The Third Commandment.
Remember the Sabbath day to keep it holy.
"91] 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. 92] 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.
93] On the contrary, any observance or work that is practised 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."

"95] 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.
96] Therefore not only those sin against this commandment who grossly misuse and desecrate the holy day, as those who on account of their greed or frivolity neglect to hear God's Word or lie in taverns and are dead drunk like swine; but also that other crowd, who listen to God's Word as to any other trifle, and only from custom come to preaching, and go away again, and at the end of the year know as little of it as at the beginning. 97] For hitherto the opinion prevailed that you had properly hallowed Sunday when you had heard a mass or the Gospel read; but no one cared for God's Word, as also no one taught it. Now, while we have God's Word, we nevertheless do not correct the abuse; we suffer ourselves to be preached to and admonished, but we listen without seriousness and care.
98] Know, therefore, that you must be concerned not only about hearing, but also about learning and retaining it in memory, and do not think that it is optional with you or of no great importance, but that it is God's commandment, who will require of you how you have heard, learned, and honored His Word.
99] Likewise those fastidious spirits are to be reproved who, when they have heard a sermon or two, find it tedious and dull, thinking that they know all that well enough, and need no more instruction. For just that is the sin which has been hitherto reckoned among mortal sins, and is called torpor or satiety, a malignant, dangerous plague with which the devil bewitches and deceives the hearts of many, that he may surprise us and secretly withdraw God's Word from us."
"100] For let me tell you this, even though you know it perfectly and be already master in all things, still you are daily in the dominion of the devil, who ceases neither day nor night to steal unawares upon you, to kindle in your heart unbelief and wicked thoughts against the foregoing and all the commandments. Therefore you must always have God's Word in your heart, upon your lips, and in your ears. But where the heart is idle, and the Word does not sound, he breaks in and has done the damage before we are aware. 101] On the other hand, such is the efficacy of the Word, whenever it is seriously contemplated, heard, and used, that it is bound never to be without fruit, but always awakens new understanding, pleasure, and devoutness, and produces a pure heart and pure thoughts. For these words are not inoperative or dead, but creative, living words. 102] And even though no other interest or necessity impel us, yet this ought to urge every one thereunto, because thereby the devil is put to Right and driven away, and, besides, this commandment is fulfilled, and [this exercise in the Word] is more pleasing to God than any work of hypocrisy, however brilliant."
