Arius 

Unhappily, he went to the other extreme. If the Father was absolutely one, where did the Son come in? Arius explained it thus: “The Father existed before the Son. There was a Son come in? Arius explained it thus: “The Father existed before the Son. There was a time when the Son did not exist. Therefore, the Son was created by the Father. Therefore, although the Son was the highest of all creatures, he was not of the essence of God.”  Who's Who In Christian History - Tyndale House Publishers, Inc. - J. D. DOUGLAS

I think Arius was ignorant of the Bible, It seems he never read, “3. Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high:” If the Lord Jesus Christ is the brightness of the glory of God, and He is created then God was darkness. So Arius is speaking about the god of darkness and not the God of light the Lord Jesus Christ. 

 At the end of the council Arius was excommunicated, but within two years he deceived Constantine into thinking he was orthodox at heart. Athanasius, who became bishop of Alexandria in 328, would not have Arius back in the city, and this became a source of unrest, fully exploited by Athanasius’s enemies. Even when the exasperated Constantine sent Athanasius into exile, Arius was refused Communion in the diocese and returned to Constantinople, where he soon died.  Who's Who In Christian History - Tyndale House Publishers, Inc. - J.

In the verse below , “God was manifest in the flesh” KJV and  “he appeared in a body”. NIV   It is clear that the KJV starts a sentence with God, While the NIV starts with He. But we know that He is not the translation of  “oV”  The right translation is “who”  but the word who in the beginning  of a sentence makes the statement a question. This statement is not a question so they were forced to change it to He. Now the question who have changed the   “QeoV” to“oV”? Arius have said, “the Son was created by the Father.”. So Arius aim was in life to prove his point so he tampered with Greek Text and with the Septuagint to reach his aim.  So all the Greek text that reads “oV” are text that were effected by Arius, Pamphilus,  Eusebius or by one of the followers of Arius.
