Sins Against the Eucharist are the Most Grevious of Sins

For anyone with any concern or interest in the Church the link below is a must hear. This is a sermon by an FSSP priest delivered on Sunday, June 26, the Feast of Corpus Christi. He points out that since the Eucharist is our greatest good to which we are indebted it stands that the greatest punishments from Heaven are reserved for those who receive Communion with the guilt of mortal sin on their conscience. (e.g. having engaged in fornication with the practice of birth control, immodesty, etc., without confession) According to St. Cyril of Alexandria people who receive Communion this way are throwing Christ to the infernal lions to be abused:

“They who make a sacrilegious Communion receive Satan and Jesus Christ into their hearts – Satan, that they may let him rule, and Jesus Christ, that they may offer Him in sacrifice as a Victim to Satan.” -- St Cyril of Alexandria

Upon consecration of the bread and chalice at Mass the substance of bread and wine ceases to exist and becomes the very substance of Jesus Christ without sharing in any other substance. The acknowledgment of this supernatural Mystery is the first and foremost requirement placed on us by the Church in order to receive Holy Communion, without which one may not receive Communion.

Should one approach the Communion rail in denial of this Dogma the verdict of Holy Scripture applies: "Therefore whosoever shall eat of this bread, or drink the chalice of the Lord unworthily, shall be guilty of the Body and the Blood of the Lord... For he that eateth and drinketh unworthily, eateth and drinketh judgment to himself, not discerning the Body of the Lord." (1 Corinthians 11: 27, 28)
