Listen to a sermon by the Rev. Daniel Haas commemorating World Communion Sunday. World Communion Sunday is the first Sunday in October and is celebrated in all member churches of the National Council of Churches. On this day we celebrate our oneness in Christ the Prince of Peace, in the midst of the world we are also called to serve. A world evermore in need of peacemaking. This sermon was delivered Provo Community United Church of Christ on October 2nd 2011.
