Commemorations are a type of religious observance in the many Churches of the Anglican Communion, including the Church of England. They are the least significant type of observance, the others being Principal Feasts, Principal Holy Days, Festivals, and Lesser Festivals. Whereas Principal Feasts must be celebrated, it is not obligatory to observe Commemorations. They are always attached to a calendar date, and are not observed if they fall on a Sunday, in Holy Week, or in Easter Week. In Common Worship Commemorations are not provided with collects or indications of liturgical colour. However, they may be celebrated as Lesser Festivals if local pastoral conditions suggest it.

n Christian belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term saint depends on the context and denomination. In Catholic, Eastern Orthodox, Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but a selected few are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval.In many Protestant denominations saint refers broadly to any holy Christian, without special recognition or selection.

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.
