Orthodox Apologetics

Creed and Catchword

The origin of these "confessional acclamations" of Christ ("God from God, Light from Light" etc.) was Alexander's party, but since it had become clear in years of wrangling that even their opponents could accept Christ's title as "god from God" (as meaning a nominal, inferior deity from the superior, absolute deity), many of the Alexandrians demanded a firmer test of faith. It was possibly Ossius [see Saints and Heretics], the theological adviser of the emperor, who suggested that the magic word to nail the Arian party would be homoousios. 

The term meant "of the same substance as," and when applied to the Logos it proclaimed that the Logos was divine in the same way as God the Father was divine (not in an inferior, different, or nominal sense). In short, if the Logos was homoousios with the Father, he was truly God alongside the Father. The word pleased Constantine, who seems to have seen it as an ideal way to bring all the bishops back on board for a common vote. It was broad enough to suggest a vote for the traditional Christian belief that Christ was divine, it was vague enough to mean that Christ was of the "same stuff" as God (no further debate necessary), and it was bland enough to be a reasonable basis for a majority vote. It had everything going for it as far as the politically savvy Constantine was concerned, but for the die-hard Arian party, it was a word too far. They saw that it gave the Son equality with the Father without explaining how this relationship worked. (In fact, it would be another 60 years before anyone successfully articulated the doctrine of the Trinity) Therefore they attacked it for undermining the biblical sense of the Son's obedient mission. The intellectuals among the group (chiefly Eusebius of Nicomedia) also attacked it for its crassness—it attributed "substance" (or material stuff) to God, who was beyond all materiality. Moreover, the term was unsuitable because it was "not found in the Holy Scriptures," and indeed this did disturb many of the bishops present for the occasion.

The great majority of bishops still endorsed the idea, however, and so with Constantine pressing for a consensus vote the word entered into the creed they published. It was not that the bishops at Nicaea were themselves simply looking for a convenient consensus in the synod's vote. Many synods had been held before this extraordinarily large one at Nicaea, and ancient bishops predominantly worked on the premise that decisions of the Church's leadership required unanimity. Their task was to proclaim the ancient Christian faith against all attacks, and this was not something they felt they had to seek out or worry over—they simply had to state among themselves a common and clear heritage, one that could be proclaimed by universal acclamation. They believed that they were the direct continuance of the first apostolic gathering at Jerusalem, when the Holy Spirit led all the apostles to the realization of the gospel truth. Because of this, when a few bishops dissented and refused their vote, the remaining bishops excommunicated and deposed them, accusing them of having refused to be part of the family of faith. Among this group was Eusebius of Nicomedia. All of the deposed bishops received harsh sentences from the emperor (although Eusebius was confident he could wiggle out of his disgrace, as soon he did).
