There has been a passage from Bonhoeffer’s “Life Together” that I have been thinking about a lot lately:
…from the moment when a man meets another person he is looking for a strategic position he can assume and hold over against that person. There are strong persons and weak ones. If a man is not strong, he immediately claims the right of the weak as his own and uses it against the strong….It is the struggle of the natural man for self-justification. He finds it only in comparing himself with others, in condemning and judging others. Self-justification and judging go together, as justification by grace and serving go together. (90-91).
