It is, however, objected that Cardinal Cajetan, the famous theologian and a contemporary of Luther, had described polygamy as allowable in principle, and that Luther merely followed in his footsteps. But Cajetan does not deny that the prohibition pronounced by the Church stands, he merely deals in scholastic fashion with the questions whether polygamy is a contravention of the natural law, and whether it is expressly interdicted in Holy Scripture. True enough, however, he answers both questions in the negative.[834] In the first everything of course depends on the view taken with regard to the patriarchs and the Old Testament exceptions; the grounds for these exceptions (for such they undoubtedly were) have been variously stated by theologians. In the second, i.e. in the matter of Holy Scripture, Cajetan erred. His views on this subject have never been copied and, indeed, a protest was at once raised by Catharinus, who appealed to the whole body of theologians as teaching that, particularly since the preaching of the Gospel, there was no doubt as to the biblical prohibition.[835] Thus, in spite of what some Protestants have said, it was not by keeping too close to the mediæval doctrine of matrimony, that Luther reached his theory of polygamy. It is more likely that he arrived at it owing to his own arbitrary and materialistic ideas on marriage. It was certainly not the Catholic Church which showed him the way; as she had safeguarded the sanctity of marriage, so also she protected its monogamous character and its indissolubility. In Luther’s own day the Papacy proved by its final pronouncement against the adultery of Henry VIII. of England, that she preferred to lose that country to the Church rather than sanction the dissolving of a rightful marriage (vol. iv., xxi. 1). _Toleration for Concubinage? Matrimony no Sacrament._ In exceptional cases Luther permitted those bound to clerical celibacy, on account of “the great distress of conscience,” to contract “secret marriages”; he even expressly recommended them to do so.[836] These unions, according to both Canon and Civil law, amounted to mere concubinage. Luther admits that he had advised “certain parish priests, living under the jurisdiction of Duke George or the bishops,” to “marry their cook secretly.”[837]
