Bonhoeffer reminds me a little bit of Oswald Chambers in that when I first read something he wrote, I think, "What is he talking about?" And I have to meditate on it a little bit in order to decide whether I agree or not.
More of the passage (with added spacing and emphasis):
"As only Christ can speak to me in such a way that I may be saved, so others, too, can be saved only by Christ himself. This means that I must release the other person from every attempt of mine to regulate, coerce, and dominate him with my love. The other person needs to retain his independence of me; to be loved for what he is, as one for whom Christ became man, died, and rose again, for whom Christ bought forgiveness of sins and eternal life.continue/-
