 The diaconate evolved as the liturgical assistants of the bishop and his delegate for the administration of Church funds and programmes for the poor.Today, the rank of "presbyter" is typically what one thinks of as a priest, although Church catechism considers both a bishop and a presbyter as "priests".Various churches which split off from the Catholic Church make the same claim of apostolic succession, including the Church of the East (split in 424), the Oriental Orthodoxy (split in 451) and the Eastern Orthodox Church (split with the East–West Schism of 1054).
