What Do Catholics Believe About The Pope?

Roman Catholics believe the Pope is the "Vicar of Christ" on earth.  In other words they believe the Pope is the representative of Christ on earth.  They see the Pope as the head of the church on earth.  Catholics believe the Apostle Peter was the first pope and the ones that followed him are his successors.  

Roman Catholics teach that the Pope is infallible when he speaks "ex cathedra" or from the chair.  This means he cannot be wrong when he speaks in his official capacity as Pope.  Catholics often refer to him as the Holy Father and the term pope actually means father.  

Roman Catholics reject the Protestant doctrine of Sola Scriptura (Scripture Alone as the ultimate authority).  They believe the authority resides in the Magisterium of the Church, that is the Pope and the bishops.  Catholics believe Scripture can only be interpreted authentically by the Magisterium of the Church.
