Until such “congregations apart” had come into being the service, and particularly the sermon, according to Luther, must needs be addressed to all. “Such a service there must be for the sake of those who are yet to become Christians, or need strengthening ... especially for the sake of the simple-minded and young ... on their account we must read, sing and preach ... and, where this helps at all, I would have all the bells rung and all the organs played.” He boasts of having been the first to impart to public worship this aim and character, “to exercise the young and to call and incite others to the faith”; the “popish services,” on the other hand, were “so reprehensible” because of the absence of any such character.—In his Churches he sees “many who do not yet believe and are no Christians; the greater part stand there gaping at the sight of something new, just as though we were holding an open-air service among the Turks or heathen.” Hence it seems to him quite necessary to regard the worship in common as simply a public encouragement to faith and Christianity.[523] As for those Christians who already believed, Luther cannot loudly enough assert their freedom. As his highest principle he sets up the following, which in reality is subversive of all liturgy: In Divine worship “it is a matter for each one’s conscience to decide how he is to make use of such freedom [the freedom of the Christian man given by the Evangel]; the right to use it is not to be refused or denied to any.... Our conscience is in no way bound before God by this outward order.”[524] This has the true Lutheran ring. Beside this must be placed his frequently repeated assertion, that we can give God nothing that tends to His honour, and that every effort on our part to give Him anything is merely an attempt to make something of man and his works, which works are invariably sinful.[525] He also teaches elsewhere that not only does real and true worship consist in a life of faith and love, but that the outward worship given in common is in reality a sacrifice of praise and thanksgiving (a gift to God after all) made in common solely because of all people’s need to express their faith and love;[526] he also calls it a “_sacrificium_,” naturally, not in the Catholic, but in the widest sense of the word. Even the expression “eucharistic sacrifice,” i.e. sacrifice of praise, is not inacceptable to him; but at least the sacrifice must be entirely free.
