves his or her faith and wants to help someone else on the journey into the Church. You should be someone who loves the sacraments, someone who loves the Church, someone who prays, and someone who can be a supportive mentor and friend to a catechumen or candidate.
Catechumens have catechists and if they have questions, the catechists are good sources for answers. The kinds of questions a sponsor should be able to answer would be things like “Why are you Catholic?” and “Why do you pray?”
If all you want is “facts,” then buy yourself a copy of Catholicism for Dummies and start brushing up. Being a sponsor means making a serious commitment to helping someone else on the journey.
No - you aren’t alone! I was thinking the same thing. None of us are ‘perfect’ Catholics.
We are all on a spiritual journey and we have a duty to mentor younger Catholics as they grow in their faith.
Honestly, my sponsor was a “sponsor in name” only. She was thrilled that there were no meetings to attend and she had a long standing vacation planned for Easter (and Easter Vigil.) So, I had a stand-in on the big day (who, looking back, I should have asked to be my sponsor in the first place.)
I like to think that I could do better than be a “sponsor in name only”. I almost think that I should have let the parish find a volunteer to be my sponsor, but I wanted it to be someone I knew - even remotely. Not a completely random stranger.
Just be yourself and if God wants you to be a RCIA sponsor, then it will eventually happen.
Heck, even I volunteered to be a sponsor at my new parish, mostly because I know what it’s like to go through the process and know what it’s like to struggle with faith and try to decide whether Catholicism is really for me.
I really doubt that the RCIA director will ever call me, but I’m open to the possibility of helping someone with their conversion process because I think that it’s wonderful, that in this day and age, people would still want to be Catholic. It’s important to support potential converts.
