Basically, the two churches are bound together much more intimately than most Christians think. Should the Roman Church fall, the Protestant churches won't rush in and fill the void. They will fall soon afterward. The Catholic express and the Protestant choo-choo are rolling on the same rails, and if the bridge washes out, both are destined for the gulch. In the long run, Protestants stand to lose as much from the mortality of Jesus as do the Catholics. We can't expect any support from them. Except maybe the Unitarians. They'll embrace any heresy, I understand.
