[The beginning of this epistle is the same as that of Epistle VII. to the same Anastasius as far as the words “stand on the shore of virtue”; after which it is continued as follows.]
But, as to your calling me the mouth and lantern of the Lord, and alleging that I profit many by speaking, and am able to give light to many, I confess that you have brought me into a state of the greatest doubt in my estimate of myself. For I consider what I am, and detect in myself no sign of all this good. But I consider also what you are, and I do not think that you can lie. When, then, I would believe what you say, my infirmity contradicts me. When I would dispute what is said in my praise, your sanctity contradicts me. But I pray you, holy man, let us come to some agreement in this our contest, that, though it is not as you say, it may be so because you say it. Moreover, I have addressed my synodical epistle to you, as to the other patriarchs, your brethren; inasmuch as with me you are always what it has been granted you to be by the gift of Almighty God, without regard to what you are accounted not to be by the will of men. I have given some instructions to Boniface the guardian (defensori), who is the bearer of these presents, for him to communicate to your holiness in private. Moreover, I have sent you keys of the blessed apostle Peter, who loves you, which are wont to shine forth with many miracles when placed on the bodies of sick persons.
