I always ask, “using the Bible and the Bible alone, where does the Bible teach the Bible alone?”
I’ve heard people reference 2 Timothy 3:16-17, 1 Corinthians 4:6, and Revelation 22:18-19.
Let’s go over those.
2 Timothy 3:16All scripture is inspired by God
Sure, all Scripture is inspired by God. But the idea that Scripture alone is inspired by God contradicts Scripture. Let’s turn to 2 Peter 1:21
2 Peter 1:21 for no prophecy ever came through human will; but rather human beings moved by the holy Spirit spoke under the influence of God.
Notice that the prophecy of Scripture, first was spoken by holy men influenced by God. Thus, holy men were inspired by the Holy Spirit.
and is useful
Does useful mean “necessary”? In fact, it doesn’t. It means profitable or beneficial. But that doesn’t say that the Scriptures have to be used.
for teaching, for refutation, for correction, and for training in righteousness,
Who is doing the teaching, refuting, correction and training? Obviously, not the Scriptures alone. But a representative of the Church.
17 so that one who belongs to God may be competent, equipped for every good work.
Notice that it is the Teaching which makes the man of God competent. We can see that it is the Teaching which is conducted by representatives of the Church which is the subject of this verse, because if you read 2 Tim, that is all that St. Paul talks about. How he is teaching St. Timothy and how St. Timothy must teach in turn and find other men to continue the Tradition. 2 Tim 2:2
1 Corinthians 4:6 I have applied these things to myself and Apollos for your benefit, brothers, so that you may learn from us not to go beyond what is written, so that none of you will be inflated with pride in favor of one person over against another.
What does he mean by going beyond what is written? Does he mean Sacred Scripture? If he does, then he isn’t talking about the New Testament. Because at the time of the writing of this verse, the only recognized Scripture was the Old Testament.
So, if he says not to go beyond what is written in the Old Testament, then we can’t believe in Jesus Christ.
Therefore, he is not talking about going beyond what is written in Sacred Scripture. He is talking about going beyond what is written in this Epistle. What does this Epistle talk about?
- Baptism, chapter 1 v. 13
- The Eucharist chapter 10 v 16
- Purgatory chapter 3 v 10-15
These are not things that Sola Scripturists believe in.
Revelation 22:18 I warn everyone who hears the prophetic words in this book: if anyone adds to them, God will add to him the plagues described in this book, 19 and if anyone takes away from the words in this prophetic book, God will take away his share in the tree of life and in the holy city described in this book.
Again, as the Bible had not yet been compiled, the book in reference above, is the book of Revelation.
I hope that helps.
