The olden Church sought to permeate the world with the religious spirit. Luther’s trend was in a great measure towards making the secular state and its office altogether independent; this, indeed, the more up-to-date sort of ethics is disposed to reckon among his greatest achievements. Luther even went so far as to seek to erect into a regular system this inward, necessary opposition of world and Church. Of this we have a plain example in certain of his instructions to the authorities.[204] Whereas the Church had exhorted people in power to temper with Christianity their administration of civil justice and their use of physical force—urging that the sovereign was a Christian not merely in his private but also in his official capacity,—Luther tells the ruler: The Kingdom of Christ wholly belongs to the order of grace, but the kingdom of the world and worldly life belong to the order of the Law; the two kingdoms are of a different species and belong to different worlds. To the one you belong as a Christian, to the other as a man and a ruler. Christ has nothing to do with the regulations of worldly life, but leaves them to the world; earthly life stands in no need of being outwardly hallowed by the Church.[205] Certain statements to a different effect will be considered elsewhere. “A great distinction,” Luther said in 1523, “must be made between a worldling and a Christian, i.e. between a Christian and a worldly man. For a Christian is neither man nor woman ... must know nothing and possess nothing in the world.... A prince may indeed be a Christian, but he must not rule as a Christian, and when he rules he does so not as a Christian but as a prince. As an individual he is indeed a Christian, but his office or princedom is no business of his Christianity.” This seems to him proved by his mystical theory that a Christian “must not harm or punish anyone or revenge himself, but forgive everyone and endure patiently all injustice or evil that befalls him.” The theory, needless to say, is based on his misapprehension of the Evangelical Counsels which he makes into commands.[206] On such principles as these, he concludes, it was impossible for any prince to rule, hence “his being a Christian had nothing to do with land and subjects.”[207]
