Chapter XI. Infallibility Of The Popes. 133 "we define that the Roman Pontiff is the successor of the Blessed Peter, Prince of the Apostles, and the true Vicar of Christ, the Head of the whole Church, the Father and Doctor of all Christians, and we declare that to him, in the person of Blessed Peter, was given, by Jesus Christ our Savior, full power to feed, rule and govern the universal Church." The Pope is here called the true Vicar or representative of Christ in this lower kingdom of His Church militant — that is, the Pope is the organ of our Savior, and speaks His sentiments in faith and morals. But if the Pope erred in faith and morals he would no longer be Christ's Vicar and true representative. Our minister in England, for instance, would not truly represent our Government if he was not the organ of its sentiments. The Roman Pontiff is called the Head of the whole Church — that is, the visible Head. Now the Church, which is the Body of Christ, is infallible. It is, as St. Paul says, "without spot or wrinkle, or any such thing." But how can you suppose an infallible body with a fallible head? How can an erring head conduct a body in the unerring ways of truth and justice? He is declared by the same Council to be the Father and Doctor of all Christians. How can you expect an unerring family under an erring Father? The Pope is called the universal teacher [130] or doctor. Teacher of what? Of truth, not of error. Error is to the mind what poison is to the body. You do not call poison food; neither can you call error doctrine. The Pope, as universal teacher, must always give to the faithful not the poisonous food of error, but the sound aliment of pure doctrine. In fine, the Pope is also styled the Chief Pilot of the Church. It was not without a mysterious significance that our Lord entered Peter's bark instead of that of any of the other Apostles. This bark, our Lord has pledged Himself, shall never sink nor depart from her true course. How can you imagine a stormproof, never-varying bark under the charge of a fallible Pilot? But did not the Vatican Council in promulgating the definition
