In Luther’s denial of the sacramental character of matrimony lies the key to the arbitrary manner in which, as shown by the above, he handled the old ecclesiastical marriage law. It was his ruling ideas on faith and justification which had led him to deny that it was a sacrament. The sacraments, in accordance with this view, have no other object or effect than to kindle in man, by means of the external sign, that faith which brings justification. Now marriage, to his mind, was of no avail to strengthen or inspire such faith. As early as 1519 he bewails the lack in matrimony of that Divine promise which sets faith at work (“_quae fidem exerceat_”),[843] and in his Theses of February 13, 1520, he already shows his disposition to question its right to be termed a sacrament.[844] In his work “On the Babylonish Captivity” of the same year he bluntly denies its sacramental character, urging that the Bible was silent on the subject, that matrimony held out no promise of salvation to be accepted in faith, and finally that it was in no way specifically Christian, since it had already existed among the heathen.[845] He ignores all that the Fathers had taught regarding marriage as a sacrament, with special reference to the passage in Ephesians v. 31 ff., and likewise the ancient tradition of the Church as retained even by the Eastern sects separated from Rome since the fifth century. In advocating matrimony, instead of appealing to it as a sacrament, he lays stress on its use as a remedy provided by God against concupiscence, and on its being the foundation of that family life which is so pleasing to God. Incidentally he also points out that it is a sign of the union of Christ with the congregation.[846] Luther did not, as has been falsely stated, raise marriage to a higher dignity than it possessed in the Middle Ages. No more unjustifiable accusation has been brought against Catholic ages than that marriage did not then come in for its due share of recognition, that it was slighted and even regarded as sinful. Elsewhere we show that the writings dating from the close of the Middle Ages, particularly German sermonaries and matrimonial handbooks, are a direct refutation of these charges.[847] _Luther on Matters Sexual._
