Where to receive communion

I asked the Chief Rabbi today if Catholics can receive communion in other (Protestant) churches. The answer was a resounding NO. Felt better. It was really bothering me. If you followed this blog you will have noticed that last week my fellow friends drowned me out telling me that it was no big thing to receive communion somewhere else in a non-Catholic church. The Deacon also thought this was no problem. I started to think that I was wrong and the whole thing just bothered me tremendously. Well, I was right after all. Felt so much better.
