Preparation for Christmas is an important theme for Advent, but more is involved.
Advent gives us a vision of our lives as Christians and shows us the possibilities of life. The vision of life that Advent gives us is twofold; it looks back to the first coming of Christ, and it looks to the future when Christ will come again.
In the interval between these two events we find meaning for our life as a Christian. First we celebrate Christ-become-human. We view his life and experience his presence as a human being in our history. Christ came to show us what life can and should be. He gave us true and valid principles by which we can live true and valid lives.
But Jesus knew that the human heart could not live in isolation. He formed the Church around the concept of a people held together by love. In that community we discover unlimited possibilities and meaning. Alone we can do nothing. Together we find real meaning.
When Christ left this earth, he remains with us in his Spirit, the Church, the sacraments, the Scriptures and each other. He lives in community with us and keeps his vision of life before us.
When Christ comes again, his presence will no longer be hidden behind the signs and symbols of the liturgy or the words of the Scriptures. His presence among us will be revealed in all its fullness, a presence that will never end, a presence that will perfect and complete our community. This is the “greater significance” of Advent. (10:2)
