This is a wedding hymn written by Dorothy Frances Gurney for her sister’s wedding that wound up in hundreds of hymnals.
CWB set it to HIGHWOOD by Richard Runciman Terry.
Hymnary has more blurb than usual about this song.
The text has been altered by the editors with modernisation of language and some garbling of sense in the last two lines. The CWB text is below.
I got chords from TIS for a backing:
1 O perfect Love, all human thought transcending,
lowly we kneel in prayer before your throne,
that theirs may be the love which knows no ending,
whom you for evermore now join in one.2 O perfect Life, be you their full assurance
of tender charity and steadfast faith,
of patient hope and quiet, brave endurance,
with childlike trust that fears not pain or death.3 Grant them the joy which brightens earthly sorrow;
grant them the peace which calms all earthly strife;
and to life’s day the glorious unknown morrow
that draws upon eternal love and life.
