Is a Greek Orthodox Mass Valid?
A close friend invited us to attend a wedding at a Greek Orthodox Church, can we receive communion as Catholics and will the Mass be a valid one?
Yes, you can receive Communion if you go to this wedding, but only with the bishop’s prior permission. The biggest problem here is that you cannot rely on a Greek Orthodox Church to be a truly Greek Orthodox Church. In other words, many Orthodox Churches today are merely off shoots of the schismatic Orthodox churches. Before you bother to ask your bishop’s permission, you need to make sure that this is a genuine Greek Orthodox Church. By the way, it would indeed be a valid mass.
