SAINT ATHANASIUS (c. 296-373), the Alexandrian patristic of the fourth century AD, was an astute apologist, proficient theologian, and champion of orthodox Christology. He earned the title Athanasius Contra Mundum for his willingness to take on the world in defending biblical truth. One of his most influential works, On the Incarnation, was written as an apologetic for the doctrine of the eternal Son of God taking to himself, without ceasing to be God, full humanity for the purpose of the Father's glory and our salvation. This classic has since inspired generations towards defending biblical truth.
