Today is All Saints' Day in the western church calendar. Here is the collect for the day, as prescribed by the Book of Common Prayer:
O Almighty God, who hast knit together thine elect in one communion and fellowship, in the mystical body of thy Son Christ our Lord; Grant us grace so to follow thy blessed Saints in all virtuous and godly living, that we may come to those unspeakable joys, which thou hast prepared for them that unfeignedly love thee; through Jesus Christ our Lord. Amen.
Here are a few of the wonderful hymns typically sung today in the churches: "For All the Saints," "Jerusalem the Golden" and "Who Are These Like Stars Appearing."
