My first impression is that it is not simply a statement of a positive. ("The Lord IHS Christ is, as Paul saith, the Head of the Body so that no other man should be called the head of the Church on earth." Something like that, and even the "so that" clause seems unnecessary, strictly speaking.) The almost repetitive nature of it suggests that it is in reaction to something -- and, IF that's right, the something would be those churches in communion with the See of Rome.
Are you thinking it is nothing more than a statement of general principle?
I don't think it's a no-brainer either way in any event.
It’s clearly a matter of whose straw is being picked.
That’s ok. That was the point of the exercise.
