Let us return once more to the night of Holy Saturday. In the Creed we say about Christ’s journey that he “descended into hell.” What happened then? Since we have no knowledge of the world of death, we can only imagine his triumph over death with the help of images which remain very inadequate. Yet, inadequate as they are, they can help us to understand something of the mystery. The liturgy applies to Jesus’ descent into the night of death the words of Psalm 23[24]: “Lift up your heads, O gates; be lifted up, O ancient doors!” The gates of death are closed, no one can return from there. There is no key for those iron doors. But Christ has the key. His Cross opens wide the gates of death, the stern doors. They are barred no longer. His Cross, his radical love, is the key that opens them. The love of the One who, though God, became man in order to die – this love has the power to open those doors. This love is stronger than death. The Easter icons of the Oriental Church show how Christ enters the world of the dead. He is clothed with light, for God is light. “The night is bright as the day, the darkness is as light” (cf. Ps 138[139]12).
