XVI. Lo! where are the idle ones, who do not know how to do good works? Where are they who run to Rome, to St. James, hither and thither? Take up this one single work of the mass, look on your neighbor's sin and ruin, and have pity on him; let it grieve you, tell it to God, and pray over it. Do the same for every other need of Christendom, especially of the rulers, whom God, for the intolerable punishment and torment of us all, allows to fall and be misled so terribly. If you do this diligently, be assured you are one of the best fighters and captains, not only against the Turks, but also against the devils and the powers of hell. But if you do it not, what would it help you though you performed all the miracles of the saints, and murdered all the Turks, and yet were found guilty of having disregarded your neighbor's need and of having thereby sinned against love? For Christ at the last day will not ask how much you have prayed, fasted, pilgrimaged, done this or that for yourself, but how much good you have done to others, even the very least.
Now without doubt among the "least" are also those who are in sin and spiritual poverty, captivity and need, of whom there are at present far more than of those who suffer bodily need. Therefore take heed: our own self-assumed good works lead us to and into ourselves, that we seek only our own benefit and salvation; but God's commandments drive us to our neighbor, that we may thereby benefit others to their salvation. Just as Christ on the Cross prayed not for Himself alone, but rather for us, when He said, "Father, forgive them, fort they know not what they do," so we also must pray for one another. From which every man may know that the slanderers, frivolous judges and despisers of other people are a perverted, evil race, who do nothing else than heap abuse on those for whom they ought to pray; in which vice no one is sunk so deep as those very men who do many good works of their own, and seem to men to be something extraordinary, and are honored because of their beautiful, splendid life in manifold good works.
XVII. Spiritually understood, this Commandment has a yet far higher work, which embraces the whole nature of man. Here it must be known that in Hebrew " Sabbath " means " rest," because on the seventh day God rested and ceased from all His works, which He had made. Genesis ii. Therefore He commanded also that the seventh day should be kept holy and that we cease from our works which we do the other six days. This Sabbath has now for us been changed into the Sunday, and the other days are called work-days;the Sunday is called rest-day or holiday or holy day. And would to God that in Christendom there were no holiday except the Sunday; that the festivals of Our Lady and of the Saints were all transferred to Sunday; then would many evil vices be done away with through the labor of the work-days, and lands would not be so drained and impoverished. But now we are plagued with many holidays, to the destruction of souls, bodies and goods; of which matter much might be said.
This rest or ceasing from labors is of two kinds, bodily and spiritual. For this reason this Commandment is also to be understood in two ways.
The bodily rest is that of which we have spoken above, namely, that we omit our business and work, in order that we may gather in the church, see mass, hear God's Word and make common prayer.
This rest is indeed bodily and in Christendom no longer commanded by God, as the Apostle says, Colossians ii, "Let no man obligate you to any holiday whatever" -- for they were of old a figure, but now the truth has been fulfilled, so that all days are holy days, as Isaiah says, chapter lxvi, "One holy day shall follow the other"; on the other hand, all days are workdays. Yet it is a necessity and ordained by the Church for the sake of the imperfect laity and working people, that they also may be able to come to hear God's Word. For, as we see, the priests and clergy celebrate mass every day, pray at all hours and train themselves in God's Word by study, reading and hearing. For this reason also they are freed from work before others, supported by tithes and have holy-day every day, and every day do the works of the holy-day, and have no work-day, but for them one day is as the other. And if we were all perfect, and knew the Gospel, we might work every day if we wished, or rest if we could. For a day of rest is at present not necessary nor commanded except only for the teaching of God's Word and prayer.
The spiritual rest, which God particularly intends in this Commandment, is this: that we not only cease from our labor and trade, but much more, that we let God alone work in us and that we do nothing of our own with all our powers. But how is this done? In this way: Man, corrupted by sin, has much wicked love and inclination toward all sins, as the Scriptures say, Genesis viii, "Man's heart and senses incline always to the evil," that is, to pride, disobedience, anger, hatred, covetousness, unchastity, etc., and summa summarum, in all that he does and leaves undone, he seeks his own profit, will and honor rather than God's and his neighbor's. Therefore all his works, all his words, all his thoughts, all his life are evil and not godly.
Now if God is to work and to live in him, all this vice and wickedness must be choked and up-rooted, so that there may be rest and a cessation of all our works, thoughts and life, and that henceforth (as St. Paul says, Galatians ii.) it may be no longer we who live, but Christ Who lives, works and speaks in us.
