Does it have anything to do with the Gospel?
Reformed Christianity is a Biblical perspective on the reign of the King - in other words, the euangellion, the good news of the King's march through history, that even conscripts such unworthy souls as you and me into His victorious army. That is to say, Reformed Christianity has everything to do with the gospel. A forthright faith in the God Who saves makes a man bold. Accept no substitutes!
(Parenthetically, the satanic cult of the BVM is the strongest barrier between me and Rome.)
