Thus, the liturgical year should be considered as a splendid hymn of praise offered to the heavenly Father by the Christian family through Jesus, their perpetual Mediator....
Hence, the liturgical year, devotedly fostered and accompanied by the Church, is not a cold and lifeless representation of the events of the past, or a simple and bare record of a former age. It is rather Christ Himself who is ever living in His Church. Here He continues that journey of immense mercy which He lovingly began in His mortal life, going about doing good, with the design of bringing men to know His mysteries and in a way live by them. These mysteries are ever present and active not in a vague and uncertain way as some modern writers hold, but in the way that Catholic doctrine teaches us. According to the Doctors of the Church, they are shining examples of Christian perfection, as well as sources of divine grace, due to the merit and prayers of Christ; they still influence us because each mystery brings its own special grace for our salvation. Moreover, our holy Mother the Church, while proposing for our contemplation the mysteries of our Redeemer, asks in her prayers for those gifts which would give her children the greatest possible share in the spirit of these mysteries through the merits of Christ. By means of His inspiration and help and through the cooperation of our wills we can receive from Him living vitality as branches do from the tree and members from the head; thus slowly and laboriously we can transform ourselves "unto the measure of the age of the fullness of Christ."
-Pope Pius XII, Mediator Dei, Articles 161, 165.

GENERAL INTRODUCTION

Let the Catholic who reads this work be on his guard against that coldness of faith and that want of love which have well-nigh turned into an object of indifference that admirable cycle of the Church, which heretofore was, and always ought to be, the joy of the people, the source of light to the learned, and the book of the humblest of the faithful.
Dom Gueranger, O.S.B.
The Liturgical Year
One of the chief ways that the Church teaches and reteaches the deposit of Faith is through its liturgical cycle. The calendar of the Church, which takes its point of departure from the natural seasons, the Old Law and the New, stretches out over a twelve-month period the divine things that are present in a condensed form in every single Mass. This distension of the mysteries over the course of a year allows the faithful to appropriate, gradually and solemnly, the deeper meaning of their faith. Just as the observant eye learns how to read the inner workings of nature from the changing signs of the season, so too does the pious eye learn the essence of supernature from the rhythms of the liturgical calendar. Dom Gueranger is right: the Church calendar is a book, a book filled with mystagogical signs and hints which, if read properly and attentively, disclose the full light of Christian wisdom. What is more, reading this "book" precipitates an annual renewal of, or re-initiation into, the whole of our Christian faith, from our fall into sin to our redemption in Christ, from our faltering attempts at holiness to our joyful if not anxious anticipation of contemplating God face to face.
The liturgical calendar is therefore not only something that illuminates our minds, but inflames our hearts. According to Plato's Republic the perfect city is one in which citizens experience identical pleasures and pains at the same time, as if the whole community were a single body wincing or delighting in unison. The Church calendar is the fulfillment of that philosophical ideal. From the exilic pining of Septuagesima to the austerity of Lent, from the grief of Passiontide to the jubilance of the Pasch, the Church, by staggering its feasts and observances in a particular order, enables the faithful to experience a number of holy feelings as one. Indeed, the emotional range of the traditional Roman rite is perhaps the most variegated in all of Christendom. Complex emotions, such as joy-in-penitence (Laetare and Gaudete Sundays) or penitence-in-joy (the lesser Rogation Days), are not uncommon. Hopeful sorrow, jubilant fasting, cathartic anguish: all find their home in the preconciliar Roman calendar. By ordering and harmonizing our emotions in such a way, this affective panoply serves an important purpose. As David Mills recently wrote in the New Oxford Review, "You are in training for heaven, and therefore you do not always get what you want at the moment, as you can do in revivalist Protestantism, but rather what you need for eternity-- and the restraint on your desires is part of that training for eternity" ("Emotionalism or Ritualism," 12/99).
It is because immersion in the liturgical cycle is so important that we include this section on the meaning of the seasons and the traditional customs that have helped carry them from the church into the home. And we find this endeavor most rewarding, as the old Church calendar is particularly resplendent with the kinds of signs, compasses, and emotional bookmarks so conducive to Christian sanctification. It is our hope that this section will not only deepen our love for "that admirable cycle of the Church," but will encourage the appropriation of the calendar's external observances and internal teachings.
