In a manner described by the Church hymn, He ‘ministered to Himself,’ and, as the true Paschal Lamb for the faithful for whom He was prepared to sacrifice Himself, He offered Himself prior to the event. During the Supper, Jesus took a loaf from the table (Greek: artos, indicating leavened bread), blessed it, broke it, and distributed it among the disciples, saying, ‘Take, eat, this is My Body, which is given for you; do this in My remembrance.’ At the conclusion of the meal, He took the fifth cup of thanksgiving, mixed with wine and water, and rendered thanks before giving it to them, saying: ‘Drink from it, all of you, for this is My blood of the New Covenant, which is poured out for you and many for the forgiveness of sins; do this, as often as you drink it, in My remembrance.’ As St. John Chrysostom interprets, ‘He Himself was the first to partake and drink His own blood’; following Him, the others then drank from the cup. This cup represented the Eucharistic cup, the cup of the blood of the New Covenant. The teaching that emerged after the Supper (Luke 22:20) occurred in the absence of Judas the betrayer, who could not partake in the covenant of Christ's redeeming blood. The phrase ‘after the Supper’ aligns with the timing of the sacrament's establishment identified by the Apostle Paul and corroborated by St. John concerning Judas’s departure. The Apostle Paul indicates that Christ instituted the sacrament on the night of His betrayal, aligning this with Luke's testimony that it happened post-Supper. The accuracy with which the Apostle Paul conveys this event is validated by his direct revelation from the Lord (1 Cor. 11:23-25). This moment of sacrament institution aligns with John’s account of Judas’s exit: ‘He (Judas), having received the bread, went out immediately; and it was night’ (John 13:30). Together, these accounts from the two Evangelists and the Apostle Paul specify the exact point of the Eucharist's institution: it was after the Old Testament Passover and following Judas's betrayal, never prior. Jesus celebrated the last Old Testament Passover for Israel at evening (Matt. 26:20; Mark 14:17), concluding the Old Testament era. Subsequently, the New Covenant is established with the sacrament of Christ's body and blood, the holy Eucharist. The institution of this sacrament occurred after the Supper, at night (Lk. 22:20; 1 Cor. 11:23, 25; Jn. 13:30). Thus, the new covenant emerges—not based on the blood of the Old Testament lamb but on the true blood of Christ. According to St. John Chrysostom, the Apostles, ‘having heard enough about this sacrament previously, approached the sacred meal with reverence and faith,’ with none of the confusion previously evident during the Capernaum discourse (John 6:60). The Lord’s disciples now grasped that His flesh is indeed food, and His blood is indeed drink, believing that all His teachings, especially regarding this sacrament, carry spirit and life (v. 55:63). The words by which the Savior instituted the sacrament leave no room for doubt: ‘If the Lord Himself declared of the bread, 'This is My Body,’ who would dare to question this? And if He affirmed, ‘This is My Blood,’ who would dispute it?’ (St. Cyril of Jerusalem). Furthermore, as St. Philaret of Moscow elucidates, ‘the Lord did not declare of the sacramental bread, “Take, eat all of you,” making exceptions for those unqualified such as infants; however, in regards to the sacramental cup, He commanded, “Drink from it, all of you,” thereby removing all exclusions for those who remain in the faith and unity of the Church.’ The command given by the Savior to observe this sacrament in His memory has been faithfully maintained by the holy Apostles in the Church, which is evident in the Acts of the Apostles where the first Christians devoted themselves to the Apostles' teachings, fellowship, the breaking of bread, and prayers (2:42), customarily gathering for the breaking of bread on the first day of the week (20:7). The Apostle Paul, called later to the apostolate and not present at the Last Supper, received divine revelation, and in his letters, he provided comprehensive guidance on how to partake of the Lord's Supper appropriately while expressing firm confidence in the continuation of the Eucharist until the Lord's return (1 Corinthians 11:20-30). The Holy Eucharistic Supper marked the final earthly meal of the Lord: ‘I tell you, I will not drink of this fruit of the vine from now on until that day when I drink it new with you in the kingdom of My Father.’ This conveys a profound mystery related to the sacrament of the Eucharist, commemorating the atoning sacrifice Jesus rendered for the sins of humanity. Judas, being unrepentant, was unworthy to participate in this sacred act of communion, leading the Lord to exclude him. Thus, the holy Church instructs that the reception of sacraments should follow an authentic practice of Penance. Without genuine reflection during confession, one approaches the body and blood of Christ inadequately prepared. Monk Ambrosius of Optina remarks, ‘There are Christians who repent yet fail to express their all in confession; some sins remain concealed out of shame. Such individuals, as per the Apostle's admonition, unworthily partake of the holy sacraments, incurring various afflictions, and many even face death. The Apostle states, ‘Whoever eats and drinks unworthily eats and drinks judgment to himself, not discerning the body of the Lord’ (1 Cor. 11:29). Concealed sin leads to spiritual death and physical suffering, ‘as punishment arises not only from sins but more so from the unworthy reception of the holy sacraments.’ It is advised to receive the sacraments only when the heart is pure (St. John Chrysostom). Venerable Simeon the New Theologian warns that body and blood are sacraments welcomed by an unworthy soul, perceived only in semblance rather than essence. The Angel of God stands by the Chalice, and those deemed unworthy do not receive true Communion from God. The angel carries the Holy Gifts to the altar, and when the unworthy communicant departs from the Cup, they are accompanied not by a good Angel, but by a demon, leading to their condemnation in communion. The priest carries some burden as well, as he did not ensure proper confession or guidance. He offers communion visible to the Angel, yet one should prepare for receiving the holy sacrament through repentance, fasting, and prayer. A fast of three or four days is recommended. On the eve of Communion, one ought to attend the evening service and engage in additional evening prayers, such as the penitential canon, as well as specific prayers to the Mother of God and Guardian Angel. The prayers that constitute the Consecration for Holy Communion should also be recited. In these, believers beseech the Lord for an ‘uncondemned communion with Thy pure, deathless, life-giving, and awe-inspiring sacraments, for the remission of sins and eternal life.’
