Sorry, but your knowledge of church history is a bust!  In the New Testament, especially Paul's letters, shows us that crisis,  errors and yes, human sin have been part of the church's history from the beginning.  The Paschal Mystery can work forgiveness and reconciliation even in the midst of confusion, and scandals.  In the early Christian communities, UNITY rather than UNIFORMITY was the ideal.  The work of ministry was more important than titles and doctrines.

What gave unity to these diverse local communities was their faith in the PERSON of Jesus and the ideal of Christian life as "faith working through love" [Galatians 5:6].  The approach to moral theology [doctrines] is less concerned with specific actions or teaching as it is with three fundamental question that pertain to human existence:  Who am I? What is my goal in life?  How do I get there?
