Bishop Robert F. Morneau, a pastor, poet and ardent Green Bay Packers' fan, writes in the December issue of Give Us This Day: Daily Prayer for Today's Catholic, "Advent celebrates God's multiple comings into our lives." The bishop identifies Advent's three stages: 1) Jesus' historic birth in Bethlehem; 2) His daily coming in the sacramental life of the Church; 3) the Lord's final coming in glory and majesty at the end of time.
The season of Advent celebrates all three "comings" by giving voice in prayer and in song to the spiritual desire, or longing, that precedes each stage.
