There is a famous quote attributed to then-Cardinal Joseph Ratzinger in 1997, in comments to a Bavarian television station. The future Pope Benedict XVI said the Holy Spirit acted like a good educator in a conclave, allowing cardinals to freely choose a pope without dictating the precise candidate.

Two cardinals, Michael Czerny and Chibly Langlois, sat down with ABC News to discuss the challenges facing the church that the new pope will have to face.

Cardinals who will take part in the secret conclave to elect a new Catholic pope began checking into two Vatican hotels on Tuesday, where they will be barred from contact with the outside world as they decide who should succeed Pope Francis.
