Dietrich Bonhoeffer “was thoroughly disillusioned  by the cowardice of his fellow clergy. Now he had a decision to make. To do nothing against Hitler was a sin, he had reasoned. But to kill was also a sin. How could a pacifist, a man of God, justify what he was about to do? The answer was one that had first been articulated by Martin Luther, the founder of the church Bonhoeffer had loved. Sometimes, Luther said a true believer must ‘sin and sin boldly.’ Bonhoeffer would break the Commandments he vowed to uphold and renounce his cherished philosophy of nonviolence. He would lie, cheat, and plot murder. And he would do it by using the church as his camouflage.”
