the canon of Scripture is a form of doctrine which (ONLY IF YOU ARE MAINTAINING SOLA SCRIPTURA) must be tested by Scripture.
(The nested quote is from @catholicray)
It is not
necessary to test the table of contents by scripture
if the table of contents may tested by something else. So if I correctly answer the question “what, other than scripture, may the table of contents be tested by?” then I’ll have shown that “it’s not true that the table of contents must be tested by scripture”. That question is the correct one if you want to test my statement.
But that’s a
different question than what you’ve asked. You said “what
should it be tested by”, not “what
may it be tested by”. You imply obligation–you’re implying that the table of contents
ought to be tested by something. That’s an assertion. To really be thorough I could ask you to back up your assertion that the table of contents ought to be tested by anything. Perhaps this is trivial to prove, perhaps not. But you have implied this. So… are you willing to show that the table of contents
requires testing by anything?
Now you might be getting frustrated because that’s not the whole story. You see, when I said “I don’t believe it must be tested” then I asserted belief in a
lack of something. That’s an assertion that I made. So why am I not turning the screws on my own thumbs?
But wait, there’s more. I was challenging something that @catholicray asserted–“the canon
must be tested by scripture”.
So here’s where we stand: @catholicray asserted something. I asserted the opposite. You (@Cathoholic) asserted the something again.
So what’s the next move? Is it my turn now to restate the opposite assertion again, since the number of opposite assertions is now lacking? Or should I attempt to back up my opposite assertion while letting you guys sneak by? Or should you guys do the hard work while I sit back?
I guess I’ll try my hand at answering “what, other than scripture, may the table of contents be tested by?” Here goes!
God is able to test the table of contents. God is not scripture. Therefore, it is not true that the table of contents must be tested by scripture.
Now I doubt anyone is going to be satisfied by this answer. But regardless of your feelings, there it is, without cheating. Now it’s your turn.
Regardless, here’s one for ya’. Feel free to pick this apart, but to me this sounds like a pretty good answer for “what’s the best way for us to judge the correctness of the canon”:
