The priest should, therefore, study to reproduce in his own soul the things that are effected upon the Altar. As Jesus Christ immolates Himself, so His minister should be immolated with Him; as Jesus expiates the sins of men, so he, by following the hard road of Christian asceticism, should labor at the purification of himself and of others. Hence the admonition of St. Peter Chrysologus: “Be you the priest and the sacrifice of God; do not lose that which has been given to you by the authority of God. Clothe yourself with the garment of sanctity, gird yourself with the cincture of chastity; let Christ be the covering for your head; let the cross of Christ be the protection before your face; instill in your breast the sacrament of divine wisdom; constantly burn the incense of prayer; grasp the sword of the Spirit; let your heart be, as it were, an altar on which you may safely offer your body as a victim to God . . . Offer Him your faith, for the chastisement of perfidy; offer Him your fasting, that gluttony may cease; offer your chastity as a sacrifice that passion may die; place on the Altar your piety, that impiety be put away; call upon mercy, that avarice may be overcome; and that folly may disappear, the immolation of sanctity is called for. In this way shall your body be also your victim, if it has not been wounded by any dart of sin”.41Sermo CVIIIs Migne, P.L., LII, 500, 501.
