Oh, and in a Catholic Church, Communion, Lord's Supper, Eucharist, Holy Sacrifice of the Mass, are all the same thing. The priest was wrong. I'll try to find the Canon Law for you, after I go to Mass this evening.
Well he was presiding over a non denominational service that was being held in a Catholic church if that makes a difference.
As to Catholic Canon Law, I'll take your word for it. I just know that the priest said it was OK to come take the sacraments as long as you believed in Jesus as Savior and Lord.
