It has its origin in Jerusalem and marks the anniversary of the consecration of the basilica built by Emperor Constantine, in order to protect the holy places linked with the passion, death and resurrection by which Jesus Christ redeemed the world and brought to completion the paschal mystery of his death and resurrection. The original basilica included the Martyrium church, the rock of Golgotha and the Anastasis dome with the Edicule of the Resurrection. This day is also linked with the finding of the Holy Cross of the Lord and with the anniversary of the consecration of the temple of Solomon. This new basilica was the occasion to create a new type of liturgy. The liturgical action of Jerusalem adapts itself and is inspired to the mystery which it celebrates and renews. That is why the feast of the Exaltation of the Cross was given great importance and could be compared to Easter and Epiphany for the solemnity of its celebration.
