Christ committed adultery first of all with the woman at the well about whom St. John tells us. Was not everybody about Him saying: "Whatever has he been doing with her?" Secondly, with Mary Magdalene, and thirdly with the woman taken in adultery whom he dismissed so lightly. Thus even Christ, who was so righteous, must have been guilty of fornication before He died. (D. Martin Luthers Werke, kritische Gesamtausgabe [Hermann Bohlau Verlag, 1893], vol. 2, no. 1472, April 7 - May 1, 1532, p. 33)
Jesus was The Innocent Lamb and had not sinned.
1 Peter 2:22He committed no sin, neither was deceit found in his mouth.
Not so with Martin.
