III. Timothy's request for indulgence on the score of orthodoxy must not be allowed.
Nor need we now state all that makes Timothy accursed, since what has been done through him and on his account, has abundantly and conspicuously come to the knowledge of the whole world, and whatever has been perpetrated by an unruly mob against justice, all rests on his head, whose wishes were served by its mad hands. And hence, even if in his profession of faith he neglects nothing, and deceives us in nothing, it best consorts with your glory absolutely to exclude him from this design of his, because in the bishop of so great a city the universal Church ought to rejoice with holy exultation, so that the true peace of the Lord may be glorified not only by the preaching of the Faith, but also by the example of men's conduct. Dated 17th of June, in the consulship of Magnus and Apollonius (460). (By the hand of Philoxenus agens in rebus.)
