Bonhoeffer....the theologian Thoreau?
For Bonhoeffer, at least from that which i have read of him (being Discipleship) he feels that the true Christian is essentially a confessing believer who has totally immersed his life in the secular world, becoming a secular Christian. Bonhoeffer in an interesting view, especially considering his involvement in a plot on Hitler's life and writing on ethics at the same time, rejects the objective unalterable moral standards of the Bible by proclaiming a situational ethics -- that right and wrong are determined solely by the "loving obligations of the moment."
When i read this something felt familiar, and i realized that the source of this resonance comes from Thoreau's essay Civil Disobedience in which he claims that we should be men first, and subjects afterward for it is not desirable to cultivate a respect for the law, so much as for the right. To boil it down, he holds that as a human "the only obligation which I have a right to assume, is to do at any time what I think right."
Perhaps there is some sort of citizenry which comes as a believer, though we do not always have the power or ability or conscience to follow what the body of believers decides. Our duty as a follower of christ is not always evident, and thus if you do not know for sure with God's will, and you have asked but cannot feel anything affirmative, then all we can do is throw ourselves out into the void, making the best possible choice according to the 'loving obligations' we feel directing, asking for forgiveness all the way.
The instigation of "at any time" is of the utmost importance, for in retrospect many decisions are straightforward while in reality...Life is simply not clear cut.
