Wine at communion? A reflection

Today I did something I haven't done for nearly a year and a half: I took a chalice at Holy Communion, brought it to my lips, and drank from it. Don't worry: it wasn't wine. It was grape juice. What follows is a reflection from my own perspective: deacon, psychotherapist, lifelong participant in Protestant churches (Lutheran and Episcopal), and alcoholic. (I also studied sacramental theology about four years ago, and I read things, but don't expect the latest in the field here: this is just me sharing some of my experiences, thoughts, and feelings. Note also that I take to heart a line from page 103 of the Big Book of AA: "...we have stopped fighting anybody or anything. We have to!" This is not a manifesto, an argument, or the last word on anything. Take it or leave it.)
