Robert Green Ingersoll suggests that the concept of the atonement is simply an extension of the Mosaic tradition of blood sacrifice and "is the enemy of morality". The death of Jesus Christ represents the blood sacrifice to end all blood sacrifices; the resulting mechanism of atonement by proxy through that final sacrifice has appeal as a more convenient and much less costly approach to redemption than repeated animal sacrifice—a common sense solution to the problem of reinterpreting ancient religious approaches based on sacrifice.
