Christianity is Christianity by this one fundamental truth, that as God is the father of man, so truly, and not poetically, or metaphorically only, man is the son of God, participating in God's very essence and nature, though separated from God by self and sin. This oneness of nature between the Divine and the human does not lower the concept of God by bringing it nearer to the level of humanity; on the contrary, it raises the old concept of man and brings it nearer to its true ideal. The true relation between God and man had been dimly foreseen by many prophets and poets, but Christ was the first to proclaim that relation in clear and simple language. He called Himself the Son of God, and He was the firstborn son of God in the fullest sense of that word. But He never made Himself equal with the Father in whom He lived and moved and had His being. He was man in the new and true sense of the word, and in the new and true sense of the word He was God. To my mind man is nothing if He does not participate in the Divine. _Chips._ True Christianity lives, not in our belief, but in our love, in our love of God, and in our love of man founded on our love of God. _Chips._ True Christianity, I mean the religion of Christ, seems to me to become more and more exalted the more we know and the more we appreciate the treasures of truth hidden in the despised religions of the world. But no one can honestly arrive at that conviction unless he uses honestly the same measure for all religions. _Science of Religion._ The position which Christianity from the very beginning took up with regard to Judaism served as the first lesson in comparative theology, and directed the attention even of the unlearned to a comparison of two religions, differing in their conception of the Deity, in their estimate of humanity, in their motives of morality, and in their hope of immortality, yet sharing so much in common that there are but few of the psalms and prayers in the Old Testament in which a Christian cannot heartily join even now, and but few rules of morality which he ought not even now to obey. _Science of Religion._ It was exactly because the doctrine of Christ, more than that of the founders of any other religion, offered in the beginning an expression of the highest truths in which Jewish carpenters, Roman publicans, and Greek philosophers could join without dishonesty, that it has conquered the best part of the world. It was because attempts were made from very early times to narrow and stiffen the outward expression of our faith, to put narrow dogma in the place of trust and love, that the Christian Church often lost those who might have been its best defenders, and that the religion of Christ has almost ceased to be what, before all things, it was meant to be, a religion of world-wide love and charity. _Hibbert Lectures._
