Excerpts from Kennedy's letter to Pope Benedict XVI - CNN.com: "'I pray that you have all of God's blessings as you lead our Church and inspire our world during these challenging times. I am writing with deep humility to ask that you pray for me as my own health declines. I was diagnosed with brain cancer more than a year ago, and although I continue treatment the disease is taking its toll on me. I am 77 years old, and preparing for the next passage of life."
