Dietrich Bonhoeffer publishes his essay "The Church and the Jewish Question." He calls upon Christians to defend Jews, which is a marked improvement over many Christians' attitudes towards Jews — especially in the shadow of the recent Nazi boycott of Jewish businesses.
At the same time, though, the essay is premised on Christian supersessionism — the belief that Christianity has superseded Judaism in the eyes of God. What this means is that he believed all Jews should and (eventually) would convert to Christianity. In other words, that Judaism should and would cease to exist.
