25 How carefully has Stephen fulfilled these salutary commands and warnings of the apostle, keeping in the first place lowliness of mind and meekness! For what is more lowly or meek than to have disagreed with so many bishops throughout the whole world, breaking peace with each one of them in various kinds of discord: at one time with the eastern churches, as we are sure you know; at another time with yon who are in the south, from whom he received bishops as messengers sufficiently patiently and meekly not to receive them even to the speech of an ordinary conference; and even more, so mindful of love and charity as to command the entire fraternity, that no one should receive them into his house, so that not only peace and communion, but also a shelter and entertainment, were denied to them when they came!
This is to have kept the unity of the Spirit in the bond of peace, to cut himself off from the unity of love, and to make himself a stranger in all respects from his brethren, and to rebel against the sacrament and the faith with the madness of contumacious discord! With such a man can there be one Spirit and one body, in whom perchance there is not even one mind, so slippery, and shifting, and uncertain is it?
