The Feast of the Exaltation of the Holy Cross celebrates three historical events: the finding of the True Crossby Saint Helena, the mother of the emperorConstantine; the dedication of churches built by Constantine on the site of the Holy Sepulchre and Mount Calvary; and the restoration of the True Cross to Jerusalem by the emperor Heraclius II. But in a deeper sense, the feast also celebrates the Holy Cross as the instrument of our salvation. This instrument of torture, designed to degrade the worst of criminals, became the life-giving tree that reversed Adam's Original Sin when he ate from the Tree of the Knowledge of Good and Evil in the Garden of Eden.
