Just to clarify...are you asserting that Christ established the Roman Catholic Church - excluding all other Christian assemblies - from the start?
When Christ established HIS CHURCH, it was ONE. Not 35,000.
The Bible is a Catholic document, handed on to the world By the inspiration of the Holy Ghost ON A CATHOLIC COUNCIL in 398. If the Church is wrong now, it was wrong then. The Church is the infallable Teacher, and the Perfect Body of Christ,(containing sinners) Christ established the Church, He IS God, God doesnt make mistakes.
There is one Catholic Faith, as God is One, there are tens of thousands of non catholics taking bits and peices of the bible to carve out whatever little niche helps them cope with who they are. If individuals can define the faith for them selves then Christ and his Word becomes babble.
