Why is receiving Communion vital to the Catholic faith?

Holy Communion is “the source and summit of the Christian Life.” (CCC 1324). The Apostles and earliest Christian communities joined in community for celebration of the Eucharist. In the Acts of the Apostles, we read, “They devoted themselves to the teaching of the apostles and to the communal life, to the breaking of the bread and to the prayers” (Acts 2:42). St. Paul also refers to the celebration of communion, writing, “The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ?” (1 Corinthians 10:16).

Jesus chose such a moment to reveal his identity soon after the resurrection, following his journey alongside two travelers on the road to Emmaus: “And it happened that, while he was with them at table, he took bread, said the blessing, broke it, and gave it to them. With that their eyes were opened and they recognized him, but he vanished from their sight… Then the two recounted what had taken place on the way and how he was made known to them in the breaking of the bread” (Luke 24: 30-31, 35).
