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.
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.
Since,therefore,so much depends upon God's Word that without it no holy day can be sanctified,we must know that God insists upon a strict observance of this commandment,and will punish all who despise His Word and are not willing to hear and learn it,especially at the time appointed for the purpose.
