(CNN) -- One of the Bible's paradoxical statements comes from St. Paul's Epistle to the Galatians: "Power is made perfect in infirmity."
The poetic statement proclaims that when we are weak, we are strong. Pope Benedict XVI's stepping down from what many consider one of the most powerful positions in the world proves it. In a position associated with infallibility -- though that refers to formal proclamations on faith and morals -- the pope declares his weakness.
His acceptance of frailty speaks realistically about humanity: We grow old, weaken, and eventually die. A job, even one guided by the Holy Spirit, as we Roman Catholics believe, can become too much for us.
Acceptance of human frailty has marked this papacy. We all make mistakes, but the pope makes them on a huge stage.
