This book consists of three lectures delivered by noted biblical scholar J. Armitage Robinson at Westminster Abbey on the theme of incarnation. Robinson chose to publish the lectures in response to a push by some quarters of the Anglican Communion to have the bishops declare the virgin birth a cardinal doctrine of the Christian faith. In an opening letter to the Archbishop of Canterbury, Robinson appeals that the door of inquiry not be closed by the hand of authority. In light of these concerns regarding the doctrine of the virgin birth, he sets to investigate four elements. First, what do we mean by the incarnation; secondly, what led up to the incarnation and made it possible; thirdly, how as a matter of historical fact it was realized on the stage of the world; and lastly, what are its chief lessons and most important issues.
