Pope Shenouda III
The cross is used in all the holy Sacraments in Christianity
All the Sacraments sprang from the merit of Christ's blood on the Cross. Had it not been for the Cross, we would never have been worthy to approach God as His children in the Sacrament of Baptism, we would never have been worthy to partake of His Body and Blood in the Sacrament of the Eucharist (1Cor.11: 26), nor would we have been able to enjoy the graces of any of the Church Sacraments.
