I am well aware of Catholic beliefs.  And I know and teach HOW they developed.  The fact that Jesus came was NOT to free us from any Original Sin.  That concept came largely from Augustine.  Because he was one of the most brilliant minds of the Western Church, his thinking was adopted as a teaching of the Church.

The official church knows very well that the universe was created in billions of years and our own planet in about 4.6 billion years.  THEY know that there was no Original Sin as well.  But their whole theological house of cards is dependent upon this concept of 'the Fall of the Human Race'----that the church would have to start from scratch all over again with re-doing basic theology.  So they just keep on with this 'mythic tale'.

I certainly do believe that God began Creation.  But it did not occur as the first chapters of Genesis have it.  Of course, Genesis was written in the pre-scientific era.  The official church needs to confront this fact.
