There is no doubt, then, Bonhoeffer’s open-minded interest in Rome. While fully conscious of his Protestant roots, he explored it without iconoclasm or dogmatic prejudice. His educational background and desire to expand his own horizons led him to seek out the different and detect the good in it. He did not set out to confirm that his own denomination right in all respects; from the beginning, he was positive toward the new. The result was critical affection and affectionate criticism. It can still be sensed in the advice from his prison cell in 1944 to his friend who was staying in Rome.
