Excuse me?
Pretty simple. A religion is to be judged by the kind of society [civilization] it tends to favor and promote [by their fruit shall ye know them] - i.e. by its sociological aspects, and not by the immaterial details like "filioque', whether its clergy shaves or not, the number of daily prayers and whether the ritual headgear resembles an overturned chamberpot or not. And on these - really important - parameters Chinese "patriotic church" is indeed as good [or as bad] as the orthodox one.
