Recognizing something does not give you authority over the thing recognized.
God authored the genetic structure of life. Watson and Crick helped discover and describe the structure of DNA.
But it does not logically follow that because they helped us recognize something that objectively existed before them, they therefore possess infallible authority over every subsequent question concerning genetics.
Their recognition did not create DNA, give DNA its properties, or place DNA under their authority.
Likewise, God inspired Scripture. The Church recognized, preserved, copied, transmitted, and defended those writings. Even the Catholic Catechism says that the Church “discerned” which writings belong to the canon (CCC 120). Protestants can examine the same historical evidence and apply the same kinds of criteria in discerning which writings belong to the canon.
I gladly acknowledge the Church’s role in recognizing the canon.
But “the Church helped us recognize and preserve Scripture” does not logically entail:
“Therefore specifically Rome possesses infallible authority to interpret Scripture, and you must accept Rome’s doctrines wholesale.”
Recognizing something does not give you authority over the thing recognized.
And there is another assumption buried within the argument: “the Church” is being treated as synonymous with “Rome.”
Much of the early recognition and reception of Scripture occurred throughout geographically diverse churches, not through a single authoritative ruling from Rome. Christians in Alexandria, Antioch, Jerusalem, North Africa, Asia Minor, and elsewhere were receiving, citing, comparing, and discerning these writings within their own ecclesial contexts.
So even granting that “the Church recognized the canon” does not get you to “Rome gave us the canon.”
You still have to demonstrate why the catholic activity of the early Church should be identified specifically with the later claims of Roman ecclesial authority.
I have no problem receiving the testimony of the historic Church.
What I reject is the assumption that receiving the testimony of the historic Church requires me to accept Rome’s claims of authority over that Church.
Scripture is authoritative because God authored it.
The Church’s recognition of that authority is an important historical witness to what God had already given. It is not the source of Scripture’s authority, nor does it establish Rome as an infallible interpretive authority.
