If sola scriptura is true, then it MUST be taught in scripture.
Sola scriptura is not taught in scripture.
Therefore, sola scriptura is not true.
Arthur,
That is a (sadly common) false argument you just put forth.
I’m surprised that this wasn’t covered in your seminary courses.
I will Help.

REPLY: We are offered an argument of the following form:
(1) Sola Scriptura = All true propositions are stated in Holy Scripture.
(2) Sola Scriptura is not stated in Holy Scripture.
(3) Therefore, Sola Scriptura is not a true proposition.
But in fact, the argument should be of the form:
(1) Sola Scriptura = All truths necessary to salvation are stated in Holy Scripture.
(2) Sola Scriptura is not stated in Holy Scripture.
(3) Therefore, Sola Scriptura is not a truth necessary to salvation.

Do a word search on "write".
You'll get the idea.
If the Bible is not the final authority to appeal to then you have to allow the Mormon the Book of Mormon, Doctrines and Covenants, and the Pearl of Great Price. You'd have to allow the Muslim the Koran.
