The Sacrament of the Holy Eucharist is the source and summit of the Christian life. The other sacraments, and other ministries and works of Catholic people, are bound together and oriented toward the Holy Eucharist.
At Mass, the bread and wine is changed into the total Jesus Christ, body and blood, soul and divinity. Holy Communion unites us intimately with Jesus Christ, separates us from sin, and unites with other members of the Catholic Church. Catholics normally receive the Holy Eucharist at Mass unless they need to go to Reconciliation to seek forgiveness of their serious sins.
