Philip was affected by Melanchthon's opinion concerning the case of Henry VIII, where the Reformer had proposed that the king's difficulty could be solved by his taking a second wife better than by his divorcing the first one. To strengthen his position, there were Luther's own statements in his sermons on the Book of Genesis, as well as historical precedents which proved to his satisfaction that it was impossible for anything to be un-Christian that God had not punished in the case of the patriarchs, who in the New Testament were held up as models of faith. It was during an illness due to his excesses that the thought of taking a second wife became a fixed purpose.
