Tonight I have witnessed what I believe to be the natural outworking of sola scriptura... I stumbled on the blog of a friend who has been lost to me for quite a while. I'm not going into the story here... suffice it to say that I think she is the victim of one of the unintended consequences of using "the Bible alone" to prove her own beliefs.
If the Bible alone is sufficient to tell us everything God wants us to know about Him and how we are to worship Him, and there is no litmus test, no external Authority, nothing against which to weigh any teaching except the Bible itself, then honestly, how can we prove or disprove anything? It ultimately comes down to my understand against yours or Luther's against the Pope's or St. Athanasios against the world.
How do I say to my friend, "You are being deceived. Yes, I can show you from Scripture... and then you can show me your Scripture and then I'll show you mine and then you'll show me yours and then we'll agree to disagree just so we can stay friends but the fact of the matter is that only one or none of us is right!"
I know I said it above but I can't get into the story here except to say that someone I know has fallen prey to a cult of Christianity and if I were to try and talk with this person about it, the discussion would sound a lot like what I wrote above.
Thankfully, and most mercifully, I have a greater weapon against deception than my own words.
I can pray.
And I will pray. Won't you join me?
