"In the celebration of this we believe that our Lord Jesus Christ is present, not figuratively, or in an image, or by superabundant grace, as in the other mysteries, nor by a simple presence, as some of the Fathers have said concerning Baptism, nor by conjunction, as that the Deity of the Word is personally united to the bread of the Eucharist which is set forth, as the LUTHERANS MOST IGNORANTLY AND MISERABLY THINK; but really and actually, so that after the consecration of the bread and the wine the bread is changed, TRANSUBSTANTIATED, transmade, and reordered, into the real body of the Lord itself, which was born in Bethlehem of the Ever-Virgin, was baptized in Jordan, suffered, was buried, rose, ascended, sitteth at the right hand of God the Father, and will come on the clouds of heaven; and the wine is transmade and TRANSUBSTANTIATED into the real blood of the Lord itself, which was poured forth for the life of the world when He hung on the cross.
Further, we believe that after the consecration of the bread and the wine the SUBSTANCE of the bread and the wine NO LONGER REMAINS, but there is the body itself and the blood of the Lord in the species and form of the bread and the wine, that is to say, under the ACCIDENTS of the bread. Further, that the all-pure body itself and blood of the Lord are distributed and enter the mouth and stomach of the communicants, both pious and impious, only they convey to the pious and worthy remission of sins and eternal life, but they involve to the impious and unworthy condemnation and eternal punishment.
Further that the body and the blood of the Lord are severed and divided by the hands and teeth by way of ACCIDENT, that is, in the ACCIDENTS of the bread and the wine, in which they are acknowledged to be visible and tangible, while in themselves they remain altogether unsevered and undivided. Wherefore also the Catholic Church says, 'He is separated and distributed who being separated is not divided, who is ever eaten and never consumed, but sanctifies those who partake' [from the Liturgy of St. Basil and St. John Chrysostom], that is, worthily.
Further, that in every part and the smallest fragment of the changed bread and wine there is not a part of the body and blood of the Lord, for that would be blasphemous and wicked, but the whole Lord Christ wholly in SUBSTANCE, that is, with His soul and Godhead, perfect God and perfect Man. Wherefore, though there may be many celebrations in the world at one and the same hour, there are not many Christs or many bodies of Christ, but one and the same Christ is present really and actually, and His body and His blood are one in all the several churches of the faithful; and this not because the body of the Lord which is in heaven descends on the altars but because the bread which is offered and set forth in all the several churches, being transmade and TRANSUBSTANTIATED, becomes and is after the consecration one and the same as that which is in heaven. For the body of the Lord is one in many places, and not many bodies....
Further, that the body itself and the blood of the Lord which are in the mystery of the Eucharist ought to be honored in the highest way, and WORSHIPPED WITH DIVINE ADORATION. For the WORSHIP of the Holy Trinity and of the body and blood of the Lord is ONE. Further, that it is a REAL AND PROPITIATORY SACRIFICE offered for all the orthodox living and dead, and for the benefit of all....Further, that before the use immediately after the consecration and after the use that which is kept in the holy pyxes for the reception of those who are about to depart is the real body of the Lord, and not in any respect different from it; so that before the use after the consecration, in the use, and after the use, it is altogether the real body of the Lord.
Further, that by the word TRANSUBSTANTIATION the manner in which the bread and the wine are transmade into the body and blood of the Lord is not explained; for this is altogether incomprehensible and is impossible except for God Himself; and attempts at explanation bring Christians to folly and error. But the word denotes that the bread and the wine after the consecration are changed into the body and blood of the Lord not figuratively or by way of image or by superabundant grace or by the communication or presence of the Deity alone of the Only Begotten. Neither is any ACCIDENT of the bread and of the wine transmade in any way or by any change into any ACCIDENT of the body and blood of Christ; but REALLY AND ACTUALLY AND SUBSTANTIATIALLY the bread becomes the real body of the Lord itself, and the wine the blood of the Lord itself, as has been said above."
