It was always believed in the Church that the power of binding and loosing had been entrusted by our Lord to His apostles, and by them handed on to their successors in the ministry. The earlier practice would seem to have been short and simple: exclusion from Communion, some outward discipline, not always continued for a long period, and reconciliation on true repentance, these matters being decided by the bishop at his discretion. Gradually the practice became more systematized, various periods of discipline were prescribed for various sins, and the time for this discipline was lengthened.
