The “Transubstantiation” is the sacramental act by which the substance of the bread and wine is changed into the substance of the Body and Blood of Christ. Under the consecrated species of bread and wine “CHRIST HIMSELF, LIVING AND GLORIOUS, IS PRESENT IN A TRUE, REAL AND SUBSTANTIAL MANNER: HIS BODY AND HIS BLOOD, WITH HIS SOUL AND HIS DIVINITY” (cf. Council of Trent: DS 1640; 1651).
—Catechism of the Catholic Church
A PRAYER OF FAITH IN THE DIVINE EUCHARIST
I BELIEVE IN MY HEART and openly profess that the bread and wine which are placed upon the altar are by the mystery of the sacred Prayer and the Words of the Redeemer substantially changed into the TRUE and LIFE-GIVING FLESH and BLOOD of JESUS CHRIST Our Lord and after the Consecration, there is present the true Body of CHRIST which was born of the Virgin Mary and offered up for the salvation of the world, hung upon the Cross, and now sits at the right hand of the FATHER and there is present the true Blood of CHRIST which flowed from his side. They are present not only by means of a sign and of the efficacy of the Sacrament, but also in the very reality and truth of their nature and substance. Amen.
