David Gibson tells the tale of efforts by the Episcopal Church in Atlanta to overturn the condemnation of Pelagius rendered by the Council of Carthage. Pelagius denied the doctrine of Original Sin which has long been considered the one doctrine of the Church that required no faith, only observation, for its confirmation.
Original Sin is the most obvious part of the human inheritance. It is our birthright you might say. Felix culpa. Shame on these folks in Atlanta who wish to rob us of it.
