Attraction of Arianism: (1.) For superficial thinkers.
Yet there were many men whom Arianism suited by its shallowness. As soon as Christianity was established as a lawful worship by the edict of Milan in 312, the churches were crowded with converts and inquirers of all sorts. A church which claims to be universal cannot pick and choose like a petty sect, but must receive all comers. Now these were mostly heathens with the thinnest possible varnish of Christianity, and Arianism enabled them to use the language of Christians without giving up their heathen ways of thinking. In other words, the world was ready to accept the gospel as a sublime monotheism, and the Lord's divinity was the one great stumbling-block which seemed to hinder its conversion. Arianism was therefore a welcome explanation of the difficulty. Nor was the attraction only for nominal Christians like these. Careless thinkers—sometimes thinkers who were not careless—might easily suppose that Arianism had the best of such passages as 'The Lord created me,'[1] or 'The Father is greater than I.'[2] Athanasius constantly complains of the Arian habit of relying on isolated passages like these without regard to their context or to the general scope and drift of Scripture.

(2.) To thoughtful men.
Nor was even this all. The Lord's divinity was a real difficulty to thoughtful men. They were still endeavouring to reconcile the philosophical idea of God with the fact of the incarnation. In point of fact, the two things are incompatible, and one or the other would have to be abandoned. The absolute simplicity of the divine nature is consistent with a merely external Trinity, or with a merely economic Trinity, with an Arian Trinity of one increate and two created beings, or with a Sabellian Trinity of three temporal aspects of the one God revealed in history; but not with a Christian Trinity of three eternal aspects of the divine nature, facing inward on each other as well as outward on the world. But this was not yet fully understood. The problem was to explain the Lord's distinction from the Father without destroying the unity of God. Sabellianism did it at the cost of his premundane and real personality, and therefore by common consent was out of the question. The Easterns were more inclined to theories of subordination, to distinctions of the derivatively from the absolutely divine, and to views of Christ as a sort of secondary God. Such theories do not really meet the difficulty. A secondary God is necessarily a second God. Thus heathenism still held the key of the position, and constantly threatened to convict them of polytheism. They could not sit still, yet they could not advance without remodelling their central doctrine of the divine nature to agree with revelation. Nothing could be done till the Trinity was placed inside the divine nature. But this is just what they could not for a long time see. These men were not Arians, for they recoiled in genuine horror from the polytheistic tendencies of Arianism; but they had no logical defence against Arianism, and were willing to see if some modification of it would not give them a foothold of some kind. To men who dreaded the return of Sabellian confusion, Arianism was at least an error in the right direction. It upheld the same truth as they—the separate personality of the Son of God—and if it went further than they could follow, it might still do service against the common enemy.
Arianism at Alexandria.
Thus the new theory made a great sensation at Alexandria, and it was not without much hesitation and delay that Alexander ventured to excommunicate his heterodox presbyter with his chief followers, like Pistus, Carpones, and the deacon Euzoius—all of whom we shall meet again. Arius was a dangerous enemy. His austere life and novel doctrines, his dignified character and championship of 'common sense in religion,' made him the idol of the ladies and the common people. He had plenty of telling arguments for them. 'Did the Son of God exist before his generation?' Or to the women, 'Were you a mother before you had a child?' He knew also how to cultivate his popularity by pastoral visiting—his enemies called it canvassing—and by issuing a multitude of theological songs 'for sailors and millers and wayfarers,' as one of his admirers says. So he set the bishop at defiance, and more than held his ground against him. The excitement spread to every village in Egypt, and Christian divisions became a pleasant subject for the laughter of the heathen theatres.
And elsewhere.
The next step was to secure outside support. Arius betook himself to Cæsarea in Palestine, and thence appealed to the Eastern churches generally. Nor did he look for help in vain. His doctrine fell in with the prevailing dread of Sabellianism, his personal misfortunes excited interest, his dignified bearing commanded respect, and his connection with the school of Lucian secured him learned and influential sympathy. Great Syrian bishops like those of Cæsarea, Tyre, and Laodicea gave him more or less encouragement; and when the old Lucianist Eusebius of Nicomedia held a council in Bithynia to demand his recall, it became clear that the controversy was more than a local dispute. Arius even boasted that the Eastern bishops agreed with him, 'except a few heretical and ill-taught men,' like those of Antioch and Jerusalem.
