Your initial comment was along the lines of political alliances. As far as preaching The Gospel it seems that a lot of RC posters have trouble explaining it, so maybe they aren't doing a real hot job of it.
Are you certain that you are not confusing your own interpretation of the Gospel with the Gospel that the Church has preserved and preached for nearly two thousand years?
You can walk into any Christian bookstore in the world and find volumes by various authors each giving their interpretation of every passage in the Bible. Eventually, you might find one that you agree with. On what basis is this interpretation any more valid than the one that the Church has taught for almost two thousand years?
