Holy Saturday (Latin: Sabbatum Sanctum), sometimes known as Easter Eve or Black Saturday, is the day after Good Friday. It is the day before Easter and the last day of Holy Week in which Christians prepare for Easter. It commemorates the day that Jesus Christ's body laid in the tomb.
Holy Saturday is sometimes called Easter Saturday, though this phrase is more correctly applied to the Saturday in Easter Week.
The traditional, liturgical observation of Easter, as practised among Roman Catholics and some Lutherans and Anglicans begins on the night of Holy Saturday with the Easter Vigil. This, the most important liturgy of the year, begins in total darkness with the blessing of the Easter fire, the lighting of the large Paschal candle (symbolic of the Risen Christ) and the chanting of the Exultet or Easter Proclamation attributed to Saint Ambrose of Milan. After this service of light, a number of readings from the Old Testament are read, these tell the stories of creation, the sacrifice of Isaac, the crossing of the Red Sea, and the foretold coming of the Messiah. This part of the service climaxes with the singing of the Gloria and the Alleluia and the proclamation of the Gospel of the resurrection. At this time, the lights are brought up and the church bells are rung, according to local custom. A sermon may be preached after the gospel. Then the focus moves from the lectern to the font. Anciently, Easter was considered the ideal time for converts to receive baptism, and this practice continues within Roman Catholicism and the Anglican Communion. Whether there are baptisms at this point or not, it is traditional for the congregation to renew the vows of their baptismal faith. This act is often sealed by the sprinkling of the congregation with holy water from the font. The Catholic sacrament of Confirmation is also celebrated at the Vigil.
