lets use the process of elimination...
.....you have got to be kidding....'Process of elimination' to determine if the churches of rome were catholic or not?????? and your response is avoidng the proof.
The earliest post-apostolic document written by the Roman church, First Clement, contradicts the teachings of today's Roman Catholic Church. It teaches salvation through faith alone,... for example (First Clement, 32).
The Shepherd of Hermas, an early post-apostolic document written by a member of the Roman church, teaches the doctrine of limited penance, which Catholics reject.
Some of the early Roman bishops, such as Leo I, denied that Mary was immaculately conceived.
The earliest generations of Roman Christians were not Roman Catholics.
NEVER in the bible does it say faith alone..In fact somewhere in James, say 3:18 but some men will say thou have faith and I have works, show me thy faith without works , and I will show you my faith by my works. 3:22 seest thou that faith did cooperate with his works and by works faith was made perfect.
would it be that simply saying "I believe" with no responsibility whatsoever for our behavior would gain us eternal salvation??? I think that it is harder than that, At least I hope so or all our efforts at compassion,charity , consideration,love, etc. would be all for naught. Jesus saved us all so we have no responsikbility whatsoever for our salvation...nice thought but wrong.
if the early Roman Christians weren't Catholic...what were they, There was nothing else.....real old Lutherans???
