As long as it's not violating the Ecumenical rule - I will throw out that Fundamentalists that I was aware of (20 years ago) scorned Evangelicals almost as much as they scorned the Catholic/Orthodox.
Some Catholics lump evangelical and fundamentalists together under the broad term of Protestant. Most fundamentalists would call themselves evangelical in terms of their agreement with Christ’s command that Christians go out tinto the byways of the world and “evangelize” which some would also call prosletize(if one were casting aspersions).
So that is why I called for more clarification of definitions. I’ve read of a lot of Episcopalians joining the Catholic church with the terms both protestant and or evangelical being applied to them. I have not read of a lot of Assembly of God members leaving and joining the Catholic Church(in deed they are experiencing member growth supposedly documented by the same “neilsen” service that documents Catholic conversions, who ever documents these things). Yet Assembly of God members would call themselves evangelical and fundamentalist Bible believing orthodox Christians. So who has the authority to actually define what an evangelical is?
If one were to stay true to the socialized accepted meaning of the term “fundamentalist”; Roman Catholic believers believing that the Vatican is the only Christian authority on Earth and shunning all else who believe differently, might be described as “fundamentalist” in their view of their church and its practises!
