ENCYCLICAL OF POPE PIUS XII
ON THE SACRED LITURGY
151. Throughout the entire year, the Mass and the divine office center especially around the person of Jesus Christ. This arrangement is so suitably disposed that our Savior dominates the scene in the mysteries of His humiliation, of His redemption and triumph.
152. While the sacred liturgy calls to mind the mysteries of Jesus Christ, it strives to make all believers take their part in them so that the divine Head of the mystical Body may live in all the members with the fullness of His holiness. Let the souls of Christians be like altars on each one of which a different phase of the sacrifice, offered by the High priest, comes to life again, as it were: pains and tears which wipe away and expiate sin; supplication to God which pierces heaven; dedication and even immolation of oneself made promptly, generously and earnestly; and, finally, that intimate union by which we commit ourselves and all we have to God, in whom we find our rest. "The perfection of religion is to imitate whom you adore."
153. By these suitable ways and methods in which the liturgy at stated Times New Roman proposes the life of Jesus Christ for our meditation, the Church gives us examples to imitate, points out treasures of sanctity for us to make our own, since it is fitting that the mind believes what the lips sing, and that what the mind believes should be practiced in public and private life.
154. In the period of Advent, for instance, the Church arouses in us the consciousness of the sins we have had the misfortune to commit, and urges us, by restraining our desires and practicing voluntary mortification of the body, to recollect ourselves in meditation, and experience a longing desire to return to God who alone can free us by His grace from the stain of sin and from its evil consequences.
155. With the coming of the birthday of the Redeemer, she would bring us to the cave of Bethlehem and there teach that we must be born again and undergo a complete reformation; that will only happen when we are intimately and vitally united to the Word of God made man and participate in His divine nature, to which we have been elevated.
156. At the solemnity of the Epiphany, in putting before us the call of the Gentiles to the Christian faith, she wishes us daily to give thanks to the Lord for such a blessing; she wishes us to seek with lively faith the living and true God, to penetrate deeply and religiously the things of heaven, to love silence and meditation in order to perceive and grasp more easily heavenly gifts.
157. During the days of Septuagesima and Lent, our Holy Mother the Church over and over again strives to make each of us seriously consider our misery, so that we may be urged to a practical emendation of our lives, detest our sins heartily and expiate them by prayer and penance. For constant prayer and penance done for past sins obtain for us divine help, without which every work of ours is useless and unavailing.
158. In Holy Week, when the most bitter sufferings of Jesus Christ are put before us by the liturgy, the Church invites us to come to Calvary and follow in the blood-stained footsteps of the divine Redeemer, to carry the cross willingly with Him, to reproduce in our own hearts His spirit of expiation and atonement, and to die together with Him.
159. At the Paschal season, which commemorates the triumph of Christ, our souls are filled with deep interior joy: we, accordingly, should also consider that we must rise, in union with the Redeemer, from our cold and slothful life to one of greater fervor and holiness by giving ourselves completely and generously to God, and by forgetting this wretched world in order to aspire only to the things of heaven: "If you be risen with Christ, seek the things that are above . . . mind the things that are above."
160. Finally, during the time of Pentecost, the Church by her precept and practice urges us to be more docile to the action of the Holy Spirit who wishes us to be on fire with divine love so that we may daily strive to advance more in virtue and thus become holy as Christ our Lord and His Father are holy.
