The Arians relied in their theology on several early versions of the Greek mass and other texts in which Jesus was described as "homoios" to the Father, meaning - resembling or being like the Father. The Council of Nicaea relied on the same texts, but in them the word "homoios" was replaced with the shorter "homos", meaning - identical, one and the same. Many of the theological debates between the two sects revolved around the question of the authenticity of these texts, trying to ascertain who had the earlier version.
