[Sidenote: 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 Homoean bishops retained their sees, but their influence was fast declining. The Anomoeans were forming a schism on one side, the Nicenes recovering power on the other. Unwilling signatures to the Homoean 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 Anomoeans 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.
