“Having your own church and interpretations of the same words guarantees nothing, least of all accurate theology.”
Perhaps, but IGNORING the plain meaning of a scripture in favor of one that uses one or two verses to support Purgatory, or none at all to supporting confessions to priests, all in order to conform it to a tradition that was NOT passed down from the Apostles, but ‘unfolded’ later on pretty well guarantees bad theology.
If one wants to achieve falsehood, then pretending to read scripture while forcing on it meanings from traditions that consist of men’s opinions expressed over hundreds or a thousand years is a good way to make one’s goal!
So you say, I believe that's obviously false. Apostolic succession is passing down much more than clothes and manners and habits and methods. Spiritual knowledge cannot be reduced to these or - to words on a page.

The history of the Church is that men can derive all sorts of heresy from plain reading - heretical theology argued from scripture - and continues to do so today. Orthodoxy is supported by scripture, but scripture alone fails to maintain Orthodoxy.
