Photo by Jane WinsteadOn Good Friday, Catholics turn to the Veneration of the Cross to try to understand Christ's sacrifice for our redemption. The practice began in the fourth century in Jerusalem when St. Helen, the mother of Roman emperor Constantine, discovered a fragment of wood believed to the Lord's Holy Cross. The relic was venerated every year on Good Friday. The Church in Rome adopted the practice in the seventh century. Today we kneel before the crucifix and kiss it to pay the highest honor to the Holy Cross as the means of our salvation.
