Alexander then called a synod of the church of Alexandria and its neighboring province of Mareotis in 320, for the specific intention of deciding what action would be taken regarding this increasingly problematic matter. At the synod, thirty-six presbyters and forty-four deacons, including Athanasius of Alexandria, agreed to a condemnation of Arianism and signed a document to that effect. Arius remained successful in spreading his new belief elsewhere, particularly in Mareotis and Libya, where Arius convinced the bishop Secundus of Ptolemais and Thomas of Marmarica to join him. Arius' success in dividing the leaders of the church made the chance of a formal schism a very real one.
