In this quote, Dietrich Bonhoeffer is expressing his belief that politics should not be the focus or responsibility of a Christian. He is suggesting that Christians must not be associated with the political world, as it is not their duty or calling. This statement might stem from Bonhoeffer's belief in the separation of church and state, and the idea that Christians must prioritize their spiritual responsibilities over worldly matters. It might likewise be analyzed as a caution versus the potential corruption and power has a hard time that can occur in politics, and the negative impact it can have on one's faith. In general, Bonhoeffer is emphasizing the value of remaining true to one's faiths and not getting knotted in the complexities of politics.
