Re-post from 2008.
Nikolaos (the one in the middle of the cluster to the right of Konstantinos) sat in the yellow sandstone cell. While his monastic lifestyle had accustomed him to harsh living conditions, he had normally sought them of his own will; being in prison was not the same as being a monk. He breathed in and out, trying to focus his thoughts, praying the name “Jesus” with each movement of his lungs.
“Jesus,” he breathed slowly in, focussing on the wall across from him. “Jesus,” he breathed out again. He had heard of some contemplatives who had made the prayer longer, larger, fuller, a declaration: “Lord Jesus Christ, Son of God, have mercy on me, a sinner.” Nikolaos had found that simply calling out the Name of the Anointed Jesus was all he needed, that by so doing the risen, ascended Lord of Creation came near to him and indwelt his being, making him full. It helped quiet his thoughts and bring him to a place where the praise of God could truly be always on his lips. “Jesus,” he uttered once more.
But now — now his thoughts were having trouble calming down. He had been shocked to hear of the declarations of Elder Arios of Alexandreia, who declared, “There was when he was not.” How could that be true? The Anointed Jesus is Lord, so all the Assembly of God, so all the New Jerusalem scattered across the world declared. And there is only one Lord, and he is God himself. For Nikolaos, it was simple — Jesus the Anointed was God enfleshed; he was the . . . the God-Man! God had taken flesh up into himself; by this action, all humanity was able to be redeemed. If the Anointed Jesus were not God, then we are not saved. Nikolaos would be doomed; so also would be Arios. As the letters, messengers, and travellers passed through Myra, Nikolaos, as overseer, had learned of Arios and of the condemnation of his teachings in Antiokheia.
When the summons to Nikaia came, Nikolaos could not stay away from Bithynia. He set out to this gathering of all the overseers of the world. He was, as anyone would be, impressed by the grandeur of Konstantinos, his palace, and the houses he had built for the Lord in the city. But, as a monk, he saw that no matter how much gold was poured out, no matter how many gems were embroidered in garments, no matter how many beautiful images were painted, the hearts of men are still corrupted and corruptible. Indeed, amidst the 300 overseers, he was surprised that there was less virtue and discipline than he had anticipated — almost as though the brief years of what some called the Triumph had already corroded the very fabric of the Assembly.
The meetings troubled Nikolaos still further. Arios was not the only one who held that the Anointed was a created being, that the Word was begotten and created! This was heresy; Jesus was begotten, not made. Arios’ supporters explained that at the base of everything in the universe lay one uncreated, unbegotten Being who had no beginning and who was free from the vicissitudes of change. This Being had one substance and one divine nature. This Being was the Being to whom the Anointed Jesus referred as Father. There could be but one divine nature, they argued, since there could be a single divine substance; if Jesus has a divine nature as well, he must share it with the Father. Either this produces two gods or it reproduces the teachings of Sabellios, which confuse the persons of the Son and the Father. Surely, they argued, none of the overseers present was a heretical Sabellian, or so uncultured as to say that somehow there could be two divine natures and somehow a single substance! This would go against the clearly demonstrable rules of philosophy!
“We are not here,” declared Nikolaos when they had continued on long enough about Platon and Aristoteles, “to discuss philosophy. Philosophy is created by man, by pagans; it is flawed. What has Athenai to do with Jerusalem? We are here to discuss the infallible truths of the Book and the Traditions of the Holy Ones! What do these tell us? Did not Holy Johannes, companion of our Lord, write, ‘In the beginning was the Word, and the Word was with God, and the Word was God’? How could the Word both be God and not God at once? Does not your Aristoteles warn against contradiction in his teachings on philosophy?”
An Arian had stood and said, “According to the Book of Proverbs, the Son of God was created before time and everything was created through him in his guise as the Wisdom of God; he is pre-eminent before the rest of creation; he goes by the names God, Word, Wisdom, and Strength due to the grace of God, not due to his very nature.” 
Nikolaos interrupted, “But does Holy Paulos not write in his letter to Philippi that he was in very nature God?”
“Yes,” came the Arian response, “but Holy Paulos continues and declares that the Anointed did not consider equality with God something to be grasped. But the Anointed had his will perfect with the Father for all time, despite his changeability; thus, the Father granted him glory before all worlds. He is subordinate in terms of rank, authority, and glory. The Son is alien and dissimilar in every way to the essence and selfhood of the Father. He is a creature.”
“I am a creature; you are a creature; this very building we overseers stand is a creature.”
“And so is the Anointed.”
“A creature? Like me? How in Hades could a creature save a fallen creature?! This is sheer self-contradictory madness!” Nikolaos turned his blazing monastic eyes to Arios amidst the elders and holy servants. As he did so, he stepped from among the overseers and mindlessly walked across the gathered council. “I had no idea your idiocy ran so deep, Arios! If you are not excommunicated by the end of this for your deep blasphemy and hatred of the truth, I shall turn in my holy orders as overseer in the Anointed’s Holy Assembly! For there is nothing holy about an assembly in which such destructive evils as your teachings can abide! You are a scoundrel and an anti-Christ, heretic!”
And then the peace-loving ascetic overseer from Myra, a man who believed only in doing good works for the Anointed and his people, did the unthinkable. Using his right hand, the old man struck Arios with a back-handed blow. Elder Arios stumbled backwards, Nikolaos’ ring of office leaving a mark on his face.
Thus Nikolaos found himself in turmoil in his cell, trying his utmost to pray the Jesus Prayer, seeking the place of rest, of inner peace, where he could abide with his Maker and calm his thoughts. As the cell grew dark, he lay down on the straw pallet and drifted into sleep in a strange city, suffering the harsh justice of the Revered Konstantinos.
