There is a specifically Christmas variant text to "Joyful, joyful", but it doesn't contain any form of the line in question:

Joyful, joyful, we adore You,
God of glory, Lord of light;
Angels lifting praise before You
Sing thro'out this holy night.
In a manger lies a Baby--
Child of Mary, Song of God.
Voices joined in joyful chorus
Praise You for Your gift of love.

All Your works declare Your glory;
All creation joins to sing.
Praise resounds as earth rejoices
In the birth of Christ, the King.
Shepherds kneel before the infant.
Trumpets sound and anthems raise
As with joy our hearts are lifted
Joined in wonder, love, and praise.
