Advent has a two-fold nature: It prepares us for Christmas, when we recall Christ’s first coming among us, and it is also a time when we look forward to His second coming at the end of the ages. It is a season of joyful expectation. During Advent, each Sunday’s gospel has a specific focus. The Old Testament readings, especially those taken from Isaiah,are prophecies about the Messiah and messianic times. The selections from the writings of the apostles’ present exhortations and instructions on different themes of this season.
