what is a canon priest in the catholic church
Canon (priest) Originally, a canon was a cleric living with others in a clergy house or, later, in one of the houses within the precinct of or close to a cathedral and conducting his life according to the orders or rules of the church. This way of life grew common (and is first documented) in the eighth century. In the eleventh century, some churches required clergy thus living together to adopt the rule first proposed by Saint Augustine that they renounce private wealth. Those who embraced this change were known as Augustinians or Canons Regular, whilst those who did not were known as secular canons.
Synod of Hippo The synod of 393 is best known for two distinct acts. First, for the first time a council of bishops listed and approved a Christian Biblical canon that corresponds to the modern Roman Catholic canon while falling short of the Orthodox canon (including the books classed by Roman Catholics as deuterocanonical books and by Protestants as Apocrypha). The canon was later approved at the Council of Carthage (397) pending ratification by the "Church across the sea", that is, the See of Rome.[1] Previous councils had approved similar, but slightly different, canons. The council also reaffirmed the apostolic origin of the requirement of clerical continence and reasserted it as a requirement for all the ordained, in addition requiring that all members of a person's household must be Christian before that person can be ordained.[2][3]
