For Catholics, the new Liturgical Year commences with the first Sunday of Advent. In this new liturgical year, the Church not only wishes to indicate the beginning of a period, but the beginning of a renewed commitment to the faith by all those who follow Christ, the Lord. This time of prayer and path of penance that is so powerful, rich and intense, endeavors to give us a renewed impetus to truly welcome the message of the One who was incarnated for us. In fact, the entire Liturgy of the Advent season, will spur us to an awakening in our Christian life and will put us in a ‘vigilant’ disposition, to wait for Our Lord Jesus who is coming:
‘Awaken! Remember that God comes! Not yesterday, not tomorrow, but today, now! The one true God, "the God of Abraham, Isaac and Jacob", is not a God who is there in Heaven, unconcerned with us and our history, but he is the-God-who-comes.’
The Season of Advent is therefore a season of vigilant waiting, that prepares us to welcome the mystery of the Word Incarnate, who will give the ‘Light’ to the womb of the Virgin Mary, but essentially this time prepares us not only to welcome this great event but to incarnate it in our lives. We could say that the true light enters the world through the immaculate womb of Mary but it does not stay there. On the contrary, this light flows out into our dark, obscure, sinful lives to illuminate them, so that we can become the light that illuminates the world. For this reason, let us live this time of waiting not only to celebrate a historical memory but to repeat this memory in our lives and in the service of others. To wait for the Lord who comes, means to wait and to watch so that the Word of Love enters inside us and focuses us every day of our lives.
As Blessed John Henry Newman reminded us in a homily for the Advent Season: “Advent is a time of waiting, it is a time of joy because the coming of Christ is not only a gift of grace and salvation but it is also a time of commitment because it motivates us to live the present as a time of responsibility and vigilance. This ‘vigilance’ means the necessity, the urgency of an industrious, living ‘wait’. To make all this happen, then we need to wake up, as we are warned by the apostle to the Gentiles, in today's reading to the Romans: ‘Besides this you know what hour it is, how it is full time now for you to wake from sleep. For salvation is nearer to us now than when we first believed” (Rm 13:11).
We must start our journey to ascend to the mountain of the Lord, to be illuminated by His Words of peace and to allow Him to indicate the path to tread (cf. Is 2:1-5).
Moreover, we must change our conduct abandoning the works of darkness and put on the ‘armor of light’ and so seek only to do God’s work and to abandon the deeds of the flesh (cf. Rm 13:12-14). Jesus, through the story in the parable, outlines the Christian life style that must not be distracted and indifferent but must be vigilant and recognize even the smallest sign of the Lord’s coming because we don’t know the hour in which He will arrive (cf. Mt 24:39-44)
The First Sunday of Advent marks the new Liturgical Year, and the Church shifts into a new Lectionary Cycle for Sundays, with 2021-22 from Year C, the Gospel of St. Luke. In the Sunday Gospel (Luke 21:25-28, 34-36) Jesus invites us to recognize the signs of the last days. This is a reminder that Advent is not just looking back at the first coming of Christ at Christmas, but our personal preparation for His Second Coming: "Be vigilant at all times and pray that you have the strength to escape the tribulations that are imminent and to stand before the Son of Man."
