Not Infallible

I find it quite ironic (read "Min Hashamayim") that while the cardinals are attempting to install their "infallible" pope (an oxymoron if I ever heard one), we are in the midst of Parshat Vayikra, where we read:

 אִם הַכֹּהֵן הַמָּשִׁיחַ יֶחֱטָא

and

אֲשֶׁר נָשִׂיא, יֶחֱטָא.

As it says in Kohelet:  כִּי אָדָם, אֵין צַדִּיק בָּאָרֶץ--אֲשֶׁר יַעֲשֶׂה-טּוֹב, וְלֹא יֶחֱטָא.

As the gemara says, there were only 4 people to have ever lived without sinning: Binyamin, Amram, Yishai, and Kil'av.
