Luther himself had written, that “a boy ought to have recourse to matrimony as soon as he is twenty and a maid when she is from fifteen to eighteen years of age, and leave it to God to provide for their maintenance and that of their children.”[178] Other adherents of the new faith went even further, Eberlin of Günsburg simply declared: “As soon as a girl is fifteen, a boy eighteen, they should be given to each other in marriage.” There were others like the author of a “Predigt über Hunger- und Sterbejahre, von einem Diener am Wort” (1571), who raised strong objections against such a course. Dealing with the causes of the evident increase of “deterioration and ruin” in “lands, towns and villages,” he says, that “a by no means slight cause is the countless number of lightly contracted marriages, when people come together and beget children without knowing where they will get food for them, and so come down themselves in body and soul, and bring up their children to begging from their earliest years.” “And I cannot here approve of this sort of thing that Luther has written: A lad should marry when he is twenty, etc. [see above]. No, people should not think of marrying and the magistrates should not allow them to do so before they are sure of being able at least to provide their families with the necessaries of life, for else, as experience shows, a miserable, degenerate race is produced.”[179] What this old writer says is borne out by modern sociologists. One of them, dealing with the 16th and 17th centuries, says: “These demands [of Luther and Eberlin] are obviously not practicable from the economic point of view, but from the ethical standpoint also they seem to us extremely doubtful. To rush into marriage without prospect of sufficient maintenance is not trusting God but tempting Him. Such marriages are extremely immoral actions and they deserve legal punishment on account of their danger to the community.” “Greater evil to the world can scarcely be caused in any way than by such marriages. Even in the most favourable cases such early marriages must have a deteriorating influence on the physical and intellectual culture of posterity.”[180] Owing to the neglect of any proper care for the poor the plague of vagabondage continued on the increase. Luther’s zealous contemporary, Cyriacus Spangenberg, sought to counteract it by reprinting the Master’s edition of the “_Liber vagatorum_.” He says: “False begging and trickery has so gained the upper hand that scarcely anybody is safe from imposture.” The Superintendent, Nicholas Selnecker, again republished the writing with Luther’s preface in 1580, together with some lamentations of his own. He complains that “there are too many tramps and itinerant scholars who give themselves up to nothing but knavery,” etc.[181]
