Christian feast day: Dietrich Bonhoeffer (Anglicanism, Lutheranism)

Dietrich Bonhoeffer was a German Lutheran pastor, neo-orthodox theologian and anti-Nazi dissident who was a key founding member of the Confessing Church. His writings on Christianity's role in the secular world have become widely influential; his 1937 book The Cost of Discipleship is described as a modern classic. Apart from his theological writings, Bonhoeffer was known for his staunch resistance to the Nazi dictatorship, including vocal opposition to Nazi euthanasia program and genocidal persecution of Jews. He was arrested in April 1943 by the Gestapo and imprisoned at Tegel Prison for 1½ years. Later, he was transferred to Flossenbürg concentration camp.

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.

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.
