of Christ Church and were until recently held only by Anglican priests. At Durham, the canon professorships are the Van Mildert Professor of Divinity, the holder of which must be an Anglican priest, and the Michael Ramsey Professor of Anglican Studies, who must be Anglican but did not have to be ordained. Historically, the chair in Greek at the university was also a canon professorship. This canonry was transferred to the Lightfoot Professor of Divinity in 1940. The Lightfoot professorship was attached to the canonry until 1985, when the non-Anglican James Dunn was appointed. Minor canons Minor canons are those clergy who are members of the foundation of a cathedral or collegiate establishment. They take part in the daily services. They have sometimes formed a distinct corporation as at St Paul's Cathedral, London. In St Patrick's Cathedral, Dublin, they are distinct from, and rank before, the Vicars Choral. The two groups overlap however; the two senior vicars, the Dean's Vicar and the Succentor, are also the two senior Minor Canons. Some Minor Canons do sit with, but are not voting members of, the Chapter. Although at present Minor Canons are generally more junior clergy this is a recent development. Within living memory such offices were often freehold and were held by clergy of great distinction and seniority. Canons regular Canons regular are the members of certain religious orders in the Roman Catholic Church (not to be confused with clerics regular), composed of priests and some choir canons who live in community, with lay brothers. There is a variety of congregations of canons, some of which are part of the Confederation of Canons Regular of St. Augustine: Canons Regular of the Lateran or St. Saviour, which seems to date back to Pope Alexander II (1063) Order of the Canons Regular of Premontre; Norbertines founded by St. Norbert (1120) Order of the Holy Cross (Canons Regular) founded in Portugal in 1131 and re-founded in 1977 Canons Regular of the Order of the Holy Cross (the Crosiers), founded at Clair-lieu, near Huy, in Belgium, in 1211 Swiss Congregation of Canons Regular of Saint Maurice of Agaune Gilbertine Order, a solely English order of canons regular, driven to extinction under King Henry VIII Canons Regular of the Immaculate Conception, a congregation of Canons Regular founded in France in 1871 Canons Regular of St. John Cantius, founded in 1998 by Fr.
