With regard to the other Western Churches limits of space prevent any detailed account of Gregory’s dealings, but the following quotation, all the more valuable as coming from a Protestant authority, indicates very clearly the line he followed herein: “In his dealings with the Churches of the West, Gregory acted invariably on the assumption that all were subject to the jurisdiction of the Roman See. Of the rights claimed or exercised by his predecessors he would not abate one tittle; on the contrary, he did everything in his power to maintain, strengthen, and extend what he regarded as the just prerogatives of the papacy. It is true that he respected the privileges of the Western metropolitans, and disapproved of unnecessary interference within the sphere of their jurisdiction canonically exercised. . . . But of his general principle there can be no doubt whatever” (Dudden, I, 475). In view of later developments Gregory’s dealings with the Oriental Churches, and with Constantinople in particular, have a special importance. There cannot be the smallest doubt that Gregory claimed for the Apostolic See, and for himself as pope, a primacy not of honor, but of supreme authority over the Church Universal. In Epp., XIII, l, he speaks of “the Apostolic See, which is the head of all Churches”, and in Epp., V, cliv, he says: “I, albeit unworthy, have been set up in command of the Church.” As successor of St. Peter, the pope had received from God a primacy over all Churches (Epp., II, xlvi; III, xxx; V, xxxvii; VII, xxxvii). His approval it was which gave force to the decrees of councils or synods (Epp., IX, clvi), and his authority could annul them (Epp., V, xxxix, xli, xliv). To him appeals might be made even against other patriarchs, and by him bishops were judged and corrected if need were (Epp., II, l; III, lii, lxiii; IX, xxvi, xxvii). This position naturally made it impossible for him to permit the use of the title Ecumenical Bishop assumed by the Patriarch of Constantinople, John the Faster, at a synod held in 588. Gregory protested, and a long controversy followed, the question still at issue when the pope died. A discussion of this controversy is needless here, but it is important as showing how completely Gregory regarded the Eastern patriarchs as being subject to himself; “As regards the Church of Constantinople,” he writes in Epp., IX, xxvi, “who can doubt that it is subject to the Apostolic See? Why, both our most religious lord the emperor, and our brother the Bishop of Constantinople continually acknowledge it.” At the same time the pope was most careful not to interfere with the canonical rights of the other patriarchs and bishops. With the other Oriental patriarchs his relations were most cordial, as appears from his letters to the patriarchs of Antioch and Alexandria.
