When the priest celebrates the Liturgy of the Presanctified Gifts during the Great Fast (Lent), before the Our Father is sung, he prays, “O God of mysteries beyond human thought and vision ... you have revealed to us the service of this liturgy.” This does not mean that the Presanctified Liturgy was revealed directly by God, but it is perfectly understandable why it would be considered divinely and not humanly inspired. This Liturgy may certainly be considered a manifestation of the Christian genius of the Eastern Church of Constantinople, a part of its theological and liturgical heritage.
The Presanctified Liturgy is celebrated during the Great Fast for two reasons: the necessity of abstinence and the need for nourishment. The Great Fast is a time when we have the opportunity to become aware of our complete dependence on God and our need for redemption. The secular world today, which is very commercial, is suspicious of that message, it wants us to feel good about ourselves so that we become contented consumers. However, the story of Adam and Eve reveals the human choice to put ourselves and our own self-image before God, who created us to be in his image and likeness. Fasting in itself cannot save us, but only reveal how dependent we are on God, because we are able to undertake it only by his grace. However, it makes it possible for him to free us from slavery to our own desires, leaving us open to his activity in the depths of our souls.
One of the most wondrous truths about God is his ability to bring good out of evil, faith out of doubt, hope out of despair, love out of hatred, life out of death. The Presanctified Liturgy is a penitential rite in which we humble ourselves before God through the gesture of prostration, but are exalted as his people through our union with his eucharist. Therefore, we continue to pray before the Our Father: “With Christ Your Word living in us, and walking in our midst, O Lord, may we become the temple of Your all-holy and adorable Spirit.”
