It's an odd world when even the Lutherans are more Catholic and traditional than the Roman Catholic Church.
They always have been, that's why they were protesting in the first place. Most Lutherans consider themselves Evangelical Catholics.
I personally think if you read the Augsburg Confession and read the church fathers it's all fully acceptable doctrine that was preached in the early church. Maybe not universally but in those days there were a wide range of theological differences.
It won't ever happen but I think if the Pope gave up his Primacy and Infallibility and Rome and the East could be open to some theological differences the Roman Catholics, EO, OO, Anglicans, and Lutherans could unite.
