The founding of the cathedral at Exeter, dedicated to Saint Peter, dates from 1050, when the seat of the bishop of Devon and Cornwall was transferred from Crediton because of a fear of sea-raids. In 1107, William Warelwast, a nephew of William the Conqueror, was appointed to the see, and this was the catalyst for the building of a new cathedral in the Norman style. Its official foundation was in 1133.

Martin Luther (November 10, 1483 - February 18, 1546) was a German monk, theologian, university professor, Father of Protestantism, and church reformer whose ideas influenced the Protestant Reformation and changed the course of Western civilization. Luther's theology challenged the authority of the papacy by holding that the Bible is the only infallible source of religious authority and that all baptized Christians under Jesus are a universal priesthood. According to Luther, salvation is a free gift of God, received only by true repentance and faith in Jesus as the Messiah, a faith given by God and unmediated by the church.

In addition to being a parish church in the Diocese of Ely, it is the University Church for the University of Cambridge. As such it has a minor role in the University's legislation: for example, University Officers must live within 20 miles of Great St. Mary's, and undergraduates within three. The church also hosts University Sermons, and houses the University Organ and the University Clock. The latter chimes the Cambridge Chimes which were later used by the clock tower of the Houses of Parliament ("Big Ben").

Peter Jan Beckx (February 8, 1795, Sichem, Belgium - March 4, 1887, Rome, Italy) was a Belgian Jesuit, elected 22nd Superior-General of the Society of Jesus. The Duke and Duchess of Anhalt-Köthen converted to Catholicism in 1825 and asked for a Jesuit chaplain. Beckx was appointed to this duty, and went to live in Köthen. By giving classes to children in his own house, building a little church and organizing spiritual activities he brought many people back to the Catholic faith. By 1883 - 88 years old and already 30 in office — Peter Beckx was an infirm. On his own accord he called a General Congregation in order that a 'Vicar General with rights of succession' be given him. General Congregation XXIII met in 1883, in Rome, and the 24 September Anton Anderledy, a Swiss Jesuit priest, was elected. Beckx, though remaining in title the 'Superior General' in effect abdicated his charge entirely. He died four years later at the age of ninety-two.
