They say that you need to know when you can't do what you do any more. The Pope has come to that realization.
Pope Benedict had to follow in the footsteps of someone who was being called a saint while he was still alive. He then worked to deal with the fall-out of the homosexual pedophile priests in America, the slow disintegration of the church liturgy and other problems that had been put on the back burner for decades. He advocated for greater punishment for child abuse in any form, assisted in bringing back the Traditional Latin Mass to America, and pushed for other reforms too many to list.
He's done an admirable job. And now he's giving up power, willingly, because he knows that he cannot adequately fulfill the position in his physical condition.
That, my friends, is humility. We all know people who refuse to give up any power, no matter how small or how little. And here's a man who is giving up being the leader of over a BILLION people world wide, a man who holds a position of incomparable influence, for the good of that organization.
We can only hope that the next Pope comes close to who Pope Benedict is.
