The way each church is structured now is that each is different with unique strengths and weaknesses and working together they can compliment each other.
Now the concept presented in the OP is rather chauvinistic. Only Christians are the chosen people? Only they will save the world and defeat evil? Whatever, the specifics do not matter, because without including the other people of the world, without including humanists and atheists as equal partners, then there is no cooperation just more competition.
The single church is not a building, not a religion, it is all of humanity wanting to progress and make life decent for all.
