This canon possesses a great interest and value to the student from a different point of view. Its provisions, both doctrinal and disciplinary, are in contrariety with the provisions of the council held at Carthage in the time of St. Cyprian, and yet both these canons, contradictory as they are, are accepted by the Council in Trullo and are given such ecumenical authority as canons on discipline ever can possess, by the Seventh Ecumenical. This is not the only matter in which the various conciliar actions adopted and ratified do not agree inter se, and from this consideration it would seem evident that it was not intended that to each particular of each canon of each local synod adopted, the express sanction of the Universal Church was given, but that they were received in block as legislation well calculated for the good of the Church. And that this must have been the understanding at the time is evinced by the fact that while the Trullan canons condemned a number of Western customs and usages, as I shall have occasion to point out in its proper place, no objection was made by the Roman legates to the canon of the Seventh Ecumenical which received them as authoritative.
