I remember a time when I thought that when people were talking about Maundy Thursday, it was because they could't make up their minds what day it was!
I suppose my answer is much the same as Mooh's except Communion for me is probably a rather different affair than his. I have very little use for organized religion. I feel that such things are the pitiful inventions of Man in an attempt to find a "correct" pathway to the higher being. But I will defend to the death, your right to pursue whatever path you have chosen.
I never feel any closer to the guiding forces in my life than when I am paddling a canoe down a river, walking in the forest, listening to beautiful (to me) music, or watching children at play. For me, those moments are as holy as anything could ever be.
