Dear Lord and Father of Mankind is a hymn text by the American Quaker poet John Greenleaf Whittier (1807-1892) that is customarily sung to either of two tunes. In the US, the tune Rest by the English organist and teacher Frederick Charles Maker (1844-1927) is more popular, while in the UK, Repton by the English composer, teacher, and music historian Sir Charles Hubert Hastings Parry (1848-1918) is prevalent.
