By Regis Martin, National Catholic Register - Does life come with a set of instructions on how to live it? And if so, who wrote them? By whose authority are the instructions to be followed? Options are fairly limited here, reducing either to God, who inscribed them into the very constitution of our being, or ourselves, who more or less make things up as we go along. We write the constitution, adding numberless amendments along the way. Are we aiming to hit the bullseye of beatitude, or do we fall headlong into hell? It hardly matters so long as we get to call the shots.
