The Church is a closely organised and united society. It is made up of the hierarchy and the faithful. All members obey the Pope, the Vicar of Christ. The Pope shouldn’t rule as a proud king, but as a Father, the representative of God; as a good Shepherd, caring for each member of the great flock. The obedience of the faithful is responsible for the wonderful unity among the members of the Church throughout the world. There are about 1.2 billion Catholics, all submitting to the hierarchy, at the head of which is the Pope.
The hierarchy is the organisation of the ruling powers of the Church in levels or grades, just like in the army. The Pope is the visible head of the Church – he is commander-in-chief of this army. He has jurisdiction and supreme and sovereign power and authority over the entire Church.
