Is God Single-mindedly Open-minded?

At times I am anxious that almost every ‘brand’ of Christianity seems to have staked a claim to the Bonhoeffer legacy, and then I read: “Christmas is not a celebration for the individual but for everyone together … God’s kingdom is the whole world” (Bonhoeffer Works Vol. 9 p511).

Presumably it would have been easier for DB to say that sort of thing in a society which was in effect religiously monochrome. However, given time, maybe we Christians will find ways of sharing, for example, the Eid festivities of Muslims and they of Christmas.
