Alright, so what makes you think I don’t understand that? (That’s mostly a rhetorical question.)
The thing that strikes me is that you bring up the question of whether SS is a “doctrine”, and the question of whether it is a “practice”; yet you never seem to bring up the “middle question” (as it were) of whether SS is true.
Good question.
Let me collect my thoughts as how this should be approached.
You see if I were claiming that SS is a Biblically true doctrine, the burden of proof would be on me to first define it and then to convincingly show from Scripture that my definition is true. To be honest although it may still be a Biblically true doctrine, I think that proving it is harder than folks think it is (either that or I am NotTooSmart); and if I were Catholic I probably would not be buying into many of the proofs I have read so far. So I won’t go there.
If I were claiming that SS is a Biblically true practice, (meaning you Catholics really should junk your magisterium and your pope being incapable of being incorrect), it would seem that we really have the same issues as a Biblically true doctrine. But that is not my motive for being here, to lecture you all on how wrong you are.
But.
Even is SS is not a doctrine or a practice that can be
proven to be Biblically true, it does
not necessarily follow that there are sources of faith other than the Bible that can be clearly identified today and that is guaranteed to be incapable of being without error today. This one sentence is key. Just because I am not smart enough to open my Bible and prove a given definition of SS as definitely Biblically true, it does not follow that your claims, or anybody elses claims for that matter are definitely true.
So, it would seem to me that in order by my practice of Sola Scriptura to be false, then in reality there must be sources of faith other than the Bible that can be clearly identified today and are clearly incapable of being in error today.
Now of course you claim that there are. And so do the Mormons for that matter.
But, according to 1 Thess 5;21, I am not to take either your say so or the Mormons say so. So then the question to me becomes “How do I carefully examine your claims and the claims of the Mormons so that I only buy into them if they are in fact true”. Because as a matter of Spiritual self-preservation, the last thing I want to do is to buy into false claims.
Since I know and have accepted the Bible as being the written, infallible, inerrant Word of God, it seems to me that those are the pages that I must turn to verify both your claims and the claims of the Mormons.
So if it can be clearly shown (so that I don’t have to make incredible leaps of logic) from the Bible that your claims and/or the claims of the Mormons are in fact true, then I have tested these claims sufficiently and I will abandon my practice of Sola Scriptura as having been shown to be false.
