Melanchthon's views differed from Luther's only in some modifications of ideas. Melanchthon looked upon the law as not only the correlate of the Gospel, by which its effect of salvation is prepared, but as the unchangeable order of the spiritual world which has its basis in God himself. He furthermore reduced Luther's much richer view of redemption to that of legal satisfaction. He did not draw from the vein of mysticism running through Luther's theology, but emphasized the ethical and intellectual elements.
