The Sundays of the major seasons of
the year are distinguished by their relationship to the Solemnities of Christmas
and Easter. The rhythm of these
liturgical seasons reflects the rhythm of life — with its celebrations and its
seasons of growth. Ordinary Time, meaning ordered or numbered time, is
celebrated in two segments. 1) From the Monday following the Baptism of Our Lord to Ash Wednesday.
2) From Pentecost Monday to the First Sunday of Advent. This
makes it the longest season of the Liturgical Year. The Church counts
thirty-three or thirty-four Sundays of Ordinary Time (60% of
the Church's calendar), inviting us to meditate upon the whole mystery of
Christ – his life, miracles and teachings – in the light of his Resurrection.
The vestments for Ordinary Time are usually green, the color of hope and
growth.
The
Feast of the Baptism of the Lord brings the Christmas season to a close. Baptism
forgives all sin and incorporates one in the life of the Trinity. Believers
are given a share in the divine nature. In addition, baptism makes one a
member of the body of Christ and of the visible manifestation of that body,
the Church, and provides a share in the mission of Jesus. Water is
the main symbolic element that conveys the sacrament of baptism, along with
the words, "I baptize you in the name of the Father, and of the Son,
and of the Holy Spirit." That triple plunging or immersing in the water
symbolizes dying to the old self. Coming up out of the water corresponds to
being born as a new person in Christ (Catechism of the Catholic Church p.
1239-40).
