"My own desire is, for the common good of the world..."

My own desire is, for the common good of the world and the advantage of all mankind, that Thy people should enjoy a life of peace and undisturbed concord. Let those, therefore, who still delight in error, be made welcome to the same degree of peace and tranquility which they have who believe. For it may be that this restoration of equal privileges to all will prevail to lead them into the straight path. Let no one molest another, but let everyone believe as his soul desires. Only let men of sound judgment be assured of this, that those only can live a life of holiness and purity, whom Thou callest to a reliance on Thy holy laws. With regard to those who will hold themselves aloof from us, let them have, if they please, their temples of falsehood: we have the glorious edifice of Thy truth. We pray, however, that they too may receive the same blessing which Thou hast given in accordance with Thy Nature, and thus experience that heartfelt joy which unity of sentiment inspires.

- St. Constantine the Great, from Life of Constantine, by Eusebius, Book II, 56.
