De Incarnatione Verbi Dei
This translation was made by Sister Penelope Lawson, of the Anglican Community of St. Mary the Virgin in Wantage, England. It was originally published with a byline that reads only "Translated and edited by A Religious of C.S.M.V."
With Introduction by C. S. Lewis
Athanasius stood contra mundum ("against the world") in defense of the biblical doctrine of Christ. He opposed Arius when it seemed all the world would follow Arius's heresy. Athanasius's work remains even today one of the definitive statements of orthodox Trinitarianism.
