Breach between church and state.
The contest entered on a new stage in the reign of Valens. The friendly league of church and state at Nicæa had become a struggle for supremacy. Constantius endeavoured to dictate the faith of Christendom according to the pleasure of his eunuchs, while Athanasius reigned in Egypt almost like a rival for the Empire. And if Julian's reign had sobered party spirit, it had also shown that an emperor could sit again in Satan's seat. Valens had an obedient Homœan clergy, but no trappings of official splendour could enable Eudoxius or Demophilus to rival the imposing personality of Athanasius or Basil. Thus the Empire lost the moral support it looked for, and the church became embittered with its wrongs.
Rise of monasticism.
The breach involved a deeper evil. The ancient world of heathenism was near its dissolution. Vice and war, and latterly taxation, had dried up the springs of prosperity, and even of population, till Rome was perishing for lack of men. Cities had dwindled into villages, and of villages the very names had often disappeared. The stout Italian yeomen had been replaced by gangs of slaves, and these again by thinly scattered barbarian serfs. And if Rome grew weaker every day, her power for oppression seemed only to increase. Her fiscal system filled the provinces with ruined men. The Alps, the Taurus, and the Balkan swarmed with outlaws. But in the East men looked for refuge to the desert, where many a legend told of a people of brethren dwelling together in unity and serving God in peace beyond the reach of the officials. This was the time when the ascetic spirit, which had long been hovering round the outskirts of Christianity, began to assume the form of monasticism. There were monks in Egypt—monks of Serapis—before Christianity existed, and there may have been Christian monks by the end of the third century. In any case, they make little show in history before the reign of Valens. Paul of Thebes, Hilarion of Gaza, and even the great Antony are only characters in the novels of the day. Now, however, there was in the East a real movement towards monasticism. All parties favoured it. The Semiarians were busy inside Mount Taurus; and though Acacians and Anomœans held more aloof, they could not escape an influence which even Julian felt. But the Nicene party was the home of the ascetics. In an age of indecision and frivolity like the Nicene, the most earnest striving after Christian purity will often degenerate into its ascetic caricature. Through the selfish cowardice of the monastic life we often see the loving sympathy of Christian self-denial. Thus there was an element of true Christian zeal in the enthusiasm of the Eastern Churches; and thus it was that the rising spirit of asceticism naturally attached itself to the Nicene faith as the strongest moral power in Christendom. It was a protest against the whole framework of society in that age, and therefore the alliance was cemented by a common enmity to the Arian Empire. It helped much to conquer Arianism, but it left a lasting evil in the lowering of the Christian standard. Henceforth the victory of faith was not to overcome the world, but to flee from it. Even heathen immorality was hardly more ruinous than the unclean ascetic spirit which defames God's holy ordinance as a form of sin which a too indulgent Lord will overlook.
New questions in controversy.
Valens was only a catechumen, and had no policy to declare for the present. Events therefore continued to develop naturally. The Homœan bishops retained their sees, but their influence was fast declining. The Anomœans were forming a schism on one side, the Nicenes recovering power on the other. Unwilling signatures to the Homœan creed were revoked in all directions. Some even of its authors declared for Arianism with Euzoius, while others drew nearer to the Nicene faith like Acacius. On all sides the simpler doctrines were driving out the compromises. It was time for the Semiarians to bestir themselves if they meant to remain a majority in the East. The Nicenes seemed daily to gain ground. Lucifer had compromised them in one direction, Apollinarius in another, and even Marcellus had never been frankly disavowed; yet the Nicene cause advanced. A new question, however, was beginning to come forward. Hitherto the dispute had been on the person of the Lord, while that of the Holy Spirit was quite in the background. Significant as is the tone of Scripture, the proof is not on the surface. The divinity of the Holy Spirit is shown by many convergent lines of evidence, but it was still an open question whether that divinity amounts to co-essential and co-equal deity. Thus Origen leans to some theory of subordination, while Hilary limits himself with the utmost caution to the words of Scripture. If neither of them lays down in so many words that the Holy Spirit is God, much less does either of them class him with the creatures, like Eunomius. The difficulty was the same as with the person of the Lord, that while the Scriptural data clearly pointed to his deity, its admission involved the dilemma of either Sabellian confusion or polytheistic separation. Now, however, it was beginning to be seen that the theory of hypostatic distinctions must either be extended to the Holy Spirit or entirely abandoned. Athanasius took one course, the Anomœans the other, but the Semiarians endeavoured to draw a distinction between the Lord's deity and that of the Holy Spirit. In truth, the two are logically connected. Athanasius pointed this out in the letters of his exile to Serapion, and the council of Alexandria condemned 'those who say that the Holy Spirit is a creature and distinct from the essence of the Son.' But logical connection is one thing, formal enforcement another. Athanasius and Basil to the last refused to make it a condition of communion. If any one saw the error of his Arian ways, it was enough for him to confess the Nicene creed. Thus the question remained open for the present.
Council of Lampsacus (364).
Thus the Semiarians were free to do what they could against the Homœans. Under the guidance of Eleusius of Cyzicus, they held a council at Lampsacus in the summer of 364. It sat two months, and reversed the acts of the Homœans at Constantinople four years before. Eudoxius was deposed (in name) and the Semiarian exiles restored to their sees. With regard to doctrine, they adopted the formula like according to essence, on the ground that while likeness was needed to exclude a Sabellian (they mean Nicene) confusion, its express extension to essence was needed against the Arians. Nor did they forget to re-issue the Lucianic creed for the acceptance of the churches. They also discussed without result the deity of the Holy Spirit. Eustathius of Sebastia for one was not prepared to commit himself either way. The decisions were then laid before Valens.
The Homœan policy of Valens.
But Valens was already falling into bad hands. Now that Julian was dead, the courtiers were fast recovering their influence, and Eudoxius had already secured the Emperor's support. The deputies of Lampsacus were ordered to hold communion with the bishop of Constantinople, and exiled on their refusal.
