This course offers an in-depth exploration of the life and work of St. Athanasius, one of the most influential defenders of Nicene orthodoxy. We will examine not only his role as a theologian and polemicist in the context of the Arian controversy but also his multifaceted identity as a pastor, spiritual leader, and promoter of the Egyptian desert monastic movement. Through a careful study of his writings and historical context, students will gain insight into Athanasius’s theological contributions, his pastoral concerns, and his enduring legacy in the shaping of Christian doctrine and practice.
