But it is found in Scriptures, in the Gospel of John, from our Lord's own Holy lips. What is not in Scripture is the teaching that Scripture is the highest authority.
Wrong. What is not found in Scripture is the novel and unScriptural premise of ensured perpetual magisterial infallibility, and John 16 does not teach it despite egregious ecclesiastical extrapolation, nor was it ever needed or possessed in that sense in Scripture, though judicial authority is.
But what is manifest is that of Scripture being the highest authority, to which even the veracity of apostolic preaching was subject to testing by. (ACts 17:11)
First, writing is God's chosen means of reliable preservation of authoritative Truth:
- And the Lord said unto Moses, Write this for a memorial in a book.. (Exodus 17:14)
- And the Lord said unto Moses, Write thou these words: for after the tenor of these words I have made a covenant with thee and with Israel. (Exodus 34:27)
- And he wrote on the tables, according to the first writing.. (Deuteronomy 10:4)
- And it shall be, when he sitteth upon the throne of his kingdom, that he shall write him a copy of this law in a book out of that which is before the priests the Levites: (Deuteronomy 17:18)
- And thou shalt write upon them all the words of this law,..(Deuteronomy 27:3)
- And it came to pass, when Moses had made an end of writing the words of this law in a book, until they were finished, (Deuteronomy 31:24)
- Now go, write it before them in a table, and note it in a book, that it may be for the time to come for ever and ever: (Isaiah 30:8; cf. Job 19:23)
- But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name. (John 20:31)
- And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. (Revelation 20:12)
- And whosoever was not found written in the book of life was cast into the lake of fire. (Revelation 20:15)
And thus it was not because of faithful oral transmission being and effectually preserving the word among people, but it was in the absence of this that the king of Israel ripped his clothes in repentance over upon the hearing of the written word, this being the standard for obedience and testing Truth claims, upon which the NT church established its claims.
And Shaphan the scribe shewed the king, saying, Hilkiah the priest hath delivered me a book. And Shaphan read it before the king. And it came to pass, when the king had heard the words of the book of the law, that he rent his clothes. (2 Kings 22:10-11)
Go ye, enquire of the Lord for me, and for the people, and for all Judah, concerning the words of this book that is found: for great is the wrath of the Lord that is kindled against us, because our fathers have not hearkened unto the words of this book, to do according unto all that which is written concerning us. (2 Kings 22:13)
For as is
abundantly evidenced, the word of God/the Lord was normally written, even if sometimes first being spoken, and that as written, Scripture became the transcendent supreme standard for obedience and testing and establishing truth claims as the wholly Divinely inspired and assured, Word of God.
