Let us prepare for union
The Eucharist unites us to Christ directly; this physical union is the same for all who partake of His Body and Blood. However, it does not produce the same effects in everyone. This is so true that the Sacrament may even become a cause of damnation for those who approach it unworthily: “Whosoever shall eat this bread or drink the chalice of the Lord unworthily,” says St. Paul, “eateth and drinketh judgment to himself” (1 Corinthians 11:27-29).
