'I know by experience that the greatest punishment that can befall a people is a bad priest. It is best to leave a town without a priest than to send one who is unworthy. If God does not send me men who are truly called, God himself will have to take care of the men and souls by means of his angels. A call is God's gift. I must not bring the unworthy into the sheepfold to destroy it instead of tending it.'
