Yes, I do not see anything in that reference that indicates a need for the apostle Paul to be a "small h head" for the church.

Second you have changed my question into why does the church need leaders, not my question.

You said that Paul was the "small h head" of Christianity. Besides having no scriptural basis, and besides the fact that this is a ridiculous doctrine, it is also something that Paul and Peter both rejected in the clearest terms when others attempted similar things.
