Original Trinity Hymnal, #339
O Trinity, most blessed Light,
O Unity of sov'reign might,
As now the fiery sun departs,
Shed thou thy beams within our hearts.
To thee our morning song of praise,
To thee our evening prayer we raise;
Thee may our glory evermore
In lowly reverence adore.
All praise to God the Father be,
All praise, eternal Son, to thee,
Whom with the Spirit we adore
For ever and for evermore.
