Neither public houses of ill fame, nor indeed any form of allurement to vice, is so pernicious as are these vows and commandments invented by Satan himself.”[303] Such are his words in his “Postils,” written for general, practical use. His “larger Catechism” was also used as a means to render popular his most extravagant polemics on this subject. The sixth Commandment makes of chastity a duty, and Christ’s counsel of voluntary continence was to serve for the preserving and honouring of this very command. Yet Luther says: “By this commandment all vows of unmarried chastity are condemned, and all poor, enslaved consciences which have been deceived by their monastic vows are thereby permitted, nay ordered, to pass from the unchaste to the conjugal state, seeing that even though the monastic life were in other particulars divine, it is not in their power to preserve their chastity intact.”[304] Thus “the married state” is, at least, according to this passage, prescribed for all without exception in the Ten Commandments. Still further to strengthen his seductive appeals to the clergy and religious, Luther, as he himself informs us, advised those who were unable to marry openly “at least to wed their cook secretly.”[305] To the Prince-Abbots he gave the advice that on account of the laws of the Empire they should, for the time being, “take a wife in secret,” “until God, the Lord, shall dispose matters otherwise.” In 1523 he advised all the Knights of the Teutonic Order, who were vowed to chastity, “not to worry” about their “weakness and sin” even though they had contracted some “illicit connections”; such connections contracted outside of matrimony were “less sinful” than to “take a lawful wife” with the consent of a Council, supposing such a permission were given.[306] This last letter, too, was at once printed by Luther for distribution.[307] His spirit of defiance led him to clothe his demands in outrageous forms. On one occasion he declared in language resembling that which he made use of concerning the laws of fasting: “Even though a man has no mind to take a wife he ought, nevertheless, to do so in order to spite and vex the devil and his doctrine.”[308]
