Christian feast day: Isaac Watts (Lutheran Church and Church of England)

Isaac Watts was an English Congregational minister, hymn writer, theologian, and logician. He was a prolific and popular hymn writer and is credited with some 750 hymns. His works include "When I Survey the Wondrous Cross", "Joy to the World", and "O God, Our Help in Ages Past". He is recognised as the "Godfather of English Hymnody"; many of his hymns remain in use today and have been translated into numerous languages.

The Lutheran Church has, from the time of the Reformation, continued the remembrance of saints. The theological basis for this remembrance is understood as being connected to the words of the Epistle to the Hebrews 12:1. The Apology of the Augsburg Confession states that the remembrance of the saints has three parts: thanksgiving to God, the strengthening our faith, and the imitation of the saints' holy living.

The Church of England commemorates many of the same saints as those in the General Roman Calendar, mostly on the same days, but also commemorates various notable Christians who have not been canonised by Rome, with a particular though not exclusive emphasis on those of English origin. There are differences in the calendars of other churches of the Anglican Communion.
