They are to go forth in the battle-dress of poverty, taking as little with them as a traveler who knows he will get board and lodging with friends at the end of the day. This shall be an expression of their faith, not in men, but in their heavenly father who sent them and will care for them. It is this that will make their gospel credible, for they proclaim the coming Kingdom of God.
- Dietrich Bonhoeffer
