The Bible is one of two essential works, IMHO, the other being the Catechism of the Roman Catholic Church, brought out in a magisterial new addition in the early '90s by Joseph Cardinal Ratzinger, who is now Pope Benedict XVI. As Prefect of the Congregation for the Doctrine of the Faith, Cardinal Ratzinger presided over the Magisterium, which is of course biblically based.
My confession of the Faith is summed up in the Nicene Creed. What exactly are we arguing about here, Kolokotronis?
