Certianty
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.”
