The conflict between the two began in earnest when Alexander declared the unity of the Trinity in one of his sermons. Arius immediately responded by labeling Alexander's statement Sabellianism, which had already been rejected by that time. The controversy quickly escalated, and Arius developed ever increasing support for his position, winning over a number of deacons, and at least one presbyter, who started to ordain presbyters of his own. Arius continued to draw even more attention and support, to the point that Alexander found himself having to summon two separate assemblies of his priests and deacons to discuss the matter. Neither of these assemblies, though, reached any firm conclusions, or helped to limit the spread of Arius' beliefs.
