Therefore, until the differences between Catholics and Protestants are healed, a real “intercommunion” cannot take place. Moreover, out of respect for the differences in belief, a Catholic is obliged to refrain from receiving communion at a Protestant service, and likewise, Protestants, at a Catholic Mass. I remember once I participated at the funeral of a friend at a Protestant church, which included a communion service. The minister invited everyone to receive communion. I refrained out of respect for their beliefs and my own: I did not fully accept all the beliefs or practices of their particular denomination, nor did those members accept all that the Roman Catholic Church believed. Therefore, to receive communion would be to state, “I am in communion with them,” when I was not. Worse yet, had I partaken, I would have received something sacred which should bind me as part of their communion — at least from a Catholic perspective — when in fact I have never participated in one of their services since then.
