Imperial and Ecclesiastical Acts in Consequence of the Decision of the Council of Sardica
Such were their letters, and such the sentence and the judgment of the Bishops in my behalf. But in order to prove that they did not act thus to ingratiate themselves, or under compulsion in any quarter, I desire, with your permission, to recount the whole matter from the beginning, so that you may perceive that the bishops wrote as they did with upright and just intentions, and that Ursacius and Valens, though they were slow to do so, at last confessed the truth.
