The only part I can remember not taking part in was the wafer thing - but I didn't take part because I had no desire to.

If "the wafer thing" is how you think of it, then it would be better if you didn't participate. Practicing Catholicism isn't like signing up with Carnival Cruises for a five-day getaway to St. Bart's.

I don't remember the priest saying that you had to be Catholic to do it. How does this work in practice - does the priest ask people who is Catholic before certain services begin?

No. You're catechized and baptized into the faith if you're an adult, and you are further catechized, confessed, shriven, and given a penance of prayers to perform. Once this is accomplished, you may then share in Holy Communion. Baptism, confession, and Holy Communion are the three principal sacraments of the Roman Catholic Church, and they don't play around with them.

Thanks for the info. I meant no disrespect by saying the "wafer thing" - I just couldn't remember what it was called at the time of the post. My question still applies though - my post was in response to someone who said that the Catholic church didn't qualify as a public accomodation since not everyone can take part in all of the services. You seem to be saying that only Catholics can take part in Holy Communion, Baptism and confession. I'm still curious as to how this works in practice. If the priest doesn't ask people who aren't Catholic to participate, how does he know that only Catholics are taking part?
