Ascension of Jesus to facilitate the obligation to attend Mass. Saint Jerome held that it was of Apostolic origin, but in fact the ascension was originally part of Pentecost (the coming of the Holy Spirit), and developed as a separate celebration only slowly from the late 4th century onward. In the Catholic tradition it begins with a three-day "rogation" to ask for God's mercy, and the feast itself includes a procession of torches and banners symbolising Christ's journey to the Mount of Olives and entry into heaven, the extinguishing of the Paschal candle, and an all-night vigil; white is the liturgical colour. The
Epitaphios (liturgical) left in the empty tomb (). During Bright Week (Easter Week), the Holy Doors of the sanctuary remain open as a symbol of the empty tomb of Christ. The Epitaphios is clearly visible through the open doors, and thus symbolizes the winding sheet left in the tomb after the resurrection. At the end of Bright Week, the Holy Doors are closed, but the Epitaphios remains on the Holy Table for 40 days, as a reminder of Jesus' physical appearances to his disciples from the time of his Resurrection until his Ascension into heaven. An Epitaphios of the Theotokos also exists.
