The apostate preoccupation with supremacist dissecting of (peripheral) doctrines, known as "ethnocentrism" was born at Nicaea and perpetuated by most religions including the Watchtower.
The end result is always a drawing away from the explicit and unabridged gospel.
This is exactly why WBTS followers call themselves "publishers of the Good News" whilst ignorant of the "Good News" according to Paul, Moses, Isaiah and Psalms.
As one old pyramidologist correctly observed:
"The endeavor to compel all men to think alike on all subjects, culminated in the great apostasy and the development of the great papal system, and thereby the gospel, the one faith that Paul and the other apostles set forth, was lost - buried under the mass of uninspired decrees of popes and councils. The unity of the early church, based upon the simple gospel and bound only by love, gave place to the bondage of the church of Rome ... Each new reform movement (like Protestantism) has made the failure of attempting to make a creed just large enough for its prime movers ." --WT, Sep. 1893, p. 1572
