BY SACRAMENTALS we mean the various prayers, blessings, ceremonies and pious practices of the Church. Here mention will be made of some of the most common of the sacramentals that have not already been treated. Sacramentals, like sacraments, have an outward sign; the latter, however, were instituted by Christ, the former by the Church, and while the latter always give grace if we place no obstacle in the way, the former do not give grace, but excite good thoughts, increase devotion, and raise the mind to God. The chief sacramentals that have not been mentioned are the books used by the priest in the performance of his sacred duties, the sign of the cross, holy water, blessed candles, blessed palm and ashes, holy oils, scapulars, medals, Agnus Dei, prayers, litanies, rosary, the Angelus, stations, the funeral service, and various blessings. The books used by the priest in the performance of his sacred duties are the _Missal_, which contains the Masses for the various feasts of the ecclesiastical year; the _Breviary_, in which is the office recited by the priest every day; and the _Ritual_, where is to be found the form of administering the different sacraments, the funeral service, and the various benedictions. The sacramental of most frequent use in the Church is the _sign of the cross_. It is used to remind us of the Passion and Death of Our Lord and Saviour Jesus Christ on the cross. The cross is the emblem of the Christian, the "sign of the Son of Man." It is an act of faith in the principal truths of Christianity. When we say the words, "In the name," we profess our faith in the unity of God, which means that there is but one God; "of the Father and of the Son and of the Holy Ghost," are a profession of faith in the Trinity--_i.e._, that there are three divine persons in one God. The form of the cross which we trace with our right hand from our forehead to our breast, and then from the left to the right shoulder, is a profession of faith in the Incarnation of the Son of God, who became man and died on the cross for our redemption. Tertullian and other writers of the early ages of the Church tell us that before every action, before rising or retiring, before meals, at every step, "we impress on our forehead the sign of the cross." The Catholic Church of to-day, in accordance with the teachings of Christ, His apostles, and their successors of all time, teaches her children to put their trust in the merits of Jesus Christ's sufferings on the cross, and to do everything "in the name of the Father and of the Son and of the Holy Ghost."
