Saint Athanasius 
St. Athanasius on the Incarnation [PDF ebook] 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It aims primarily at helping the theological student who is working at the Greek text; but it may also prove welcome, it is hoped, to those who wish to read the work without having recourse to the Greek.
