This is the greatest short explanation of Christianity ever produced by fallible men.
It is English Calvinism / Presbyterianism at its best! It was the theology that swept Catholicism out of England. It was the theology that was brought to America by the Pilgrims, and eventually became the foundation of our representative government. Scripture Alone, Predestination, Justification, and much more are fully explained. Nothing is held back, even the Pope of the Roman Catholic Church is correctly identifed to be anti-christ in chapter 25, section 6, of the Westminster Confession Faith. Sola Fide!
