Cur Deus Homo, also known as Why God Became Man, is a theological treatise written by Saint Anselm of Canterbury in the 11th century. The book is a dialogue between Anselm and his student, Boso, in which they discuss the nature of sin, justice, and the need for redemption. Anselm argues that sin is a violation of God's honor and justice, and that only a perfect being can make amends for it. Therefore, God became man in the form of Jesus Christ to offer himself as a sacrifice for the sins of humanity. Anselm's argument is based on the concept of satisfaction, which states that a debt can only be paid by the person who owes it. The book is considered a seminal work in the development of Christian theology and has influenced many subsequent theologians.This Is A New Release Of The Original 1858 Edition.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
