Phil and realisticidealist, I'm kind of curious what you think of communion denial under any circumstances. My church is fine with communion to anyone who's a professing Christian. I really don't like the idea of cutting anyone off for some action as being "unworthy" or whatnot. I'm aware this rarely happens in the Catholic Church today but there are plenty that make a fuss about it, and then you have incidents like that priest in DC who denied it to a woman at her lesbian lover's funeral.
I'm sure your church doesn't believe in transubstantiation. A good Catholic receiving the Eucharist believes they are receiving what is literally the body and blood of Jesus Christ. Its what the whole Catholic mass is based around, and to take it flippantly and just give it out, especially to those who think its just some symbol or those defying the Lord by being in mortal sin would be to defile Jesus himself.
