Vatican 2 was intended as an 'aggornimiento' – an effort to bring Catholics to learn to live in the world we actually inhabit. So it was a start to get us away from a Medieval, and post-reformation, mind-set. We are still working at it.

Meanwhile it becomes apparent that we need to tackle a 'dogmatic' Council. 

We claim to base our theology on Scripture and Revelation. But our understanding and interpretation of Scripture has developed. We have not yet worked our Scriptural understanding into our Theology.

The most obvious example is our theology of 'original sin' and how we think and speak of it. 
Scripturally, we say that God inspired the creation stories of Genesis to be written as a myth literary form. What are the theological implications of that? If  'Adam and Eve' are not actual, real, historical people, then – obviously – there was no actual 'original sin' to be 'inherited' and passed to humanity.

Dare we tackle getting our Scripture & Theology back in union?
