POLITY, ECCLESIASTICAL. By this is meant the constitution and government of the Christian Church, considered as a society.

Scarce anything in religion (says a learned author) has been more mistaken than the nature and extent of that power, which our blessed Saviour established in his Church. Some have not only excluded the civil magistrates of Christian states from having any concernment in the exercise of this power, and exempted all persons invested with it from the civil courts of justice, but have raised their supreme governor of the Church to a supremacy, even in civil affairs, over the chief magistrate; insomuch that he has pretended, on some occasions, to absolve subjects from their allegiance to their lawful princes; and others have run so far into contrary mistakes, as either to derive all spiritual power wholly from the civil magistrate, or to allow the exercise thereof to all Christians without distinction. The first of these opinions manifestly tends to create divisions in the State, and to excite subjects to rebel against their civil governors: the latter do plainly strike at the foundation of all ecclesiastical power; and wherever they are put in practice, not only the external order and discipline, but even the sacraments of the Church must be destroyed, and its whole constitution be quite dissolved.

The nature of ecclesiastical polity will be best understood by looking back to the constitution of the ancient Christian Church.

The Church, as a society, consisted of several orders of men. Eusebius reckons three: viz. the Ἡγούμενοι, Πιστοὶ, and Κατηχούμενοι, i. e. rulers, believers, and catechumens. Origen reckons five orders: but then he divides the clergy into three orders, to make up the number. Both these accounts, when compared together, come to the same thing. Under the Ἡγούμενοι, or rulers, are comprehended the clergy, bishops, priests, and deacons; under the Πιστοὶ, or believers, the baptized laity; and under the Κατηχούμενοι, or catechumens, the candidates for baptism. The believers were perfect Christians; the catechumens imperfect. The former, having received baptism, were allowed to partake of the eucharist; to join in all the prayers of the Church; and to hear discourses upon the most profound mysteries of religion: more particularly the use of the Lord’s Prayer was the sole prerogative of the believers, whence it was called Εὐχὴ πιστῶν, the prayer of believers. From all these privileges the catechumens were excluded. (See Catechumens.)

The distinction between the laity and the clergy may be deduced from the very beginnings of the Christian Church; notwithstanding that Rigaltius, Salmasius, and Selden pretend there was originally no distinction, but that it is a novelty, and owing to the ambition of the clergy of the third century, in which Cyprian and Tertullian lived. (See Clergy.)

The clergy of the Christian Church consisted of several orders, both superior and inferior.

The superior orders of the clergy were, 1. The Bishops; 2. The Presbyters; 3. The Deacons.

It has been pretended that the bishops and presbyters were the same; and this opinion has given rise to the sect of the Presbyterians. But it is clearly proved against them, from ecclesiastical antiquity, that bishops and presbyters were distinct orders of the clergy. (See Bishops, Deacons, Presbyters, and Presbyterians.)

Among the bishops there was a subordination, they being distinguished into, 1. Primate Metropolitans; 2. Patriarchs or Archbishops; 3. Diocesan Bishops; 4. Chorepiscopi or Suffragan Bishops. (See the articles Archbishops, Chorepiscopi, Diocese, Patriarchs. and Primates.)

The presbyters were the second order of the superior clergy, and besides being the bishop’s assistants in his cathedral church, had the care of the smaller districts, or parishes, of which each diocese consisted. (See Parishes and Presbyters.)
