"Over the course of many years in the service of our mother the Church, let me tell you — there is one sin which I have come to fear above all others: Certainty. Certainty is the great enemy of unity. Certainty is the deadly enemy of tolerance. Even Christ was not certain at the end: "" he cried out, in his agony, at the ninth hour on the Cross. Our faith is a living thing precisely because it walks hand-in-hand with doubt. If there was only certainty and no doubt, there would be no mystery. And therefore no need for faith. Let us pray that God will grant us a Pope who doubts. And let him grant us a Pope who sins and asks for forgiveness and who carries on."
