Reply Obj. 7: Where it could be done without danger, the Church gave order for that thing to be used which more expressively represents Christ's Passion. But there was not so much danger regarding the body which is placed on the corporal, as there is with the blood contained in the chalice. And consequently, although the chalice is not made of stone, yet the corporal is made of linen, since Christ's body was wrapped therein. Hence we read in an Epistle of Pope Silvester, quoted in the same distinction: "By a unanimous decree we command that no one shall presume to celebrate the sacrifice of the altar upon a cloth of silk, or dyed material, but upon linen consecrated by the bishop; as Christ's body was buried in a clean linen winding-sheet." Moreover, linen material is becoming, owing to its cleanness, to denote purity of conscience, and, owing to the manifold labor with which it is prepared, to denote Christ's Passion.
Reply Obj. 8: The dispensing of the sacraments belongs to the Church's ministers; but their consecration is from God Himself. Consequently, the Church's ministers can make no ordinances regarding the form of the consecration, and the manner of celebrating. And therefore, if the priest pronounces the words of consecration over the proper matter with the intention of consecrating, then, without every one of the things mentioned above—namely, without house, and altar, consecrated chalice and corporal, and the other things instituted by the Church—he consecrates Christ's body in very truth; yet he is guilty of grave sin, in not following the rite of the Church. _______________________
FOURTH ARTICLE [III, Q. 83, Art. 4]
Whether the Words Spoken in This Sacrament Are Properly Framed?
Objection 1: It seems that the words spoken in this sacrament are not properly framed. For, as Ambrose says (De Sacram. iv), this sacrament is consecrated with Christ's own words. Therefore no other words besides Christ's should be spoken in this sacrament.
Obj. 2: Further, Christ's words and deeds are made known to us through the Gospel. But in consecrating this sacrament words are used which are not set down in the Gospels: for we do not read in the Gospel, of Christ lifting up His eyes to heaven while consecrating this sacrament: and similarly it is said in the Gospel: "Take ye and eat" (comedite) without the addition of the word "all," whereas in celebrating this sacrament we say: "Lifting up His eyes to heaven," and again, "Take ye and eat (manducate) of this." Therefore such words as these are out of place when spoken in the celebration of this sacrament.
Obj. 3: Further, all the other sacraments are ordained for the salvation of all the faithful. But in the celebration of the other sacraments there is no common prayer put up for the salvation of all the faithful and of the departed. Consequently it is unbecoming in this sacrament.
Obj. 4: Further, Baptism especially is called the sacrament of faith. Consequently, the truths which belong to instruction in the faith ought rather to be given regarding Baptism than regarding this sacrament, such as the doctrine of the apostles and of the Gospels.
Obj. 5: Further, devotion on the part of the faithful is required in every sacrament. Consequently, the devotion of the faithful ought not to be stirred up in this sacrament more than in the others by Divine praises and by admonitions, such as, "Lift up your hearts."
Obj. 6: Further, the minister of this sacrament is the priest, as stated above (Q. 82, A. 1). Consequently, all the words spoken in this sacrament ought to be uttered by the priest, and not some by the ministers, and some by the choir.
