Season of Chrimastide - as described in The New Marian Missal

During the season of Advent we longed for the coming of Christ. In Christmastide we experience the joy of His coming
into the world. The Church is full of the mystery of the Incarnation of Christ. Jesus as God, begotten of the substance
of the Father before all the ages and born of the substance of His Mother in the world, is given to us. "And His Name
shall be called the Angel of Great Counsel."

By the union of our souls with Jesus born to human life, we are born to the divine life. "As many as received Him
to them He gave power to beomce Sons of God." (St. John)

In the birth of Jesus we learn to know God as His Father: "My Father has entrusted everything into My hands; none
knows the Son truly except the Father, and none knows the Father truly except the Son, and those to whom it is the Son's
good pleasure to reveal Him." (St. Matthew)

During Christmastide, the liturgy shows us the Messias as the Son of God, clothed with humanity, glorified by the
humble, suprised shepherd and adored by the Magi from the East. Let us fall down before the Child and bless God,
for the birth of Jesus is the beginning of our Redemption through grace to the supernatural life

Christmas is the only day of the year which keeps the old custom of celebrating its feast at midnight. It was at this
hour that Mary in her spotless virginity gave to the world its Savior. In the midst of darkness, the Light was born.
Therefore the Churchcelebrates Christmas on December 25, the time of the year when the days begin to lengthen.
The custom of having three Masses originated in Jerusalem. A Mass was said in Bethehem at a very early hour in the morning. Later
a second Mass was celebrated in the Church of the Resurrection in Jerusalem. About midday a third Mass was celebrated.
Each of the three Masses has its identifying characteristic. The Midnight Mass celebrates particulrly the birth of Jesus,
the Mass at dawn commemorates the adoration of the shepherds,the daytime Mass celebrates the ternal generation of
the Word and the dignity of the Son of God.

Whereas Advent is the season of "absence of Jesus," Christmastide is a season of great joy in our possession of the Savior.
Eight days after Chrstmas the Church celebrates the Circumcision of Jesus. On January 6, she commemorates the
adoraion of Jesus by the Magi (Epiphany), with which Octave the Chrismastide closes.
