This Marty Haugen song, which he says was originally an entrance hymn for Holy Thursday, is in the Lent section of CWB II because of the extra verses Haugen wrote for each week of Lent.
Happily CWB II have the chords this time.
It is up to his usual excellent standard as a singable hymn and most suitable for the solemn liturgies it addresses.
The text is here but you will need to seek out GIA’s preview to look at the Lenten verses if you don’t have CWB II, although it is also in Gather Australia 307 (& Ritual Song 541). You can buy the sheet music or view the preview at GIA.
