“In the first part we shall consider which persons may enter into marriage with one another. In order to proceed aright let us direct our attention to Genesis 1[:27], “So God created man … male and female he created them.” From this passage we may be assured that God divided mankind into two classes, namely, male and female, or a he and a she. This was so pleasing to him that he himself called it a good creation [Gen. 1:31]. Therefore, each one of us must have the kind of body God has created for us. I cannot make myself a woman, nor can you make yourself a man; we do not have that power. But we are exactly as he created us: I a man and you a woman. Moreover, he wills to have his excellent handiwork honored as his divine creation, and not despised. The man is not to despise or scoff at the woman or her body, nor the woman the man. But each should honor the other’s image and body as a divine and good creation that is well-pleasing unto God himself” (Luther’s Works, vol. 45, p.17).
