subject to it, is indeed deified and exalted, but not removed or extinguished. Neither of the Two Natures can be without operation or without will. The Council thanked the emperor in a special address for his labours to bring about the peace of the Church, requested that five accredited copies of the decree of faith should be provided for the five patriarchal sees, and in a special letter to the Pope besought the confirmation of their decrees by him.(122) Besides this very brief summary of the eighteen sessions of the Sixth Council, it is requisite to take notice of certain documents which were either presented to the Council by the legates, as their commission from the Pope, or proceeded from the Council or the emperor at its conclusion. Pope Agatho had committed to his legates a long letter to the emperor. One passage from it may shew how plainly he set forth the authority of the Apostolic See and its inerrancy in matters of faith. He lays down the doctrine which opposes the Monothelite heresy, not as a matter for discussion, but as absolutely determined. “St. Peter,” he says, “received the charge to feed the spiritual sheep of the Church by a triple commendation from the Redeemer of all Himself. By his help this apostolical Church of his never turned aside from the way of truth to any error. The whole Catholic Church and General Councils followed in all things his authority as that of the chief of the apostles. This is the true rule of faith, which in prosperity and adversity the spiritual mother of your empire, the Apostolic Church of Christ, has kept unswervingly, which, by the grace of Almighty God, will be proved never to have erred from the path of apostolic tradition. It has never yielded to the corruption of heretical novelties, but as from the beginning of the Christian faith it has received from its authors the chief apostles, it has continued spotless according to the divine promise of the Lord our Saviour Himself, which He spoke to the chief of His disciples in the gospel: ‘Peter, behold Satan has sought to sift you, but I have prayed for thee,’ etc. Let your clemency consider how the Lord and Saviour of all, whose the faith is, who promised that the faith of Peter should not fail, charged him to confirm his brethren, which it is known to all that the apostolic pontiffs, my predecessors, have ever confidently done.”
