5th Day in the Octave of the Nativity
Commemoration of Saint Thomas of Canterbury, Bishop and Martyr
The Fifth Day within the Octave of the Nativity continues the joyful celebration that began on Christmas, focusing entirely on the mystery of Our Lord's birth. During the Octave, each day prolongs and deepens the meditation on the profound reality of the Incarnation: God made man for the salvation of humanity. While some days of the Octave commemorate saints associated closely with the mystery of Christ’s coming—such as St. Stephen, St. John the Evangelist, and the Holy Innocents—this day does not honor a particular saint, but rather continues the contemplation of Christ, truly God and truly man, lying in the humble manger of Bethlehem.
The liturgical texts and ceremonies on this day direct the faithful to the simplicity and poverty of the Christ Child, inviting adoration of His divinity hidden under the appearance of an infant. Reflection continues on the role of the Blessed Virgin Mary and St. Joseph, whose faith and obedience surrounded the Savior in His earliest moments on earth. The liturgical color is white, signifying joy, light, and purity—themes appropriate to the celebration of the Word made flesh. The octave structure allows the Church to dwell for an extended period on the central mystery of the Incarnation, which is a foundation of Christian faith and a source of hope and peace. This day, like the entire octave, is an invitation to draw near to the manger and to be renewed in gratitude and awe before the infinite condescension of God.

At that time, the shepherds were saying to one another, Let us go over to Bethlehem and see this thing that has come to pass, which the Lord has made known to us. So they went with haste, and they found Mary and Joseph, and the Babe lying in the manger. And when they had seen, they understood what had been told them concerning this Child. And all who heard marveled at the things told them by the shepherds. But Mary kept in mind all these things, pondering them in her heart. And the shepherds returned, glorifying and praising God for all that they had heard and seen, even as it was spoken to them.
