The First Holy Communion is an important sacrament that every Catholic child must receive because it unites us to Christ, who shares His Body and Blood with us to form a single body (CCC 1331). Catholic Christians partake in Holy Communion to recognize the Body and Blood of Jesus Christ during the Eucharist through the power of the Holy Spirit and the priest's intercession. Under the appearances of bread and wine — Christ's body, blood, soul, and divinity — the glorified Christ, who rose from the dead, is truly present.
