What is more insane than to be partakers of the Sacraments of the Lord and not partakers of the words of the Lord? These men truly have to say: "In Thy Name we have eaten and drunk," and they will have to hear: "I do not know you!" (Luke 13:26-27). They eat and drink His Body and Blood in the Sacrament and do not recognize in the Gospel His members spread over the whole world, and for this reason they are not numbered among them at the Judgment.
