The Sacrament of the Holy Eucharist is the heart and summit of the Church's life. The Eucharist is the source of community within the Church. The essential signs of the sacrament are wheat bread and grape wine, on which the blessing of the Holy Spirit is invoked during the Sacrifice of the Mass. The bread and wine through Transubstantiation become the Body and Blood, Soul and Divinity of Jesus Christ. We receive the Real Presence of Jesus when we receive Holy Communion. Our soul is nourished, helping us to become like Christ. Receiving Holy Communion with others during the Sacrifice of the Mass brings unity of the Church, the Body of Christ.
