Singular verse or not, it is irrelevant when it is misinterpreted. You talk about building a big old bridge off of an willow twig . . . it is a stretch to build a whole religion and AUTHORITY (that's really the key) on a single verse which has many meanings OTHER than the one your Church claims.
“Singular verse or not, it is irrelevant when it is misinterpreted.”
So what you are saying is that sola scriptura means nothing. Interpretation of scripture is crucial to proper understanding of it.
“which has many meanings OTHER than the one your Church claims.”
Which returns us to the question of authority. Who has the authority to interpret scripture?
What or who determines what is and is not misinterpreted? In the absence of any teaching authority do we simply have to take your word for it?
