[FONT="]2 Peter 3:15 And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you;
16 As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.
1. From this passage we learn that Peter recognized Paul's epistles as Scripture, and yet not all of them, for Paul wrote many epistles (at least four to Corinth alone), all of which were not inspired. The apostles were guided by the Holy Spirit as to inspiration.
2. We also know that Peter knew of other scriptures that were inspired. This isn't necessarily a reference to the OT, but very well could be a reference to other NT epistles.
At the beginning of this same chapter he writes:
[/FONT][FONT="]2 Peter 3:1 This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance:
2 That ye may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour:[/FONT]
--This is the purpose of the epistle he writes. Keep in mind:
1. the words of the OT Prophets,
2. the commands of the apostles of the Lord.
--These two groups: the Prophets and the Apostles are our foundation. They are the authors of the Word of God. As the Prophets wrote the OT, the Apostles wrote the NT. The Holy Spirit guided them into "all truth;" "bringing into remembrance all things which Christ had spoken unto them."
[FONT="]2 Peter 1:19 We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.[/FONT]
--The RCC has a private interpretation through its Magesterium and Catechism. No one can go against the interpretation of the Catechism. What is written is written. Any thing contradictory to that is anathema. That is what is meant by a "private interpretation."
We are encouraged to study the Bible on our own.
[FONT="]2 Timothy 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.[/FONT]
But back to 1Pet.1:21. The OT was not written according to the RCC. No, it was written by holy men of God--the prophets of the OT, and the Apostles of the NT, as they were moved by the Holy Spirit. The RCC is omitted from this process.
[FONT="]2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:[/FONT]
--Their inspiration is from God, not from the RCC.
[FONT="]Jude 1:3 Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.[/FONT]
--When it says to "contend for 'The Faith' Once delivered to the saints," it is speaking of that body of faith contained in the NT. Jude was one of the last books to be written--ca. 70 A.D. The faith had been well established. It had been established in the epistles of the Apostles. Jude was a half brother of Jesus. He was born of Joseph and Mary.
He was the brother of James, also the half brother of Jesus.
[FONT="]Jude 1:1 Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:[/FONT]
[FONT="]Galatians 1:19 But other of the apostles saw I none, save James the Lord's brother.[/FONT]
Well before any council the early church had the scriptures. They were to contend for the faith contained in those scriptures. The early church knew what those scriptures were. How did they know? The apostles themselves taught them. The apostles knew which of their writings were inspired and which were not.
