The Catechism of the Catholic Church (paragraph 524) says, When the Church celebrates the liturgy of Advent each year, she makes present this ancient expectancy of the Messiah, for by sharing in the long preparation for the Savior's first coming, the faithful renew their ardent desire for his second coming. By celebrating the precursor's birth and martyrdom, the Church unites herself to his desire: "He must increase, but I must decrease."   This is a period of preparation for the celebration of the Incarnation at Christmas. As Christmas seems to arrive commercially ever earlier each year, the faithful should try to turn our hearts more toward the Lord. Mother Angelica, the foundress of EWTN, once said, Let's not let the season pass without a depth of spirituality in our hearts that lets us ponder. Ponder the mystery of how, and why, this Omnipotent God, before Whom angels tremble, would come down and live nine months in the most pure and holy woman that ever lived, and ever will live. He was confined in a womb with that Infinite Intelligence, Infinite Power, and the Power of the Holy Spirit.   First, it is a good idea to pray more, possibly including the Joyful Mysteries of the Rosary, the Franciscan Crown, and the Christmas Novena (see below), all of which call to mind the mysteries associated with the Lord coming into the world. It is also important to read Sacred Scripture, especially the Infancy Narratives of Matthew and Luke. The Catechism of the Catholic Church, chapters 2 and 3 of the Second Part on the Creed, expresses the Church's Faith in the Incarnation and Nativity of the Lord. Finally, to truly prepare, it is important to go to Confession at least once during the season, and maybe go to daily Mass and do Eucharistic Adoration when you are able.   Advent is considered the Little Lent, as it begins by recalling that Christ will come at the end of the world as Judge, a reminder of the holiness with which we should be prepared to greet the Lord. Thus, although not strictly a penitential season, the faithful should turn their hearts toward Jesus in prayer, almsgiving, and sacrifice. In the last part of Advent, we look forward with anticipation and joy to His First Coming, in Bethlehem. One way to do this is to meditate on the O Antiphons used in the Mass, each of which represents a messianic title of Christ from the Old Testament.   There are many symbols for Advent: the Advent calendar, Advent wreath with candles, the Jesse Tree, and the Crèche - with the Baby Jesus absent until Christmas Eve. Each of these can be the basis of a family tradition, especially to teach children how to prepare for Jesus' Birth.   The liturgical year has different colors for the different seasons. Redemptionis Sacramentum (No. 121) says, "The purpose of using different colors is to express the specific character of the various mysteries. The use of the diverse colors is both pedagogical and symbolic of the various liturgical feasts and seasons." Violet or purple, a symbol of suffering and penitence, is therefore the liturgical color used in Advent and in Lent.
