Did Judas receive the Holy Eucharist, from the hand of Jesus, while in the state of mortal sin?

Judas’s betrayal of Jesus was a grave sin. We know this because the text, "better had he not be born" was written in Matthew 26:24. Ergo, did Jesus give Judas Holy Communion at the Last Supper? No one knows for sure. Both Western and Eastern father disagree. However, here are their theories if Judas received. 

1. NO. In John 13, Judas leaves the last supper before Jesus commences the first Holy Mass. 

• John does not narrate the institution of the Eucharist at the Last Supper. Instead, John describes Jesus giving Judas a dipped morsel, Satan entering Judas, Jesus telling him “what you are going to do, do quickly,” and Judas leaving immediately.

• Only after Judas leaves, does Jesus begin the Farewell Discourse (John 13–17). This is why many Church Fathers:  Augustine, Aquinas, and most Western theologians argue Judas left before the Eucharist. 

2. YES. In the Synoptic Gospels (Matthew, Mark, Luke), Judas is present during both the meal and Eucharist. Furthermore, Luke clocks Judas's kiss after the consecration of Holy Eucharist. After the Eucharist in Luke 22:21–23, Jesus says, “Behold, the hand of him who betrays me is with me on the table.” This is why many Eastern Fathers say Judas received the Eucharist from the hand of Jesus.

• Jesus knew the state of Judas' heart just as He knew the good thief's heart upon death. Sinful hearts may be in the state of remorse at the time of Eucharistic reception. Since Judas was NOT being judged at his particular or final judgement, Jesus was bound by the laws of free will. If Judas did receive Holy Communion, Christ applied the graces of Holy Communion to save Judas’ soul. 

• The graces of Holy Communion were accepted by Judas initially, since he returned the 30-pieces of silver later (Mt 27:3-4). If so, this precedence is used by some priests, to not judge Holy Communicants who are presumed to be in the state of grave sin. 

Summary

Did Judas receive Holy Communion from Jesus' hand in the state of mortal sin? You decide. No matter what happened, Christ respected Judas’s free will, just as he respects our free will until the time of our judgement. Below are the church fathers' responses to the title question. 

No --  John: Judas leaves before anything like the Eucharist happens.

No --  Augustine & Aquinas: Judas did not receive (follows John).

Yes -- Matthew: Betrayal is announced, then the Eucharist; Judas is not said to leave.

Yes -- Mark: Same as Matthew; Judas is not said to leave.

Yes -- Luke: Eucharist  is followed by the betrayer’s hand on the table — Judas is clearly still there.

Yes -- Chrysostom & Cyril: Say Judas did receive (follows Luke).
