‘And the Word became flesh and dwelt among us’ (John 1:14). Saint Athanasius of Alexandria (c.296–373) took this verse from the Gospel of John in order to unpack his Christology of the incarnation. In this essay I will examine the work of Athanasius in order to study the claim that ‘The Word became flesh.’ Athanasius argued that God ‘became man, and did not come into man.’ The implications of his conviction are firstly, only God could save humanity and secondly, the Word was fully divine. I will assess the implications of Athanasius’ arguments in his treatise ‘On the Incarnation’ with reference to some of his other works.
