In The Philosophy of the Christian Religion, Fairbairn considers the problem and the mystery of the person of Christ in the Christian religion. He divides his text into three books. The first contextualizes his argument and addresses questions in the philosophy of nature and mind which affect belief in the supernatural person. In Book II, Fairbairn discusses the person of Christ and the making of the Christian religion in three parts: first, he considers Christ as the founder of Christianity as a historical and as a supernatural person with physical and ethical transcendence.
