“My brothers and sisters, in the course of a long life in the service of our Mother the Church, let me tell you that the one sin I have come to fear more than any other is certainty. Certainty is the great enemy of unity. Certainty is the deadly enemy of tolerance. Even Christ was not certain at the end. 'Eli Eli, lama sabachtani?' He cried out in His agony at the ninth hour on the cross. 'My God, my God, why have you forsaken me?' Our faith is a living thing precisely because it walks hand in hand with doubt. If there was only certainty, and if there was no doubt, there would be no mystery, and therefore no need for faith.” 

I enjoyed this book SO MUCH. I wasn't sure going in if I was going to get in over my head, but it was so interesting and accessible and pretty easy to follow, and just an awesome inside look into the inner workings of a conclave, which let's be honest, is just fascinating from a planning perspective, as well as delving into the real humanity of the characters. Strong recommend. 

I had no idea this was based on a book until I saw the movie nominated for best adapted screenplay at the Oscars. I haven't seen the movie but I'm sure the book was better.
