I have quoted already his letters on eastern affairs. They might be enlarged upon to any extent. As to those who held the highest rank, he has warm sympathy with a deposed patriarch of Antioch, sending him a copy of the letter which announced his accession, as well as to the sitting patriarchs. After twenty years' deposition Anastasius was restored. He has also close friendship with Eulogius, patriarch of Alexandria, to whom he writes gracefully: "Besides our mutual affection, there is a peculiar bond uniting us to the Alexandrian Church. All know that the Evangelist Mark was sent by his master Peter; thus we are clasped together by the unity of the master and the disciple. I seem to sit in the disciple's see for the master's sake, and you in the master's see for the sake of the disciple. To this we must add your personal merits; for we know how you follow the institutions of him from whom you spring. Thus we are touched with compassion for what you suffer; but we shrink from telling you what we endure ourselves by the daily plundering, killing, and maiming of our people by the Lombards."[199] Let us here take a short view of Gregory's incessant activity among the western nations in process of formation. In his struggle to tame the ferocity, lawlessness, and unbelief of the Lombards, he betakes himself to the illustrious Catholic queen Theodelinda. He strives to use her influence with her husband Agilulf, on behalf of Rome, ever the object of oppression. Knowing her to be a good Christian, he sent her his _Dialogues_. He also set before her the supremacy of his see, because she had been misled into withdrawing from the communion of the new archbishop of Milan, Constantius. The Pope assures her that the archbishop, as well as himself, venerates the doctrinal decisions of the Four Councils. He adds: "Since, then, by my own public profession you know the entireness of our belief, it is fitting that you have no further scruple concerning the Church of St. Peter, prince of the Apostles. But persist in the true faith, and ground your life on the rock of the Church, that is, in his confession: lest your many tears and your good works avail nothing, if they be separated from the true faith. For as branches wither without a root, so works, however good they seem, are nothing if separated from the solidity of the faith."[200]
