My Protestant friends get a little bit snooty when we don’t invite them to receive communion in the Catholic Church.
“But we practice open communion!” they cry with an air of wounded righteousness. “We invite anyone who loves and serves the Lord Jesus.”
So I ask them if they welcome Jehovah’s Witnesses, Moonies and Mormons. They all would profess to “love and serve the Lord Jesus.” For that matter Muslims claim “honor and venerate Jesus and Mary.” Why not invite them too?
In fact, all Christian groups practice closed communion. Catholics just admit it.
