Luther and all the Reformers went even further in the marriage question, true enough, only for opportunist reasons, and out of complaisance towards the Princes whose strong support and permanent friendship they sought to secure and keep to the Reformation. The friendly Duke of Hessen, Philip I, had, besides his legitimate wife, a sweetheart, willing to yield to his wishes, but only under the condition that he marry her. It was a thorny problem. A divorce from the wife, in the absence of convincing reasons, would give great scandal; on the other hand, a marriage with two women at a time was an unheard of thing with a Christian Prince of modern days; it would give rise to no less a scandal. All this notwithstanding, Philip, in his passion, decided in favor of the latter step. The point was now to establish that the act did no violence to the Bible, and to secure the approval of the Reformers, especially of Luther and Melanchthon. The negotiations, set on foot by the Duke, began first with Butzer, who declared himself in favor of the plan, and promised to win over Luther and Melanchthon. Butzer justified his opinion with the argument: To possess several wives at once was not against the evangelium. St. Paul, who said much upon the subject of who was not to inherit the kingdom of God, made no mention of those who had two wives. St. Paul, on the contrary, said "that a Bishop was to have but one wife, the same with his servants; hence, if it had been compulsory that every man have but one wife he would have so ordered, and forbidden a plurality of wives." Luther and Melanchthon joined this reasoning, and gave their assent to double marriages, after the Duke's wife herself had consented to the marriage with the second wife under the condition "that he was to fulfil his marital duties towards her more than ever before."[51] The question of the justification of bigamy had before then--at the time when the issue was the consenting to the double marriage of Henry VIII of England--caused many a headache to Luther, as appears from a letter to the Chancellor of Saxony, Brink, dated January, 1524. Luther wrote to him that, _in point of principle, he could not reject bigamy_ because it ran not counter to Holy Writ;[52] but that he held it scandalous when the same happened among Christians, "who should leave alone even things that are permissible." After the wedding of the Duke, which actually took place in March, 1540, and in answer to a letter of acknowledgment from him, Luther wrote (April 10): "That your Grace is happy on the score of our opinion, _which we fain would see kept secret; else, even the rude peasants_ (in imitation of the Duke's example) might finally produce as strong, if not stronger, reasons, whereby we might then have much trouble on our hands."
