There are canon laws of ecumenical councils, of provincial and local councils, and of individual church fathers which have been received by the entire Orthodox Church as normative for Christian doctrine and practice. As a word canon means literally rule or norm or measure of judging. In this sense the canon laws are not positive laws in the juridical sense and cannot be easily identified with laws as understood and operative in human jurisprudence.
The canons of the Church are distinguished first between those of a dogmatic or doctrinal nature and those of a practical, ethical, or structural character. They are then further distinguished between those which may be changed and altered and those which are unchangeable and may not be altered under any conditions.
The dogmatic canons are those council definitions which speak about an article of the Christian faith; for example, the nature and person of Jesus Christ. Although such canons may be explained and developed in new and different words, particularly as the Church Tradition grows and moves through time, their essential meaning remains eternal and unchanging.
Some canons of a moral and ethical character also belong to those which cannot be changed. These are the moral canons whose meaning is absolute and eternal and whose violation can in no way be justified. The canons which forbid the sale of Church sacraments are of this kind.
There are, in addition, canons of a quite practical nature which may be changed and which, in fact, have been changed in the course of the life of the Church. There are also those which may be changed but which remain in force since the Church has shown the desire to retain them. An example of the former type is the canon which requires the priests of the church to be ordained to office only after reaching thirty years of age. It might be said that although this type of canon remains normative and does set a certain ideal which theoretically may still be of value, the needs of the Church have led to its violation in actual life. The canon which requires that the bishops of the Church be unmarried is of the latter type.
It is not always clear which canons express essential marks of Christian life and which do not. There are often periods of controversy over certain canons as to their applicability in given times and conditions. These factors, however, should not lead the members of the Church to dismay or to the temptation either to enforce all canons blindly with identical force and value or to dismiss all the canons as meaningless and insignificant.
In the first place, the canons are “of the Church” and therefore cannot possibly be understood as “positive laws” in a juridical sense; secondly, the canons are certainly not exhaustive, and do not cover every possible aspect of Church faith and life; thirdly, the canons were produced for the most part in response to some particular dogmatic or moral question or deviation in the Church life and so usually bear the marks of some particular controversy in history which has conditioned not merely their particular formulation, but indeed their very existence.
Taken by themselves, the canon laws of the Church can be misleading and frustrating, and therefore superficial people will say “either enforce them all or discard them completely.” But taken as a whole within the wholeness of Orthodox life—theological, historical, canonical, and spiritual —- these canons do assume their proper place and purpose and show themselves to be a rich source for discovering the living Truth of God in the Church. In viewing the canons of the Church, the key factors are Christian knowledge and wisdom which are borne from technical study and spiritual depth. There is no other “key” to their usage; and any other way would be according to the Orthodox faith both unorthodox and unchristian.
