Chaplain Mike is doing a series on the liturgical church year at Internet Monk.  I’m not going to link each post, but this is the introduction.  The first follow-up has already been posted.  We are about to enter the season of Advent, and this would be a great time to start.  I grew up in the Baptist tradition which tends to do little with liturgy, but even the SBC churches I’ve been in light the candles of the Advent wreath each week.  If the concept of the Christian calendar is new to you, I highly recommend following Chaplain Mike’s series.
