This is by Melvin Lloyd Farrell and, while not mentioned by CWB II, is one of several hymns loosely based on the original Latin text Adoro te Devote by Thomas Aquinas. It is set to the chant ADORO TE DEVOTE. It is for Eucharist or Adoration.
Mary at Godsongs has looked at this one extensively. Some of the lyrics in the version she has match the verses in CWB II, but I can only find the identical lyrics to CWB II elsewhere in (no surprise here) CWB I! I did find almost all of what is in CWB II with even more verses here. It has a refrain in CWB II (the first two lines of stanza four at Godsongs) but that is not always used.
