Feast of the Holy Cross

In the Christian liturgical calendar, there are several different Feasts of the Cross, all of which commemorate the cross used in the crucifixion of Jesus. While Good Friday is dedicated to the Passion of Christ and the Crucifixion, these days celebrate the cross itself, as the instrument of salvation.

In English, it is called The Exaltation of the Holy Cross in the official translation of the Roman Missal, while the 1973 translation called it The Triumph of the Cross. In some parts of the Anglican Communion the feast is called Holy Cross Day, a name also used by Lutherans. The celebration is also sometimes called Holy Rood Day.

As per some Christian tradition the True Cross was discovered in 326 by Saint Helena, the mother of the Roman Emperor Constantine the Great, during a pilgrimage she made to Jerusalem. The Church of the Holy Sepulchre was then built at the site of the discovery, by order of Helena and Constantine. The church was dedicated nine years later, with a portion of the cross. One-third remained in Jerusalem, one-third was brought to Rome and deposited in the Sessorian basilica Santa Croce in Gerusalemme (Holy Cross in Jerusalem), and one-third was taken to Constantinople to make the city impregnable.

The date of the feast marks the dedication of the Church of the Holy Sepulchre in 335. This was a two-day festival: although the actual consecration of the church was on September 13, the cross itself was brought outside the church on September 14 so that the clergy and faithful could pray before the True Cross, and all could come forward to venerate it.
