“When you buy an automobile, the manufacturer gives you a set of instructions.  He tells you the pressure to which you ought to inflate your tires, the kind of oil you ought to use in the crankcase, and the proper fuel to put in the gas tank.  He has nothing against you by giving you these instructions as God had nothing against you in giving you commandments.  The manufacturer wants to be helpful; he is anxious that you get the maximum utility out of the car.  And God is anxious that we get the maximum happiness out of life.  Such is the purpose of His commandments.”  Archbishop Fulton Sheen (Preface to Religion)
