Luther's views on this subject, however, were perfectly clear, and he expressed himself accordingly. In his opinion, the answer had been given by the keynote of evangelical teaching. It lay in the distinction between spiritual and temporal government, the essential features of which he had already explained in 1523 in his treatise 'On the Secular Power.' The life of the soul in God, its reconciliation and redemption, its relations and duty to God and fellow-man in faith and love--these are the subjects dealt with in the gospel message of salvation, or the biblical revelation in its completeness. God has left to the practical understanding and needs of man, and to the historical development of peoples and states under His overruling providence, the arrangement of forms of law for social life, without the necessity of any special revelation for that purpose. It is the duty of the secular power to administer the existing laws, and to make new ones in a proper and legal manner, according as they may think fit. That God prescribed to the people of Israel external, civil ordinances by the mouth of Moses, was part of His scheme of education. Christians are not bound by these ordinances,--no more, indeed, than is their inner life and right conduct made conditional on outward rules and forms. Moral commands alone belong to that part of the Mosaic law whereof the sanction is eternal; and to the fulfilment of these commands, written, as St. Paul says, from the beginning on the hearts of men, the Spirit of God now urges His redeemed people. No doubt the law of Moses, in regard to civil life, might contain much that would be useful for other peoples also in that respect. But it would, in that case, be the business of the powers that be to examine and borrow from it, just as Germany borrowed her civil law from the Romans. Such, briefly stated, are the views which Luther enunciated with clearness and consistency, in his writings and sermons. He guards the civil power as jealously now against an irregular assertion of religious principles and biblical authority, as he had formerly done against the aggressions of an ecclesiastical hierarchy, while at the same time he defends the religious life of Christians against the dangers and afflictions which that hierarchy threatened. Thus he answered the prince, on June 18, 1524, to this effect: Temporal laws are something external, like eating and drinking, house and clothing. At present the laws of the Empire have to be maintained, and faith and love can coexist with them very well. If ever the zealots of the Mosaic law become Emperors, and govern the world as their own, they may choose, if they please, the law of Moses; but Christians at all times are bound to support the law which the civil authority imposes.
