Notes from Dr. Julian's Hymnology:
Mary Shekleton was born in 1827 and died in Dublin Sept. 28th. 1883. She was for many years an invalid, during which time she wrote several hymns, which were printed in broadsheet form. Several of these are given in "Chosen, Chastened, Crowned — Memorials of Mary Shekleton, late Secretary of the Invalids' Prayer Union, by her sister 1884", and are in common use.
1) "It passeth knowledge that dear love of Thine" (Love of Jesus, 1883) and
2) "One fervent wish, my God! It speaks the whole" (Desiring to know Jesus, 1867).
Miss Shekleton's hymns in 'Spiritual Songs' is no. 392, "It passeth knowledge that dear love of Thine", an oft sung hymn that breathes the longing of the soul to be filled with the wonderful love of Jesus, the Son of God.
