Ordinary (church officer)  An ordinary (from Latin "ordinarius") is an officer of a church or civic authority who by reason of office has ordinary power to execute laws. Such officers are found in hierarchically organised churches of Western Christianity which have an ecclesiastical legal system. For example, diocesan bishops are ordinaries in the Roman Catholic Church and the Church of England. In Eastern Christianity, a corresponding officer is called a hierarch (from Greek "hierarkhēs" "president of sacred rites, high-priest" which comes in turn from τὰ ἱερά "ta hiera", "the sacred rites" and ἄρχω "arkhō", "I rule"). In canon law, the power to govern the church is divided into the power to make laws (legislative), enforce the laws (executive), and to judge based on the law (judicial). An official exercises power to govern either because he holds an office to which the law grants governing power or because someone with governing power has delegated it to him. Ordinary power is the former, while the latter is delegated power. The office with ordinary power could possess the governing power itself (proper ordinary power) or instead it could have the ordinary power of agency, the inherent power to exercise someone else's power (vicarious ordinary power). The law vesting ordinary power could either be ecclesiastical law, i.e. the positive enactments that the church has established for itself, or divine law, i.e. the laws which the church believes were given to it by God. As an example of divinely instituted ordinaries, Catholics believe that when Jesus established the Church, he also established the episcopate and the primacy of Peter, endowing the offices with power to govern the Church. Thus, in the Catholic Church, the office of successor of Simon Peter and the office of diocesan bishop possess their ordinary power even in the absence of positive enactments from the Church. Many officers possess ordinary power but, due to their lack of ordinary executive power, are not called ordinaries. The best example of this phenomenon is the office of judicial vicar, a.k.a. "officialis". The judicial vicar only has authority through his office to exercise the diocesan bishop's power to judge cases. Though the vicar has vicarious ordinary judicial power, he is not an ordinary because he lacks ordinary executive power. A vicar general, however, has authority through his office to exercise the diocesan bishop's executive power.
