LOL - I see that the Greek Orthodox church I'm visiting is no different than other churches I've been to, in that if you happen to mention to someone that you have a talent for _____ (fill in the blank), word will get around and you will then be recruited for something within the church

. (And, YES, one should want to use their talents for the Lord!)
We had a special liturgy for Thanksgiving this week; the attendance was small, and we only had 2 choir members. Someone (who knows I sing) suggested I go and help out the other two folks who were singing, but I didn't think it was my place since I have yet to join the church and right now I'm sort of "unofficially" a catechumen. I found it neat that I was encouraged to join in with the choir, but just thought I should run that by Father first. Maybe what a catechumen is allow to do/not do, as far as participation in a local parish varies from church to church . . .don't know.
