At Thy Mystical Supper, O Son of God
A Meditation for Great and Holy Thursday
“For I have received of the Lord that which also I delivered unto you…” (1 Corinthians 11:23)
On this sacred day – Great and Holy Thursday – we stand not merely as readers of Scripture but as participants in the Mystery. Today, the Church brings us into the Upper Room, into Gethsemane, and even to the threshold of Calvary. We do not merely remember. We commune.
The Apostle Paul’s words, passed down as tradition received directly from the Lord Himself, are not dry recollections of a distant event. They are living liturgy. For what Christ instituted on this night – the Mystical Supper – is made present at every Holy Liturgy. And this Supper is not mere symbol, but the true and mystical participation in the once-for-all Sacrifice of the Cross.
“Do this for the commemoration of Me” – The Mystical Supper and the Living Tradition
St. Paul makes a striking claim: “I have received of the Lord…” He was not present at the Last Supper, yet by divine revelation, he receives the very same Mystery that the Apostles did. This shows that what Christ instituted that night was not confined to a moment – it is a continual, living reality, handed down through the Apostolic Church.
At every Liturgy, we hear and sing:
“At Thy Mystical Supper, O Son of God, accept me today as a communicant…”
This is no poetic embellishment. It is a confession of the Real Presence and the reality of communion with the crucified and risen Christ. The Upper Room is mystically extended to every faithful altar.
The faithful will recognize this hymn not only today, but every time they prepare for Holy Communion. For this prayer, which has pride of place throughout today’s liturgy, continues to echo throughout the entire year in the hearts of the faithful.
“For I will not reveal Thy mystery to Thine enemies” – A Warning and a Confession
This hymn of the Mystical Supper is both a plea and a warning. The language is stark: “Thine enemies,” “the kiss of Judas.” These are not distant figures. They are archetypes of every age.
How often have we seen those who outwardly participate in the Sacraments, yet inwardly betray them through unbelief, heresy, or spiritual indifference? Let us not assume that only the Sanhedrin or Judas qualify as enemies of the Mystery. Every irreverent communicant, every unrepentant soul, every clergyman who treats the altar as common ground, stands in that tragic lineage.
Yet the hymn offers hope:
“But like the thief do I confess Thee…”
The path to salvation tonight is the path of the penitent thief, the path of humble confession: “Remember me, O Lord.”
“Ye are clean – but not all” – The Washing of Feet and the Trial of Conscience
In the Gospel for today, Our Lord stoops to wash His disciples’ feet. It is a moment of humility, yes – but more than that, it is a moment of purification.
“He that is washed, needeth not but to wash his feet, but is clean wholly. And you are clean: but not all.” (John 13:10)
Terrifying words. Even among the Twelve, not all were clean. Even at that Mystical Supper, there was one who harbored betrayal.
So too St. Paul warns:
“Whosoever shall eat this bread, or drink the chalice of the Lord unworthily, shall be guilty of the body and of the blood of the Lord.” (1 Corinthians 11:27)
To come to the Eucharist is to make the choice between salvation and condemnation. This is why the Church, in her timeless wisdom, preserves the pre-Communion prayer: “I believe, O Lord, and I confess…” and calls us to examine our hearts.
“Let our mouths be filled with Thy praise” – The Liturgy as Continuation of the Supper
On Holy Thursday, the usual Cherubic Hymn and other prayers are replaced with:
“Of Thy Mystical Supper, O Son of God…”
These are not liturgical novelties. They are mystical proclamations of what is unfolding. Tonight is not yet Pascha. The light of the Resurrection is hidden. Tonight is a night of surrender and intimacy. A night of trembling reverence.
Christ shares His Body and Blood – and then goes forth to be betrayed. We are not yet singing triumph. We are singing faith amidst the shadow.
Conclusion: “Not my will, but Thine be done” – The Eucharist and Gethsemane
In Gethsemane, we hear:
“And being in an agony, he prayed the longer… and his sweat became as drops of blood.” (Luke 22:44)
The Eucharist leads us into Gethsemane, and Gethsemane into the Cross. So too in our lives: the true reception of the Mystical Supper leads us not into ease, but into surrender, suffering, and obedience.
This is the Eucharistic life:
- To confess Christ like the thief
- To be washed and remain clean
- To partake worthily, trembling and full of faith
- To reject the kiss of betrayal and embrace the tears of repentance
Let us, then, come to Him with open hearts – not casually, not presumptuously, but with fear and faith. And let us pray:
“O Son of God, accept me today as a communicant…
“Remember me, O Lord, when Thou comest in Thy Kingdom.”
Amen.
