On the contrary, Jerome says (Ad Hedib., Ep. xxx), "The Lord Jesus Christ, Himself the guest and banquet, is both the partaker and what is eaten."
I answer that, Some have said that Christ during the supper gave His body and blood to His disciples, but did not partake of it Himself. But this seems improbable. Because Christ Himself was the first to fulfill what He required others to observe: hence He willed first to be baptized when imposing Baptism upon others: as we read in Acts 1:1: "Jesus began to do and to teach." Hence He first of all took His own body and blood, and afterwards gave it to be taken by the disciples. And hence the gloss upon Ruth 3:7, "When he had eaten and drunk, says: Christ ate and drank at the supper, when He gave to the disciples the sacrament of His body and blood. Hence, 'because the children partook [*Vulg.: 'are partakers' (Heb. 2:14)] of His flesh and blood, He also hath been partaker in the same.'"
Reply Obj. 1: We read in the Gospels how Christ "took the bread . . . and the chalice"; but it is not to be understood that He took them merely into His hands, as some say, but that He took them in the same way as He gave them to others to take. Hence when He said to the disciples, "Take ye and eat," and again, "Take ye and drink," it is to be understood that He Himself, in taking it, both ate and drank. Hence some have composed this rhyme:
"The King at supper sits,
The twelve as guests He greets,
Clasping Himself in His hands,
The food Himself now eats."
Reply Obj. 2: As was said above (Q. 76, A. 5), Christ as contained under this sacrament stands in relation to place, not according to His own dimensions, but according to the dimensions of the sacramental species; so that Christ is Himself in every place where those species are. And because the species were able to be both in the hands and the mouth of Christ, the entire Christ could be in both His hands and mouth. Now this could not come to pass were His relation to place to be according to His proper dimensions.
Reply Obj. 3: As was stated above (Q. 79, A. 1, ad 2), the effect of this sacrament is not merely an increase of habitual grace, but furthermore a certain actual delectation of spiritual sweetness. But although grace was not increased in Christ through His receiving this sacrament, yet He had a certain spiritual delectation from the new institution of this sacrament. Hence He Himself said (Luke 22:15): "With desire I have desired to eat this Pasch with you," which words Eusebius explains of the new mystery of the New Testament, which He gave to the disciples. And therefore He ate it both spiritually and sacramentally, inasmuch as He received His own body under the sacrament which sacrament of His own body He both understood and prepared; yet differently from others who partake of it both sacramentally and spiritually, for these receive an increase of grace, and they have need of the sacramental signs for perceiving its truth. _______________________
SECOND ARTICLE [III, Q. 81, Art. 2]
Whether Christ Gave His Body to Judas?
Objection 1: It seems that Christ did not give His body to Judas. Because, as we read (Matt. 26:29), our Lord, after giving His body and blood to the disciples, said to them: "I will not drink from henceforth of this fruit of the vine, until that day when I shall drink it with you new in the kingdom of My Father." From this it appears that those to whom He had given His body and blood were to drink of it again with Him. But Judas did not drink of it afterwards with Him. Therefore he did not receive Christ's body and blood with the other disciples.
Obj. 2: Further, what the Lord commanded, He Himself fulfilled, as is said in Acts 1:1: "Jesus began to do and to teach." But He gave the command (Matt. 7:6): "Give not that which is holy to dogs." Therefore, knowing Judas to be a sinner, seemingly He did not give him His body and blood.
