The pope (Latin: papa, from Ancient Greek: πάππας, romanized: páppas, lit. 'father') is the bishop of Rome and the visible head[a] of the worldwide Catholic Church. He is also known as the supreme pontiff, Roman pontiff, or sovereign pontiff. From the eighth century until 1870, the pope was the sovereign or head of state of the Papal States, and since 1929 of the much smaller Vatican City state.From a Catholic viewpoint, the primacy of the bishop of Rome is largely derived from his role as the apostolic successor to Saint Peter, to whom primacy was conferred by Jesus, who gave Peter the Keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the Church would be built. The reigning pope is Francis, who was elected on 13 March 2013.

A conference is a meeting, often lasting a few days, which is organized on a particular subject, or to bring together people who have a common interest. Conferences can be used as a form of group decision-making, although discussion, not always decisions, is the primary purpose of conferences. The term derives from the word confer.
