First Holy Communion
Catholics believe the Eucharist, or Communion, is both a sacrifice and a meal. We believe in the real presence of Jesus, who died for our sins. As we receive Christ's Body and Blood, we also are nourished spiritually and brought closer to God.
Even though we are required to receive Communion at least once per year (our Easter Duty), the Church urges us to receive Communion frequently (even daily, if possible).
Because of the intimate connection of the Sacrament of Holy Communion to our life in Christ, we must be free of any grave or mortal sin before receiving it, as St. Paul explained in 1 Corinthians 11:27-29. Otherwise, as he warns, we receive the Sacrament unworthily, and we "eateth and drinketh damnation" to ourselves.
If we are aware of having committed a mortal sin, we must participate in the Sacrament of Reconciliation first. The Church sees the two Sacraments as connected and urges us, when we can, to join frequent Reconciliation with frequent Communion.
