St. John Vianney
“Listen well so that you may understand your cruelty towards Jesus Christ. What would you say of a man whose father was about to be led to the place of execution, if he found that the executioners had not the power to hang him, should say to them: ‘You have not the strength. Here are my arms, let them serve you to hang my father’? Such an action would make you shudder with horror. That would be as it should be. Ah, well, if I dare, I would say to you that that is still nothing if we compare it with the appalling crime those commit who communicate unworthily. What indeed is natural death, even violent death, if we compare it to that which the sinner inflicts on Jesus Christ in the Eucharistic.”
