The Synod of Hippo refers to the synod of 393 A.D. which was hosted in Hippo Regius in northern Africa during the early christian church. Additional synods were held in 394, 397, 401 and 426.
Some were attended by St. Augustine. The synod of 393 is most known for two distinct acts. First, for the first time a council of bishops listed and approved a canon of Sacred Scripture that corresponds to the modern Roman Catholic canon, including the deuterocanonical books classed by Protestants as "Apocrypha". The canon was later approved at the Council of Carthage pending the ratification of the "Church across the sea". Previous councils had approved of similar, but slightly different canons. Second, the council reaffirmed the apostolic origin of the requirement of clerical continence and reasserted it as a requirement for all the ordained.
