Today is the fourth Sunday of Advent and it is the last one of course before Christmas. Advent is a season of preparation for the birth of Jesus and not Christmas itself. While the secular world conflates the two (Advent and Christmas), the distinction is kept within the Christian church. Advent is a time of preparation for the birth so spiritual readings and vestments will reflect it. Unlike Lent which has strict observances that include fasts, Advent has no such strict requirement.
Yet it is a time for reflection as one awaits the approach of Christmas Day. In more olden times, there were fasts (it is still practiced in Eastern and Russian Orthodox where meat and dairy is prohibited for a specific period leading up to Christmas Day) but it is no longer a requirement in most Western churches. However there is a trend emerging that encourages the faithful to perhaps give up something during Advent or perform a service that benefits others (like volunteering to help feed homeless people). Music during this period also is designed to do this as well.
Happy Sunday everyone!
