In my copy of the OCP Guitar Accompaniment Book:
8 Adore Te Devote (Godhead Here in Hiding)
This Latin text by Thomas Aquinas is notable for having an English translation by Gerard Manly Hopkins, the great poet. The chant is ADORE TE DEVOTE from the seventeenth century, which didn’t stop OCP copyrighting their guitar accompaniment. The sheet music is otherwise public domain and available setting myriad texts at Hymnary.
I also have a copy of the chant setting with this text in English in The Australian Hymn Book 590.
