Today is the first Sunday of Advent, which is also the first Sunday of a new liturgical year for the Church. The Advent season includes the four Sundays that precede Christmas. It is a time of preparation for the coming of the Lord. In this season, we recall two central elements of our faith: the final coming of the Lord in glory and the incarnation of the Lord in the birth of Jesus. Key themes of the Advent season are watchful waiting, preparation, and justice. In today’s Gospel, we hear Jesus speak about the need for wakefulness, for watchful waiting, for the coming of the Son of Man. No one knows the precise time of the coming of the Lord in glory, so watchful waiting and vigilance are required. The passage speaks to the uselessness of looking for signs; there will be none. As a thief sneaks in during the night, so will the Lord’s coming in glory be.
The question for us as members of the Christian community, then, is how do we prepare for this? Today’s passage speaks more about the manner of waiting, rather than the details of the preparation. Jesus compares the vigilance required of Christians to the vigilance of a homeowner who knows the plans of the thief. If one knows that the thief’s action is imminent, one remains watchful. As Christians, we know that our Lord is coming even if we cannot know the precise timing. Jesus calls us to be watchful and vigilant, like the homeowner. If we become lax in our Christian living, we may be caught unprepared.
