Time After Epiphany: Octave Week of Prayer for Christian Unity, Jan 18-25th
Epiphanytide is completed, but the Time-after— Epiphany keeps us within the Christmas feastspan of 40 days, as Dom Prosper Guéranger reminds us:
We apply the name of Christmas to the forty days which begin with the NATVITY of OUR LORD, December 25th, and end with the PURIFICATION of the BLESSED VIRGIN, February 2nd. 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 during the whole forty 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 good tidings from the Angels on that glorious Night…..The custom of celebrating the Solemnity of Our Savior’s Nativity by a feast or commemoration of forty days’ duration is founded on the Holy Gospel itself; for it tells us that the Blessed Virgin Mary, after spending forty 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 Liturgical Year, Christmas-Book I
The yearly Octave Week of Prayer for Christian Unity always falls between January 18th-25th, traditionally important feasts of the Apostles Peter and Paul (January 18th was formerly the Feast of St. Peter’s Chair-at-Rome). These words of Cardinal Newman, himself a convert from Anglicanism, set the tone for our prayer.
