St. Alexander of Alexandria (died April 17, 326) was Patriarch of Alexandria from 313 to his death. During his priesthood he passed through the bloody persecutions of Galerius, Maximinus, and others. As bishop, Alexander is most notable for his conflict with Arius, who had begun to teach what came to be known as Arianism, that the Son had been created by God the Father at the beginning of time, under Alexander's predecessor Achillas.
