Canon XVII.
Since clerics of different churches have left their own churches in which they were ordained and betaken themselves to other bishops, and without the consent of their own bishop have been settled in other churches, and thus they have proved themselves to be insolent and disobedient; we decree that from the month of January of the past IV^th Indiction no cleric, of whatsoever grade he be, shall have power, without letters dimissory of his own bishop, to be registered in the clergy list of another church. Whoever in future shall not have observed this rule, but shall have brought disgrace upon himself as well as on the bishop who ordained him, let him be deposed together with him who also received him.
Notes.
Ancient Epitome of Canon XVII.
Whoever receives and ordains a wandering cleric shall be deposed together with him thus wickedly ordained.
This canon is found in the Corpus Juris Canonici, Gratian's Decretum, Pars II., Causa XXI., Quæst., ii. can. j.
Canon XVIII.
Those clerics who in consequence of a barbaric incursion or on account of any other circumstance have gone abroad, we order to return again to their churches after the cause has passed away, or when the incursion of the barbarians is at an end. Nor are they to leave them for long without cause. If anyone shall not have returned according to the direction of this present canon--let him be cut off until he shall return to his own church. And the same shall be the punishment of the bishop who received him.
Notes.
Ancient Epitome of Canon XVIII.
Whoever has emigrated on account of an invasion of the barbarians, shall return to the Church to whose clergy he belongs as soon as the incursion ceases. But if he shall not do so, he shall be cut off together with him to whom he has gone.

The Fathers are worthy of great praise. For having regard to the honour of the ecclesiastical order and of each bishop, they have decreed that clergymen, who from just and valid causes have gone forth without letters dimissory from those who ordained them, should return to their own clergy soon as the cause which drove them forth ceases; and that they should not be enrolled on the clergy list of any other church. But whosoever cannot be persuaded to return is to be cut off, as well as the bishop who detains him. But someone will say, If a bishop who does such a thing is cut off by his Metropolitan; and likewise if a Metropolitan spurns this canon he is punished by the Patriarch. But if an autocephalous archbishop or a Patriarch other than the Patriarch of Constantinople (for he has a faculty for doing so) should be convicted of a breach of this Canon, by whom would he be cut off? I suppose by the Supreme Pontiff [364] (oiomai oun para tou meizonos archiereos).
[364] Can this mean the Pope?
Canon XIX.
It behoves those who preside over the churches, every day but especially on Lord's days, to teach all the clergy and people words of piety and of right religion, gathering out of holy Scripture meditations and determinations of the truth, and not going beyond the limits now fixed, nor varying from the tradition of the God-bearing fathers. And if any controversy in regard to Scripture shall have been raised, let them not interpret it otherwise than as the lights and doctors of the church in their writings have expounded it, and in those let them glory rather than in composing things out of their own heads, lest through their lack of skill [365] they may have departed from what was fitting. For through the doctrine of the aforesaid fathers, the people coming to the knowledge of what is good and desirable, as well as what is useless and to be rejected, will remodel their life for the better, and not be led by ignorance, but applying their minds to the doctrine, they will take heed that no evil befall them and work out their salvation in fear of impending punishment.

The prelates of the Church, especially upon Lord's days, shall teach doctrine.

How great an obligation of preaching rests upon bishops, the successors of the Apostles, is evident from the words of St. Paul, "Christ sent me not to baptize but to preach" (1 Cor. i. 17), and his chief adjuration to Timothy though Jesus Christ and his coming, was "Preach the Word" (2 Tim. ii. 4.). For this reason the fathers formerly called the episcopate the preaching-office (officium predicationis), as is evident from the profession of Adelbert Morinensis, and the form of profession of a future Archbishop. Both of these will be found in Labbe, appendix to Tom. VIII., of his Concilia.
