Epistle III.

To Constantius, Bishop.

Gregory to Constantius, Bishop of Mediolanum.

It has come to my knowledge that certain bishops of your diocese, seeking out rather than finding an occasion, have attempted to sever themselves from the unity of your Fraternity, saying that thou hadst given a security at the Roman city for thy condemnation of the three Chapters.&#160; And the fact is that they say this because they do not know how I am accustomed to trust thy Fraternity even without security.&#160; For if there had been need for anything of the kind, your mere word of mouth could have been trusted.&#160; I, however, do not recollect any mention between us of the three Chapters either in word or in writing.&#160; But as for them, if they soon return from their error, they should be spared, because, according to the saying of the Apostle Paul, They understand neither what they say nor whereof they affirm (1 Tim. i. 7).&#160; For we, truth guiding us and our conscience bearing witness, declare that we keep the faith of the holy synod of Chalcedon in all respects inviolate, and venture not to add anything to, or to subtract anything from, its definition .&#160; But, if any one would fain take upon himself to think anything, either more or less, contrary to it, and to the faith of this same synod, we anathematize him without any hesitation, and decree him to be alien from the bosom of Mother Church.&#160; Any one, therefore, whom this my confession does not bring to a right mind, no longer loves the synod of Chalcedon, but hates the bosom of Mother Church.&#160; If then those who appear to have been thus daring have presumed thus to speak in zeal of soul, it remains for them, having received this satisfaction, to return to the unity of thy Fraternity, and not divide themselves from the body of Christ, which is the holy universal Church.
