On Great and Holy Saturday the Church observes the day on which Christ reposed in the tomb. Foreshadowing this day as the blessed the seventh day, by Moses, the Church sees it the Blessed Sabbath. In other words, this is the day of rest on which the only-begotten Son of God rested from all His works (Vesperal Liturgy of Holy Saturday).
By calling this day the Blessed Sabbath the Church links Holy Saturday with the creative act of God. In the account of creation in the Book of Genesis, God made man in His own image and likeness, and to be truly himself, man was to live in everlasting communion with the dynamic power of that image: God. When humankind fell from God, that image was broken.
By His Holy Resurrection, the Logos (Word), the Son of God through whom all things were created, has come to restore us to communion with God. He has thereby completed creation, and all things are as the Father intended. Having consummated this great act, He rests from all His works, and this day is forever known as the Blessed Sabbath.
