Above all things, I most affectionately and for God’s sake beseech all, who see or desire to observe this our Order of Divine Service, on no account to make of it a compulsory law, or to ensnare or make captive thereby any man’s conscience; but to use it agreeably to Christian liberty at their good pleasure as, where, when and so long as circumstances favour and demand it. Moreover, we would not have our meaning taken to be that we desire to rule, or by law to compel, any one. Meanwhile, there is on every side great pressure towards a German Mass and Order of Divine Service: and there is great complaint and offence about the different kinds of new Masses, that every one makes his own, some with a good intention and others out of conceit to introduce something new themselves and to make a good show among others and not be bad masters. As then always happens with Christian liberty, few use it for anything else than their own pleasure or profit: and not for God’s honour and the good of their neighbour. While, however, every man is bound on his conscience, in like manner as he uses such liberty himself, not to hinder nor forbid it to any one else, we must also take care that liberty be servant to love and to our neighbour. Where, then, it happens that men are offended or perplexed at such diversity of use, we are truly bound to put limits to liberty; and, so far as possible, to endeavour that the people are bettered by what we do and not offended. Since, then, in these matters of outward ordinance nothing is laid upon us as matter of conscience before God, and yet such ordinance can be of use to our neighbour, we ought in love, as St. Paul teaches, to endeavour to be of one and the same mind; and, to the best of our power, of like ways and fashion; just as all Christians have one baptism and one sacrament, and no one has a special one given him of God.
Still, I do not wish hereby to demand that those who already have a good Order or, by God’s grace, can make a better, should let it go, and yield to us. Nor is it my meaning that the whole of Germany should have to adopt forthwith our Wittenberg Order. It never was the case that the ministers, convents, and parishes were alike in everything. But it would be a grand thing if, in every several lordship, Divine Service were conducted in one fashion; and the neighbouring little townships and villages joined in the cry with one city. Whether in other lordships they should do the same or something different, should be left free and without penalty. In fine, we institute this Order not for the sake of those who are Christians already. For they have need of none of these things (for which things’ sake man does not live: but they live for the sake of us who are not yet Christians, that they may make us Christians); they have their Divine Service in their spirits. But it is necessary to have such an Order for the sake of those who are to become Christians, or are to grow stronger; just as a Christian has need of baptism, the word and the sacrament not as a Christian (for, as such, he has them already), but as a sinner. But, above all, the Order is for the simple and for the young folk who must daily be exercised in the Scripture and God’s Word, to the end that they may become conversant with Scripture and expert in its use, ready and skilful in giving an answer for their faith, and able in time to teach others and aid in the advancement of the kingdom of Christ. For the sake of such, we must read, sing, preach, write, and compose; and if it could in any wise help or promote their interests, I would have all the bells pealing, and all the organs playing, and everything making a noise that could. The Popish Divine Services are to be condemned for this reason that they have made of them laws, work, and merit; and so have depressed faith. And they do not direct them towards the young and simple, to practise them thereby in the Scripture and Word of God; but they are themselves stuck fast in them, and hold them as things useful and necessary to salvation : and that is the devil. For in this wise the ancients have neither ordered nor imposed them. Now there are three different kinds of Divine Service.
[I] The first, in Latin; which we published lately, called the Formula Missae. This I do not want to have set aside or changed; but, as we have hitherto kept it, so should we be still free to use it where and when we please, or as occasion requires. I do not want in anywise to let the Latin tongue disappear out of Divine Service; for I am so deeply concerned for the young. If it lay in my power, and the Greek and Hebrew tongues were as familiar to us as the Latin, and possessed as great a store of fine music and song as the Latin does, Mass should be held and there should be singing and reading, on alternate Sundays in all four languages-German, Latin, Greek and Hebrew. I am by no means of one mind with those who set all their store by one language, and despise all others; for I would gladly raise up a generation able to be of use to Christ in foreign lands and to talk with their people, so that we might not be like the Waldenses in Bohemia whose faith is so involved in the toils of their own language that they can talk intelligibly and plainly with no one unless he first learn their language. That was not the way of the Holy Ghost in the beginning. He did not wait till all the world should come to Jerusalem, and learn Hebrew. But He endowed the office of the ministry with all manner of tongues, so that the Apostles could speak to the people wherever they went. I should prefer to follow this example; and it is right also that the youth should be practised in many languages. Who knows how God will make use of them in years to come? It is for this end also that schools are established.
 Next, there is the German Mass and Divine Service, of which we are now treating. This ought to be set up for the sake of the simple laymen. Both these kinds of Service then we must have held and publicly celebrated in church for the people in general. They are not yet believers or Christians. But the greater part stand there and gape, simply to see something new: and it is just as if we held Divine Service in an open square or field amongst Turks or heathen. So far it is no question yet of a regularly fixed assembly wherein to train Christians according to the Gospel: but rather of a public allurement to faith and Christianity.
 But the third sort [of Divine Service], which the true type of Evangelical Order should embrace, must not be celebrated so publicly in the square amongst all and sundry. Those, however, who are desirous of being Christians in earnest, and are ready to profess the Gospel with hand and mouth, should register their names and assemble by themselves in some house to pray, to read, to baptize and to receive the sacrament and practise other Christian works. In this Order, those whose conduct was not such as befits Christians could be recognized, reproved, reformed, rejected, or excommunicated, according to the rule of Christ in Matt. xviii. Here, too, a general giving of alms could be imposed on Christians, to be willingly given and divided among the poor, after the example of St. Paul in 2 Cor. ix. Here there would not be need of much fine singing. Here we could have baptism and the sacrament in short and simple fashion: and direct everything towards the Word and prayer and love. Here we should have a good short Catechism about the Creed, the Ten Commandments, and the Lord’s Prayer. In one word, if we only had people who longed to be Christians in earnest, Form and Order would soon shape itself. But I cannot and would not order or arrange such a community or congregation at present. I have not the requisite persons for it, nor do I see many who are urgent for it. But should it come to pass that I must do it, and that such pressure is put upon me as that I find myself unable with a good conscience to leave it undone, then I will gladly do my part to secure it, and will help it on as best I can. In the meantime, I would abide by the two Orders aforesaid; and publicly among the people aid in the promotion of such Divine Service, besides preaching, as shall exercise the youth and call and incite others to faith, until those Christians who are most thoroughly in earnest shall discover each other and cleave together; to the end that there be no faction-forming, such as might ensue if I were to settle everything out of my own head. For we Germans are a wild, rude, tempestuous people; with whom one must not lightly make experiment in anything new, unless there be most urgent need. Well, then: in the name of God. The first requisite in the German system of Divine Worship is a good, plain, simple, and substantial Catechism. A Catechism is a form of instruction by which heathen, desirous of becoming Christians, are taught and shown what they are to believe, to do, to leave undone and to know in Christianity. Hence mere learners who were admitted to such instruction, and were acquiring the rudiments of the Christian faith before their baptism were called catechumens. This instruction or information I know no better way of putting than that in which it has been put from the beginning of Christianity till today: I mean, in those three articles of the Ten Commandments, the Creed, and the Lord’s Prayer. In those three articles is contained, plainly and briefly, all that a Christian needs to know.
