Chapter II.—The Emperor Gratian recalls the Orthodox Bishops, and expels the Heretics from the Churches. He takes Theodosius as his Colleague in the Empire.
Gratian being now in possession of the empire, together with Valentinian the younger, and condemning the cruel policy of his uncle Valens towards the [orthodox] Christians, recalled those whom he had sent into exile. He moreover enacted that persons of all sects, without distinction, might securely assemble together in their p. 119 churches; and that only the Eunomians, 682 Photinians, 683 and Manichæans 684 should be excluded from the churches. Being also sensible of the languishing condition of the Roman empire, and of the growing power of the barbarians and perceiving that the state was in need of a brave and prudent man, he took Theodosius as his colleague in the sovereign power. This [Theodosius] was descended from a noble family in Spain, and had acquired so distinguished a celebrity for his prowess in the wars, that he was universally considered worthy of imperial dignity, even before Gratians election of him. Having therefore proclaimed him emperor at Sirmium a city of Illyricum in the consulate 685 of Ausonius and Olybrius, on the 16th of January, he divided with him the care of managing the war against the barbarians.
