The Society of St. Andrew, the national gleaning ministry, has two Advent programs that may be of interest to you and your church.
The free Advent devotional booklet, "Passing the Peace," will guide you toward Christmas with daily readings to aid your preparation for Christmas Eve. The booklet also provides a way to contribute to feeding the hungry in America. All details are at http://www.endhunger.org/advent.htm.
The Alternative Gift Christmas Card program is a way to send Christmas greetings to friends and family, to let them know that you have fed hungry Americans in their name, and to share God's love in a real way with strangers in need.
