On the Incarnation of the Word is a classic work of Orthodox theology written by noted bishop of Alexandria, St. Athanasius. In this apologetic treatise, St. Athanasius defends the incarnation of Christ against the derision of 4th century non-believers. St. Athanasius explains why God chose to approach his fallen people in human form. He resolves the paradox of the Incarnate by relying heavily on both Scripture and the teachings of the early Church. St. Athanasius also answers several objections to his account, many of which are still raised against Christians today by those outside the Church. Though St. Athanasius wrote this text in the 4th century, his style is easy to follow and his concepts are of irreplaceable worth.

A universally acknowledged masterpiece of fourth-century patristic theology. As C. S. Lewis observes in his introduction: "When I first opened De Incarnatione I soon discovered by a very simple test that I was reading a masterpiece, for only a master mind could have written so deeply on such a subject with such classical simplicity."
