Hello,
You still haven’t answered the question: How do you know that the Bible is inspired? How do you know what books to include and which not to include? And most importantly (for the sola scriptura crowd) where is
that in the Bible?
The same way that I can say that I believe in the Trinity. It was worked out and deduced from the Bible - no, it is not spelt out there, but with just the bible, and no other “inspired” knowledge, it is possible (and, i believe, probable) that one can arrive at the conclusion that the Trinity exists.
This can be done without Roman Catholic Tradition, thus I can hold that both the concept of the Trinity and Sola Scriture are correct.
Please prove it. You made the assertion, so back it up. Imagine that the Bible is dropped off at an isolated tropical island. It is in the language of the natives, so they can read it. Show how, without any outside influence telling them how to interpret it, they come to the knowledge of the Trinity.
…once again: compliance with the scriptures. (that is, OT).
Eye witness accounts.
Things written by people who were there.
Accurate historical documents.
Lack of disagreement in the early church (that is, up to ~100AD)
It can be argued that Mark and Luke were not eye witnesses but learned the faith from the Apostles. Paul was a witness to the Resurrection on the road to Damascus, but where did he learn the rest of the faith?
There are many historical documents from that period, like Roman governmental decrees and such, and secular historian’s works. Why aren’t they then in the Bible?
Lack of disagreement?! You’re kidding right?! Most of Paul’s correspondence was to correct errant thinking in the communities he founded. One example, out of many, many, many possible examples:
“I appeal to you, brethren, by the name of our Lord Jesus Christ, that all of you agree and that there be no dissensions among you, but that you be united in the same mind and the same judgment. For it has been reported to me by Chlo’e’s people that there is quarreling among you, my brethren.” (1 Corinthians 1:10-11) - and it goes on from there.
You might need a new version?
20Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation. 21For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.
2 Peter 1:20-21
Importantly - the
prophet’s own interpretation.
The NIV is one of the worst translations I have ever seen of the Bible. For serious study in English, your best bet is the RSV:
“First of all you must understand this, that no prophecy of scripture is a matter of one’s own interpretation, because no prophecy ever came by the impulse of man, but men moved by the Holy Spirit spoke from God.”
The Latin has it: “hoc primum intellegentes quod omnis prophetia Scripturae propria interpretatione non fit; non enim voluntate humana prolata est prophetia aliquando, sed a Spiritu Sancto ducti locuti sunt a Deo homines.”
The key phrase is: propria interpretatione - this means one’s own interpretation:
proprius -a -um [one’s own , special, peculiar, characteristic; lasting, permanent]. Hence adv. proprie, [exclusively, peculiarly, characteristically; in a proper sense].
interpretatio -onis f. [explanation , interpretation, translation]. Transf., [meaning, signification].
Well, this one does not help you at all!

Yes, they are hard. And yes, the “unlearned and unstable” twist them. But so what of it? I can say that RCT has twisted what the Bible says of Mary. Can you argue against that?
Yes, it can be argued, and has - and has been refuted. The Catholic teaching on Mary is not contradictory to Scripture, unlike the common Protestant understanding of Mary which is in direct conflict with Scripture.
Read through the NT, find apostles dying, and note the lack of replacements. Additionally, if they were all to be succeeded, there should be 12 popes now, shouldn’t there?
No, but there are the Bishops, who are the direct successors of the Apostles.
