Hi Trent
..." Doctrinal evolution means the discovery of more and more reasons through Scripture, Tradition and Reason to confirm belief that the original doctrines were correct. If scholars say the Church erred here and there, how can we today say what it teaches now is not erroneous"...

I understand why that concept is important to you. That concept is often expressed by many who post here.

But for me,  a limited view and limited understanding is not so much 'erroneous" or 'error' -- it is just incomplete. As time goes on and we learn more and are capable of understanding more, we add to our former knowledge and develop it. And explain why it was limited, and why it needs development.

The 'original doctrines' were sometimes limited. Not 'incorrect' – just not fully understood.

In my view, if we as a Christian Church can't grow and develop and admit our limitations of the past, we are not a Church worthy of consideration.
