1 Rejoice, O pure in heart!
Rejoice, give thanks, and sing!
Your festal banner wave on high,
the cross of Christ your King.
Rejoice, rejoice, rejoice, give thanks, and sing!
2 Yes, on through life's long path,
still chanting as you go;
from youth to age, by night and day,
in gladness and in woe. [Refrain]
3 At last the march shall end;
the wearied ones shall rest;
the pilgrims find their home at last,
Jerusalem the blest. [Refrain]
4 Praise God, who reigns on high,
the Lord whom we adore:
the Father, Son, and Holy Ghost,
one God forevermore. [Refrain]
In this text the imagery of a liturgical procession becomes a marching metaphor for the journey of life. The call to "rejoice, give thanks and sing" (st. 1) is extended to all people, "bright youth and snow-crowned age, both men and women" (st. 2), and on all occasions, "by night and day, in gladness and in woe" (st. 3). Life's pilgrimage has a specific goal, to be at rest in the new Jerusalem (st. 4) where all God's creatures will join in a great doxology (st. 5). The "rejoice" theme in the refrain is borrowed from Philippians 4:4.
