Ancient Epitome of Canon IX.
Bishops should be bound to the opinion of the metropolitan, and nothing should they do without his knowledge except only such things as have reference to the diocese of each, and let them ordain men free from blame.
From this canon we see that causes of more importance and greater moment are to be considered in the Provincial Synod which consisted of the metropolitan and the other bishops of the province.
By the "ancient canon" of which mention is here made, there can scarcely be a doubt is intended the xxxiv. of the Canons of the Apostles, since in it are read the same provisions (and almost in the same words) as here are set forth somewhat more at length; nor is there any other canon in which these provisions are found earlier in date than this synod, wherefore from this is deduced a strong argument for the integrity of the Canons of the Apostles.
The wording of this canon should be compared with the famous sentence so often quoted of St. Irenæus. "Ad hanc enim ecclesiam [i.e. of Rome] propter potentiorem principalitatem necesse est omnem convenire ecclesiam, hoc est, eos qui sunt undique fideles, in quâ semper ab his, qui sunt undique, conservata est eaque est ab Apostolis traditio."
Is it not likely that in the lost Greek original the words translated convenire ad were suntrechein en? Vide on the meaning of convenire ad, F. W. Puller, The Primitive Saints and the See of Rome, pp.32 et seqq.
