... this week is Bright Week in the Eastern Catholic Church with today being Bright Tuesday... "from the holy day of the Resurrection of Christ our God until New Sunday (i.e. Thomas Sunday) for a whole week the faithful in the holy churches should continually be repeating psalms, hymns and spiritual songs, rejoicing and celebrating Christ, and attending to the reading of the Divine Scriptures and delighting in the Holy Mysteries. For in this way shall we be exalted with Christ; raised up together with Him."
During all of Bright Week the Holy Doors on the Iconostasis are kept open—the only time of the year when this occurs. The open doors represent the stone rolled away from the Tomb of Christ, and the Epitaphios (Slavonic: Plashchanitza), representing the burial clothes, is visible through them on the Holy Table (altar). The doors are closed before the Ninth Hour on the eve of Thomas Sunday. However, the Afterfeast of Pascha will continue until the eve of the Ascension.
