“Thou shalt not take the name of the Lord thy God in vain.” An elderly doctor is approached by a woman with a complicated request. Her husband is gravely ill and may die, and she is pregnant by someone else. If her husband dies, she wants to keep the child, but not otherwise, and she wants the doctor to give him an honest verdict on his chances. But the doctor is disturbed by her request, because his answer will directly affect the life or death of another human being. Is he entitled to play God?
