Only two general causes of full divorce on alleged scriptural authority were thus admitted by Luther and his immediate followers. Other offenses, except as by logical fiction brought under the definition of desertion or adultery, were merely accepted as grounds of temporary separation from bed and board, subject to reconciliation.[182] On the other hand, the representatives of the more liberal tendency anticipated in many ways modern ideas as to the grounds of absolute dissolution of the marriage bond. Avoiding to some extent the indirect method of attaining practical ends by juggling with definitions, they were inclined to appeal for authority directly to Roman imperial legislation; and so, "since the other direction is connected with the canon law, we have here a phase of the struggle" between that system and the Roman jurisprudence.[183] The first step in the liberal direction is taken by Erasmus, who sustains a rational method of dealing with the divorce problem through appeal to the teachings of the early Fathers, notably those of Origen; and this brought him in contact with the principles of the old Roman law.[184] His influence, as Richter strongly urges, seems to have been felt by Zwingli, who, with his disciple Bullinger, argues that in admitting adultery as a cause of divorce the Scriptures sanction as such all equal or graver offenses.[185] Accordingly, in the Zurich marriage ordinance of 1525, "adultery, malicious desertion, and plotting against the life of a consort are not regarded as the only causes, but rather as the standard causes of divorce, and to the judge it is left to decide what others shall be put by their side. And not only this, but cruelty, madness, leprosy, are mentioned as causes which the judge can take into account."[186] Lambert of Avignon is likewise conspicuous for liberal ideas regarding the causes of divorce. Anticipating the principle so often enforced by modern legislation, he holds that when a wife is forced by intolerable suffering to leave the husband who mistreats her and denies her proper support, this should be counted as repudiation by the man, and not as desertion by the woman, who should therefore be allowed to contract another marriage.[187] Similar views are held by Bucer,[188] Melanchthon,[189] and the jurist Monner.[190] All accept the two general causes, and each admits several other grounds.
