Adapted from The Liturgical Year
by Abbot Gueranger
We apply the name of Christmas to the 40 days which begin with the Nativity of Our Lord, December 25, and end with the Purification of the Blessed Virgin Mary, February 2. It is a period which forms a distinct portion of the Liturgical Year; as distinct, by its own special spirit, from every other, as are Advent, Lent, Easter or Pentecost. One same Mystery is celebrated and kept in view the whole 40 days. Neither the Feasts of the Saints, which so abound during this Season; nor the time of Septuagesima, with its mournful Purple, which often begins before Christmastide is over, seem able to distract our Holy Mother the Church from the immense joy of which She received the glad tidings from the Angels (Luke 2:10) on that glorious Night for which the world had been longing 4000 years. The custom of celebrating the Solemnity of Our Savior’s Nativity by a Feast or commemoration of 40 days’ duration is founded on the Holy Gospel itself; for it tells us that the Blessed Virgin Mary, after spending 40 days in the contemplation of the Divine Fruit of Her glorious Maternity, went to the Temple, there to fulfill, in most perfect humility, the ceremonies which the Law demanded of the daughters of Israel, when they became mothers.
The Feast of Mary’s Purification is, therefore, part of that of Jesus’ Birth; and the custom of keeping this holy and glorious period of 40 days as one continued Festival has every appearance of being a very ancient one, at least in the Roman Church. And firstly, with regard to Our Savior’s Birth on December 25, we have St. John Chrysostom telling us, in his Homily for this Feast, that the Western Churches had, from the very commencement of Christianity, kept it on this day. He is not satisfied with merely mentioning the tradition; he undertakes to show that it is well founded, inasmuch as the Church of Rome had every means of knowing the true day of Our Savior’s Birth; since the acts of the Enrollment, taken in Judea by command of Augustus, were kept in the public archives of Rome. The holy Doctor adduces a second argument, which he founds on the Gospel of St. Luke, and he reasons thus: we know from the sacred Scriptures that it must have been in the fast of the seventh month (Lev. 23, 24 et seq.) that the Priest Zachary had the vision in the Temple; after which Elizabeth, his wife, conceived St. John the Baptist (the ‘seventh month’ corresponded to the end of our September and beginning of our October). Hence it follows that the Blessed Virgin Mary having, as the Evangelist St. Luke relates, received the Archangel Gabriel’s visit, and conceived the Savior of the world in the sixth month of Elizabeth’s pregnancy, that is to say, in March, the Birth of Jesus must have taken place in the month of December.
But it was not till the fourth century that the Churches of the East began to keep the Feast of Our Savior’s Birth in the month of December. Up to that period they had kept it at one time on the 6th of January, thus uniting it, under the generic term of Epiphany, with the Manifestation of Our Savior to the Magi, and in them to the Gentiles; at another time, as Clement of Alexandria tells us, they kept it on the 25th of the month Pachon (May 15), or on the 25th of the month Pharmuth (April 20). St. John Chrysostom, in the Homily we have just cited, which he gave in 386, tells us that the Roman custom of celebrating the Birth of Our Savior on December 25 had then only been observed ten years in the Church of Antioch. It is probable that this change had been introduced in obedience to the wishes of the Apostolic See, wishes which received additional weight by the edict of the Emperors Theodosius and Valentinian, which appeared towards the close of the fourth century, and decreed that the Nativity and Epiphany of Our Lord should be made two distinct Festivals. The only Church that has maintained the custom of celebrating the two mysteries on January 6 is that of Armenia; owing, no doubt, to the circumstance of that country not being under the authority of the Emperors; as also because it was withdrawn at an early period from the influence of Rome by schism and heresy.
The Feast of Our Lady’s Purification, with which the 40 days of Christmas close, is in the Latin Church of very great antiquity; so ancient, indeed, as to preclude the possibility of our fixing the date of its institution. According to the unanimous opinion of Liturgists, it is the most ancient of all the Feasts of the Holy Mother of God; and as Her Purification is related in the Gospel itself, they rightly infer that its anniversary was solemnized at the very commencement of Christianity. Of course, this is only to be understood of the Roman Church; for as regards the Oriental Church, we find that this Feast was not definitely fixed to February 2 until the reign of the Emperor Justinian, in the sixth century. It is true that the Eastern Churches had previously to that time a sort of commemoration of this Mystery, but it was far from being a universal custom, and it was kept a few days after the Feast of Our Lord’s Nativity, and not on the day itself of Mary’s going up to the Temple.
But what is the characteristic of Christmas in the Latin Liturgy? It is twofold: it is joy, which the whole Church feels at the coming of the divine Word in the Flesh; and it is admiration of that glorious Virgin, Who was made the True Mother of God. There is scarcely a prayer, or a rite, in the Liturgy of this glad Season, which does not imply these two grand Mysteries: an Infant-God, and a Virgin-Mother. For example, the magnificent Anthem, Alma Redemptoris, composed by the Monk Herman Contractus, continues up to the very day of the Purification to be the termination of the Divine Office. It is by such manifestations of Her love and veneration that the Church, honoring the Son in the Mother, testifies Her holy joy during this season of the Liturgical Year, which we call Christmas.
Our readers are aware that, when Easter Sunday falls at its latest—that is, in April—the Ecclesiastical Calendar counts as many as six Sundays after the Epiphany. Christmastide (that is, the 40 days between Christmas day and the Purification) includes sometimes four out of these six Sundays; frequently only two; and sometimes only one, as in the case when Easter comes so early as to necessitate keeping Septuagesima, and even Sexagesima Sunday, in January. Still, nothing is changed, as we have already said, in the ritual observance of this joyous season, excepting only that on those two Sundays, the fore-runners of Lent, the vestments are violet, and the Gloria is omitted.
Although our Holy Mother the Church honors with special devotion the Mystery of the Divine Infancy during the whole season of Christmas; yet She is obliged to introduce into the Liturgy of this same season passages from the holy Gospels which seem premature, inasmuch as they relate to the active life of Jesus. This is owing to there being less than six months allotted by the Calendar for the celebration of the entire work of our Redemption: in other words, Christmas and Easter are so near each other, even when Easter is as late as it can be, that Mysteries must of necessity be crowded into the interval; and this entails anticipation. And yet the Liturgy never loses sight of the Divine Babe and His incomparable Mother, and never tires in Their praises, during the whole period from the Nativity to the day when Mary comes to the Temple to present Her Jesus.
