The cross has been a symbol of the church from the early years of Catholicism to the present. No catholic church will not carry a cross, either on its tower, the door and especially the altar. The crucifix is a cross with the image of the Savior Lord Jesus Christ nailed to it. This sacrament can be seen in various forms and sizes, and is highly revered by devout Catholics. In praying before the cross or crucifix we Catholics remember the suffering and sacrifice of the life of Christ.
