St. Athanasius passionately defended Christ’s deity during a time when Christological heresies were rampant, but what else did he contribute to Christianity? Here’s your crash course on the life and accomplishments of St. Athanasius—and why he still matters today.
Who Was St. Athanasius?
St. Athanasius (c. 296–373) was born and educated in the ancient city of Alexandria. Coming from a Christian family, he would go on to become the greatest theologian of his time. He assisted at the famous Council of Nicea in 325 when the historic Christian church condemned the influential heresy known as Arianism (the view that Jesus was the first and highest creature of God but not fully equal to God—this view is similar to the one advocated by present-day Jehovah’s Witnesses). St. Athanasius later became bishop of Alexandria, a post he held for 46 years, though he was exiled five times for his outspoken opposition to the vexing Arian heresy that continued to gain influence. St. Athanasius was an articulate, tenacious, and untiring defender of Nicene orthodoxy. He argued for the truth of such essential doctrines as the Incarnation and the Trinity.
