Advent originated as a
period during which converts prepared themselves for baptism through
instruction, prayer, fasting, and reflection, much like Lent. The length of
Advent varied from three days to six weeks—six weeks being approximately 40
days, the length of time that Jesus spent in the wilderness preparing for
His ministry.
The topic of Advent is the
Second Coming of Jesus Christ.
In the west during the
Middle Ages, Advent became a time to prepare for the Second Coming, because
in those days, many people were convinced that all the signs pointed to the
imminent return of Christ. In time, Advent spread throughout the western
Church and became fixed at its present length. Over the last fifty years,
Advent has come to anticipate the Nativity as well. For many people today,
especially retailers, Advent is just a ramp-up to Christmas. In most
churches, the Bible readings and sermons during Advent include prophecies of
the birth of Christ, but primarily concern the Second Coming, judgment, and
eternal rewards for obedient Christians.
Advent consists of the four
Sundays preceding Christmas. If 24 December is a Sunday, it is the fourth
Sunday in Advent until sundown, when the liturgical day begins, then it is
Christmas Eve.
