Luther knew that it was certainly contrary to his duty to God to violate the solemn vows he had made to God, and still more so, to take a Nun from her Convent as his wife. As for love of God, Jesus invited His Apostles to love Him so much as to leave aside all attachment to father, mother, wife, or children, in order the more closely to follow Him. He blessed marriage for such as are called to that state. But He Himself did not marry, nor did His Apostles after they were called to the ministry.
