Earlier in the month, Roger Ebert posted this essay in the wake of Pope Benedict's retirement. It's a thoughtful examination of the development of one man's beliefs. I encourage everyone to read Roger Ebert's blog. I do not always agree with the man, but he expresses himself with clarity, consideration and poise. I respect that quality in anyone. Many of us could emulate Mr. Ebert more in that respect.
Enjoy the reads, and stay tuned for new posts on Wednesday and Friday!
