Neither, because the reality in which Christianity exists as a religious and social phenomenon is bigger than both the Bible and "Church Tradition" combined. Moreover, the Christian faith isn't in the process of fragmenting; it was presented to the world in a fragmentary way in the first place and many folks are apparently only just now beginning to realize this. The overall truth being that no one church polity has actually held the high ground, whether politically or philosophically, for any longer than the Lord allowed that polity to do so in the ongoing theater of the vast stretches of human history.
But, here we are, with many denominational divisions now, some old, some new, all claiming in one way or another to connect all the way back to the first apostles and, thereby, each making overt, competitive denunciations of many of the other divisions. It's sort of ironic, don't you think?
Anyway, I'd suggest you don't put all of your epistemological eggs into one basket and don't get too worked up about the use of the Trinitarian gesture. Its use, or its disuse, isn't the watershed issue that you're inflating it to be and if both you and I want to criticize the Filipino cult represented in OP article, we could both do so on other grounds than this one.
