Sunday, October 30, 2016 is Reformation Sunday. Reformation Day is October 31.
On this day we celebrate the heart of our faith: the gospel of Christ—the good news—that makes us free! Though we give thanks for the events of the sixteenth-century Reformation that brought renewal to the church of that time, we pray that the Holy Spirit would continue to unite the church today in its proclamation and witness to the world. In the waters of baptism we are made one body; we pray for the day that all Christians will also be one at the Lord's table.
