The Missio Dei Breviary is a simple, accessible book of morning and evening prayers. It reflects a commitment to a missional, incarnational way of life with a counter-cultural vibe. The Missio Dei Breviary draws primarily from the Anabaptist tradition, but is also inspired by Benedictine, Franciscan, and Eastern Orthodox spiritualities. It offers a 28-day repeating cycle of morning and evening prayers that draw from all four gospels.
Mark Van Steenwyk is a Mennonite pastor and a founding member of Missio Dei (an Anabaptist intentional community anchored on the West Bank of Minneapolis that pursues Jesus' way of simplicity, prayer, hospitality, and peace) and general editor of the Jesus Manifesto (a webzine that explores the way of Jesus in the shadow of the Empire).
He is a writer, speaker, and grassroots educator, which means that he tries to mess with people's thinking, but he usually does this outside of an institutional setting (though he does some adjunct work with Bethel University).
