Ques.—Did Judas Iscariot ever partake of the Lord’s Supper?
Ans.—It seems quite plain from John 13:30 that Judas was not there when the Lord instituted His supper, which took place only at the end of the Passover Supper, The sop was given while the Passover Supper was going on.

In Matt. 26, Judas’ exit would be between vers. 25, 26; in Mark 14, between vers. 21, 22. Luke alone presents a little difficulty by speaking of Judas (chap. 22:21) after mentioning the Lord’s Supper (vers. 19, 20) There need be no difficulty, however, as in all kinds of narratives cer¬tain details which occurred between the great facts are often mentioned at the end only, when all the facts them¬selves have been told.

We may  therefore conclude  from  John   13:30  that   our Lord’s words in Luke 22:21-23 were uttered somewhere during the Passover Supper, before He instituted the re¬membrance of Himself in what is called “the Lord’s Supper.”

We would add, in warning, that some have sought to place Judas at the Lord’s Supper as a precedent for the unholy, yet sadly frequent, practice of allowing evil men to partake of that Supper. All Scripture condemns this; I Cor. deals expressly with it (chap. 5) ; Christian holiness revolts against it. Besides, even if it could be shown that Judas participated in the Lord’s Supper, it would be no precedent for this evil practice, for Judas was not yet manifested, and it is when manifested the Lord requires ex¬pulsion of the evil out of His house.
