And, indeed, we Christians ought always to keep such a holy day, and be occupied with nothing but holy things, i.e., daily be engaged upon God's Word, and carry it in our hearts and upon our lips. But (as has been said) since we do not at all times have leisure, we must devote several hours a week for the sake of the young, or at least a day for the sake of the entire multitude, to being concerned about this alone, and especially urge the Ten Commandments, the Creed, and the Lord's Prayer, and thus direct our whole life and being according to God's Word. At whatever time, then, this is being observed and practiced, there a true holy day is being kept; otherwise it shall not be called a Christians' holy day. For, indeed, non-Christians can also cease from work and be idle, just as the entire swarm of our ecclesiastics, who stand daily in the churches, singing, and ringing bells but keeping no holy day holy, because they neither preach nor practices God's Word, but teach and live contrary to it. For the Word of God is the sanctuary above all sanctuaries, yea, the only one which we Christians know and have. For though we had the bones of all the saints or all holy and consecrated garments upon a heap, still that would help us nothing; for all that is a dead thing which can sanctify nobody. But God's Word is the treasure which sanctifies everything, and by which even all the saints themselves were sanctified. At whatever hour then, God's Word is taught, preached, heard, read or meditated upon, there the person, day, and work are sanctified thereby, not because of the external work, but because of the Word which makes saints of us all. Therefore I constantly say that all our life and work must be ordered according to God's Word, if it is to be God-pleasing or holy. Where this is done, this commandment is in force and being fulfilled. On the contrary, any observance or work that is practiced without God's Word is unholy before God, no matter how brilliantly it may shine! even though it be covered with relics, such as the fictitious spiritual orders which know nothing of God's Word and seek holiness in their own works. Note, therefore, that the force and power of this commandment lies not in the resting but in the sanctifying so that to this day belongs a special holy exercise. For other works and occupations are not properly called holy exercises, unless the man himself be first holy. But here a work is to be done by which man is himself made holy, which is done (as we have heard ) alone through God's Word. For this, then, fixed places, times, persons, and the entire external order of worship have been created and appointed, so that it may be publicly in operation.
