The dictionary defines rape as forced sexual relations against a person's will. By this definition it is possible for a man to rape his wife. However, given Paul's statements, it should not be against a wife's will to have sex with her husband. Therefore, if such an event happens, sin rests with the wife who is resisting fulfilling her duty in marriage. Sin also lies with the husband who is forcing sexual relations. Spousal rape is not a case where only one person is guilty of a sin.
