In the Church Calendar for the year, there are 33 or 34 weeks of Ordinary Time, numbered sequentially, beginning on the Feast of the Baptism of the Lord, and ending with the feast of Christ the King - the last Sunday of Ordinary Time and of the liturgical year.
"Ordinary Time" is so called because the weeks of the Season are numbered. The Latin word ordinalis, which refers to numbers in a series, stems from the Latin word ordo, from which we get the English word order. Thus, Ordinary Time in the ordered life of the Church is the period in which we live our lives neither in feasting (as in the Christmas and Easter seasons) or in more severe penance (as in Advent and Lent), but in watchfulness and expectation of the Second Coming of Christ.During weeks of Ordinary Time we celebrate a number of special feasts, including the Baptism of the Lord, Trinity Sunday, Corpus Christi, the Sacred Heart, the Transfiguration, and Christ the King. The three year cycle of readings allows a breadth and variety of readings looking at Christian salvation. Year A features the gospel of Matthew. Mark's (and some of John's) is read in year B. Luke is the focus of Year C. Each gospel has a perspective on Jesus. words and actions, his person and mystery. Lived well, Ordinary Time can help us to be open to God's goodness, blessings and riches within, in the family, church and society. In that way, we can experience the really extraordinary in the ordinary.
