Bonhoeffer's 4 mandates

“The commandment of God revealed in Jesus Christ embraces in its unity all of human life. Its claim on human beings and the world through the reconciling love of God is all-encompassing. This commandment encounters us concretely in four different forms that find their unity only in the commandment itself, namely, in the church, marriage and family, culture, and government.” —Bonhoeffer, Ethics, page 388
