ECCLESIASTICAL LAW, in its broadest sense, the sum of the authoritative rules governing the Christian Church, whether in its internal polity or in its relations with the secular power. Since there are various churches, widely differing both in their principles and practice, it follows that a like difference exists in their ecclesiastical law, which is the outcome of their corporate consciousness as modified by their several relations to the secu lar authority. At the outset a distinction must be made between churches which are "established" and those that are "free." The ecclesiastical laws of the latter are, like the rules of a private society or club, the concern of the members of the church only, and come under the purview of the State only in so far as they come in conflict with the secular law (e.g., polygamy among the Mormons, or violation of the trust-deeds under which the property of a church is held). In the case of "established" churches, on the other hand, whatever the principle on which the system is based, or the difference in its practical application, the essential conditions are that the ecclesiastical law is also the law of the land, the decisions of the church courts being enforced by the civil power. This holds good both of the Roman Catholic church, wherever this is recognized as the "State religion," of the Oriental churches, whether closely identified with the State itself, or en dowed with powers over particular nationalities within the State, and of the various Protestant churches established in Great Britain and on the Continent of Europe.
Writers on the theory of ecclesiastical law, moreover, draw a fundamental distinction between that of the church of Rome and that of the Protestant national or territorial churches. This distinction is due to the claim of the Roman Catholic church to be the only church, her laws being thus of universal obligation; whereas the laws of the various established Protestant churches are valid—at least so far as legal obligation is concerned—only within the limits of the countries in which they are established. The practical effects of this distinction have been, and still are, of enormous importance. The Roman Catholic church, even when recognized as the State religion, is nowhere "established" in the sense of being identified with the State, but is rather an imperium in imperio which negotiates on equal terms with the State, the results being embodied in concordats (q.v.) between the State and the pope as head of the church. The concordats are of the nature of truces in the perennial conflict between the spiritual and secular powers, and imply in principle no surrender of the claims of the one to those of the other.
Protestant ecclesiastical law, then, is distinguished from that of the Roman Catholic church (I) by being more limited in its scope, (2) by having for its authoritative source, not the church only or even mainly, but the church in more or less complete union with or subordination to the State, the latter being considered, equally with the church, as an organ of the will of God. The ecclesiastical law of the church of Rome, on the other hand, what ever its origin, is now valid only in so far as it has the sanction of the authority of the Holy See. And it must be noted that the "canon law" in its old sense is not identical with the "ecclesiastical law" of the Roman Catholic church. By the canon law used to be meant the contents of the Corpus iuris canonici, which have been largely superseded or added to by, e.g., the canons of the Council of Trent and the Vatican decrees. The long projected codification of the whole of the ecclesiastical law of the church of Rome, was completed in 1917 in the pontificate of Benedict XV. (See also CANON LAW and ECCLESIASTICAL JURISDICTION.) The ecclesiastical law of England is in complete dependence upon the authority of the State. The convocations of York and Canterbury are provincial assemblies possessing no legislative or judicial authority; even such purely ecclesiastical questions as may be formally commended to their attention by "letters of business" from the Crown can only be finally settled by act of parliament or, under the Church of England Assembly (Powers) Act 1919, by a measure passed by the church assembly and then assented to by a separate resolution in each house of parliament and submitted for royal assent. The ecclesiastical courts are for the most part officered by laymen, whose subordination to the archbishops and bishops is purely formal, and the final court of appeal is the Judicial Committee of the Privy Council. In like manner changes in the ecclesiastical law have been made directly by parliament in the ordinary course of legislation, and in point of fact a very large portion of the existing ecclesiastical law con sists of acts of parliament.
The first principle of the ecclesiastical law in England is the assertion of the supremacy of the Crown, which in the present state of the constitution means the same thing as the supremacy of parliament. This principle has been maintained ever since the Reformation. Before the Reformation the ecclesiastical suprem acy of the pope was recognized, with certain limitations, in Eng land, and the church itself had some pretensions to ecclesiastical freedom. The freedom of the church is, in fact, one of the standing provisions of those charters on which the English con stitution was based. The first provision of Magna Carta is quod ecclesia Anglicana libera sit. By the various enactments of the period of the Reformation the whole constitutional position of the church, not merely with reference to the pope but with refer ence to the State, was definitely fixed. The legislative power of convocation was held to extend to the clergy only, and even to that extent required the sanction and assent of the Crown. The common law courts controlled the jurisdiction of the ecclesiastical courts, claiming to have "the exposition of such statutes or acts of parliament as concern either the extent of the jurisdiction of these courts or the matters depending before them. And therefore if these courts either refuse to allow these acts of parliament, or expound them in any other sense than is truly and properly the exposition of them, the king's great courts of common law may prohibit and control them." The design of constructing a code of ecclesiastical laws was entertained during the period of the Reformation but never car ried into effect. It is alluded to in various statutes of tlie reign of Henry VIII., who obtained power to appoint a commission to examine the old ecclesiastical laws, with a view of deciding which ought to be kept and which ought to be abolished, and in the meantime it was enacted that "such canons, institutions, ordi nances, synodal or provincial, or other ecclesiastical laws or juris dictions spiritual as be yet accustomed and used here in the church of England, which necessarily and conveniently are requi site to be put in ure and execution for the time, not being repug nant, contrarient, or derogatory to the laws or statutes of the realm, nor to the prerogatives of the royal crown of the same, or any of them, shall be occupied, exercised, and put in ure for the time with this realm" (25 Henry VIII. c. 19, 35 c. 16).
The work was actually undertaken and finished in the reign of Edward VI. by a subcommittee of eight persons, under the name of the Re f ormatio legum ecclesiasticarum, which, however, never obtained the royal assent. Although the powers of the 25 Henry VIII. c. 19, were revived by the I Elizabeth c. 1, the scheme was never executed, and the ecclesiastical laws remained on the foot ing assigned to them in that statute—so much of the old ecclesias tical laws might be used as had been actually in use, and was not repugnant to the laws of the realm.
The statement is, indeed, made by Sir R. Phillimore (Ecclesias tical Law, end ed., 1895) that the "Church of England has at all times, before and since the Reformation, claimed the right of an independent church in an independent kingdom, to be governed by the laws which she has deemed it expedient to adopt." This position can only be accepted if it is confined, as the authorities cited for it are confined, to the resistance of interference from abroad. If it mean that the church, as distinguished from the kingdom, has claimed to be governed by laws of her own making, all that can be said is that the claim has been singularly unsuc cessful. From the time of the Reformation no change has been made in the law of the church which has not been made by the king and parliament, sometimes indirectly, as by confirming the resolutions of convocation, but for the most part by statute. The list of statutes cited in Sir R. Phillimore's Ecclesiastical Law fills II pages. It is only by a kind of legal fiction that the church can be said to have deemed it expedient to adopt these laws.
The terms on which the church establishment of Ireland was abolished, by the Irish Church Act of 1869, may be mentioned. By s. 20 the present ecclesiastical law was made binding on the members for the time being of the church, "as if they had mutu ally contracted and agreed to abide by and observe the same"; and by s. 21 it was enacted that the ecclesiastical courts should cease after Jan. 1, 1871, and that the ecclesiastical laws of Ireland, except so far as relates to matrimonial causes and matters, should cease to exist as law.
