The notion of apostolic succession (i.e., the ability of a bishop to trace spiritual ancestry through a purportedly unbroken line of bishops back to the original faith established by Jesus of Nazareth and his apostles) has played an important role in the history of the western Church since the Donatist controversy in the fourth and fifth centuries AD. The traditional Catholic position holds that a validly consecrated bishop shares apostolic succession with the bishops he consecrates and the priests and deacons he ordains regardless of any heresy or schism he may have committed. Some theologians argue that this view is mechanical and reductionist, and that episcopal consecration is for service within a specific Christian community; in this view, consecration or ordination of an individual with no reference to a community is without effect. Independent Catholic clergy reject this view, arguing that bishops are consecrated and priests and deacons ordained for the service of others, whether of a defined community or jurisdiction, or of a more broadly defined group. Independent Catholics tend to share the view that, "whatever else we may disagree about, we all believe earnestly in apostolic succession!"
