Dietrich Bonhoeffer, The Cost of Discipleship:
Christian love draws no distinction between one enemy and another, except the more bitter our enemy’s hatred, the greater his need for love. Be his enmity political or religious, he has nothing to expect from a follower of Jesus but unqualified love. In such love there is no inner discord between private person and official capacity. In both we are disciples of Christ, or we are not Christians at all. Am I asked how this love is to behave? Jesus gives us the answer: bless, do good, and pray for your enemies without reserve and without respect of persons.
