While Basil had risen, by Gregory's help, to be an archbishop, Gregory himself was still a presbyter. He would not have taken even this office but that his father ordained him to it almost by force; and he had a great dread of being raised to the high and difficult office of a bishop. But Basil, for certain reasons, wished to establish a bishop in a little town called Sasima, and he fixed on his old friend, without, perhaps, thinking so much as he ought to have thought, whether the place and the man were likely to suit each other. The old bishop of Nazianzum did all that he could to overcome his son's unwillingness, and Gregory was consecrated; but he thought himself unkindly used, and complained much of Basil's behaviour in the matter. After a time, Basil and other leaders of the orthodox (that is, of those who _held the right faith_) urged Gregory to undertake a mission to Constantinople, and he agreed to go, in the hope of being able to do some good (A.D. 378). The bishopric of that great city had been in the hands of Arians for nearly forty years, and although there were many people of other sects there, the orthodox were but a handful. Gregory, when he began his labours, found that there was a strong feeling against him and his doctrine. He could not get the use of any church, and was obliged to hold his service in a friend's house. He was often attacked by the Arian mob; he was stoned; he was carried before the magistrates on charges of disturbing the peace; the house which he had turned into a chapel was broken into by night, and shocking outrages were committed in it. But the good Gregory held on notwithstanding all this, and, after a while, his mild and grave character, his eloquent and instructive preaching, and the piety of his life, wrought a great change, so that his little place of worship became far too small to hold the crowds which flocked to it. While Gregory was thus employed, Basil died, in the year 380. PART II. Both parts of the empire were now again under orthodox princes. Valens had lost his life in war, without leaving any children (A.D. 378), so that Valentinian's sons, Gratian and Valentinian the Second, were heirs to the whole. But Gratian felt the burden of government too much for himself, a lad of nineteen, and for his little brother, who was but seven years old; and he gave up the East to a brave Spaniard, named Theodosius, in the hope that he would be able to defend it. Theodosius came to Constantinople in the year 380, and found things in the state which has just been described. He turned the Arian bishop and his clergy out of the churches, and gave Gregory possession of the cathedral. Gregory knew that the emperor wished to help the cause of the true faith, and he did as Theodosius wished; but he was very sad and uneasy at being thus thrust on a flock of which the greater part as yet refused to own him.
