It could be said that there is not a lot of common ground between the Jehovah’s Witnesses and the Catholic Church. The Watchtower, the JW’s publication, is seldom complimentary about Catholic doctrine, and telling the Jehovah’s Witness person who knocks at your door “I’m a Roman Catholic” is often enough to put them right off their spiel. There seems to be a silent compact that “RCs” are too difficult to convert, so it’s a fool’s errand to persist. I am told they also immediately depart if told “I used to be a JW, but I apostatised.”
