This commandment, therefore, according to its gross sense, does not concern us Christians; for it is altogether an external matter, like other ordinances of the Old Testament, which were attached to particular customs, persons, times, and places, and now have been made free through Christ. But to grasp a Christian meaning for the simple as to what God requires in this commandment, note that we keep holy days not for the sake of intelligent and learned Christians (for they have no need of it [holy days]), but first of all for bodily causes and necessities, which nature teaches and requires; for the common people, man-servants and maid-servants, who have been attending to their work and trade the whole week, that for a day they may retire in order to rest and be refreshed. Secondly, and most especially, that on such day of rest (since we can get no other opportunity) freedom and time be taken to attend divine service, so that we come together to hear and treat of God's and then to praise God, to sing and pray. However, this, I say, is not so restricted to any time, as with the Jews, that it must be just on this or that day; for in itself no one day is better than another; but this should indeed be done daily; however, since the masses cannot give such attendance, there must be at least one day in the week set apart. But since from of old Sunday [the Lord's Day] has been appointed for this purpose, we also should continue the same, in order that everything be done in harmonious order, and no one create disorder by unnecessary innovation. Therefore this is the simple meaning of the commandment: since holidays are observed anyhow, such observance should be devoted to hearing God's Word, so that the special function of this day should be the ministry of the Word for the young and the mass of poor people, yet that the resting be not so strictly interpreted as to forbid any other incidental work that cannot be avoided. Accordingly, when asked, What is meant by the commandment: Thou shalt sanctify the holy day? answer: To sanctify the holy day is the same as to keep it holy. But what is meant by keeping it holy? Nothing else than to be occupied in holy words, works, and life. For the day needs no sanctification for itself; for in itself it has been created holy [from the beginning of the creation it was sanctified by its Creator]. But God desires it to be holy to you. Therefore it becomes holy or unholy on your account, according as you are occupied on the same with things that are holy or unholy. How, then, does such sanctification take place? Not in this manner, that [with folded hands] we sit behind the stove and do no rough [external] work, or deck ourselves with a wreath and put on our best clothes, but (as has been said) that we occupy ourselves with God's Word, and exercise ourselves therein.
