"From Eucharist and prayer they hold aloof, because they do not confess that the Eucharist is the FLESH of our Savior Jesus Christ, which suffered for our sins, and which the Father in His loving-kindness raised from the dead. And so, those who question the gift of God perish in their contentiousness. It would be better for them to have love, so as to share in the resurrection. It is proper, therefore, to avoid associating with such people and not to speak about them either in private or in public, but to study the Prophets attentively and, especially, the Gospel, in which the Passion is revealed to us and the Resurrection shown in its fulfillment. Shun division as the beginning of evil."
-St. Ignatius of Antioch (35-107 A.D.), Bishop and Father of the Church
"I promised you [new Christians], who have now been baptized, a sermon in which I would explain the sacrament of the Lord’s Table. . . . That bread which you see on the altar, having been sanctified by the word of God, is the body of Christ. That chalice, or rather, what is in that chalice, having been sanctified by the word of God, is the blood of Christ"
-Saint Augustine Doctor and one of the four Great Fathers of the Church (Sermons 227 [A.D. 411]).
"We call this food Eucharist, and no one else is permitted to partake of it, except one who believes our teaching to be true and who has been washed in the washing which is for the remission of sins and for regeneration [i.e., has received baptism] and is thereby living as Christ enjoined. For not as common bread nor common drink do we receive these; but since Jesus Christ our Savior was made incarnate by the word of God and had both flesh and blood for our salvation, so too, as we have been taught, the food which has been made into the Eucharist by the Eucharistic prayer set down by him, and by the change of which our blood and flesh is nurtured, is both the flesh and the blood of that incarnated Jesus"
-Saint Justin Martyr, Father of the Church (First Apology 66 [A.D. 151]).
"’Eat my flesh,’ [Jesus] says, ‘and drink my blood.’ The Lord supplies us with these intimate nutrients, he delivers over his flesh and pours out his blood, and nothing is lacking for the growth of his children"
-Saint Clement of Alexandria, Father of the Church (The Instructor of Children 1:6:43:3 [A.D. 191]).
"Perhaps you may be saying, ‘I see something else; how can you assure me that I am receiving the body of Christ?’ It but remains for us to prove it. And how many are the examples we might use! . . . Christ is in that sacrament, because it is the body of Christ"
-Saint Ambrose of Milan (The Mysteries 9:50, 58 [A.D. 390]).
"The bread and the wine of the Eucharist before the holy invocation of the adorable Trinity were simple bread and wine, but the invocation having been made, the bread becomes the body of Christ and the wine the blood of Christ"
-Saint Cyril of Jerusalem (Catechetical Lectures 19:7 [A.D. 350]).
"After having spoken thus [at the Last Supper], the Lord rose up from the place where he had made the Passover and had given his body as food and his blood as drink, and he went with his disciples to the place where he was to be arrested. But he ate of his own body and drank of his own blood, while he was pondering on the dead. With his own hands the Lord presented his own body to be eaten, and before he was crucified he gave his blood as drink"
-Aphraahat the Persian Sage (Treatises 12:6 [A.D. 340]).
"We will necessarily add this also. Proclaiming the death, according to the flesh, of the only-begotten Son of God, that is Jesus Christ, confessing his resurrection from the dead, and his ascension into heaven, we offer the unbloody sacrifice in the churches, and so go on to the mystical thanksgivings, and are sanctified, having received his holy flesh and the precious blood of Christ the Savior of us all. And not as common flesh do we receive it; God forbid: nor as of a man sanctified and associated with the Word according to the unity of worth, or as having a divine indwelling, but as truly the life-giving and very flesh of the Word himself. For he is the life according to his nature as God, and when he became united to his flesh, he made it also to be life-giving"
-Council of Ephesus, Session 1, Letter of Cyril to Nestorius [A.D. 431].
From the Council of Trent. December 13, 1545 to December 4, 1563. Gloriously reigned over by Popes Paul III, Julius III, Pius IV, and attended by about 225 Bishops. It produced 16 Dogmatic documents...
ON THE SACRIFICE OF THE MASS.
CANON I.--If any one saith, that in the mass a true and proper sacrifice is not offered to God; or, that to be offered is nothing else but that Christ is given us to eat; let him be anathema.
CANON II.--If any one saith, that by those words, Do this for the commemoration of me (Luke xxii. 19), Christ did not institute the apostles priests; or, did not ordain that they, and other priests should offer His own body and blood; let him be anathema.
CANON III.--If any one saith, that the sacrifice of the mass is only a sacrifice of praise and of thanksgiving; or, that it is a [Page 159] bare commemoration of the sacrifice consummated on the cross, but not a propitiatory sacrifice; or, that it profits him only who receives; and that it ought not to be offered for the living and the dead for sins, pains, satisfactions, and other necessities; let him be anathema.
CANON IV.--If any one saith, that, by the sacrifice of the mass, a blasphemy is cast upon the most holy sacrifice of Christ consummated on the cross; or, that it is thereby derogated from; let him be anathema.
CANON V.--If any one saith, that it is an imposture to celebrate masses in honour of the saints, and for obtaining their intercession with God, as the Church intends; let him be anathema.
CANON VI.--If any one saith, that the canon of the mass contains errors, and is therefore to be abrogated; let him be anathema.
CANON VII.--If any one saith, that the ceremonies, vestments, and outward signs, which the Catholic Church makes use of in the celebration of masses, are incentives to impiety, rather than offices of piety; let him be anathema.
CANON VIII.--If any one saith, that masses, wherein the priest alone communicates sacramentally, are unlawful, and are, therefore, to be abrogated; let him be anathema.
CANON IX.--If any one saith, that the rite of the Roman Church, according to which a part of the canon and the words of consecration are pronounced in a low tone, is to be condemned; or, that the mass ought to be celebrated in the vulgar tongue only; or, that water ought not to be mixed with the wine that is to be offered in the chalice, for that it is contrary to the institution of Christ; let him be anathema.
