"The essence of Christianity is, therefore, nothing else than Christ Himself. The founder of the religion is Himself, its sum and substance. He is not merely the historical founder of a religion; His person cannot be separated from the doctrine which he proclaims, but has an eternal, ever-present significance for the human race. As he is the Mediator and Propitiator, the sacred point of unity between God and the sinful world, so He is also continually the Redeemer of the human race. All regenerating, all purifying, all sanctifying influences by which man is freed from his state of bondage to sin, and made to partake of the mystery of the incarnation and atonement, proceed from the person of Christ, through the Spirit going out from Him into His Church." (Martensen, Dogmatics §15)
