The one who approaches the table of the Lord without being hungry and thirsty for Christ’s pardon, eats and drinks unworthily. The person who thinks he or she is in order before God and with people and has no need to be reconciled with anyone, eats and drinks unworthily. The one who thinks he owes nobody anything and almost believes that it is God who owes him something for coming to church and for making an effort to approach the Eucharistic table, eats and drinks unworthily. Presuming to think that one is worthy of the Eucharist opens the door to a self-sufficiency and self-satisfaction which makes the Eucharist almost useless because it no longer is seen as a uniquely, infinitely great gift before which we must always fall down in grateful adoration.
