NOBODY on earth uses the Bible without "additional manmade writings and traditions". Absolutely nobody.
Don't believe me? Look carefully at the Church of Christ (Campbellite) movement. You will not find a sect more devoted to the idea that the Bible ALONE is the SOLE rule of faith. They *invented* slogans like "Where the Bible is silent, we are silent" and "No creed but Scripture".
Now look at how many factions and spin-offs there are from the CofC. "Institutional" versus "non-institutional". "Instrumental" versus "non-instrumental". And the spinoff denominations, like the "Christian Church (Disciples of Christ)" and others.
It isn't because any of them are using different Bibles. All of them read the same Bible, but they don't agree on what it means. *By definition*, all of those disagreements are manmade "traditions" that they are adding on to the text, even though they *explicitly* set out NOT to do that.
You can't get away from "tradition". "Tradition" is born every time a church leader opens the Bible and decides what it means. And if you're a "church of one" -- a completely un-Biblical place to be, but I digress -- that doesn't fix the problem. It just makes you into a "church leader".
And when that church leader sets his opinions down on paper, you have your "manmade writings".
You can't get away from "tradition" or "manmade writings," no matter how "Bible alone" you try to be. The best you can do is pick the right set of "traditions and manmade writings".
And no, John's warning about "not adding to this book" did not refer to the "Bible," which didn't exist as a single "book" when he wrote those words. They referred to the book of Revelation itself. To believe that it refers to the Bible is ... wait for it ... your very own manmade tradition.
You’re all STILL carrying on about this?! Good grief!
Do you really believe that God did not know and intend BEFOREHAND that His revelations through the prophets and the apostles would be gathered together in one book—His instructions to us during this time???
PS: that’s just a rhetorical question. No need for you to answer.
