What do we make of the bulls, councils, decrees and encyclicals prior to the Second Vatican Council which are contradicted by those afterwards? Do we presume the popes, bishops and theologians responsible for them, which includes some of the Church's greatest saints, were a) erroneous, b) evil, c) ignorant, d) insane or e) two or more of the above?

While doctrines develop they can not be contradicted or destroyed, particularly when the magisterium acts in the name of Christ, the Wisdom and Word of God, and is guided by the Holy Ghost, the Spirit of truth who teaches all things.
