Just a note -Haaaaaaaaa! What a joke. Catholicism, or Universalism was around from the very beginning. There was but one Universal (Catholic) Christian Church from the get go.
Many earlier non-Catholic (churches that do not belong to the Roman Catholic or Eastern Orthodox Church) speak of belonging to the catholic church (used to speak of the body of Christ rather than the assembly). For example, if you read 19th century Baptist writings you will see this on occasion.
I think James point was that the Roman Catholic Church did not exist until the 4th century.
