“”I’ll show you what the First Vatican Council said about this:””
Glad to see you give credit to Vatican 1
Now here is the rest of it...

Now since the decree on the interpretation of holy scripture, profitably made by the council of Trent, with the intention of constraining rash speculation, has been wrongly interpreted by some, we renew that decree and declare its meaning to be as follows: that
* in matters of faith and morals,
* belonging as they do to the establishing of christian doctrine,
* that meaning of holy scripture must be held to be the true one,
* which holy mother church held and holds,
o since it is her right to judge of the true meaning and interpretation of holy scripture.
# In consequence, it is not permissible for anyone to interpret holy scripture in a sense contrary to this, or indeed against the unanimous consent of the fathers.
"Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the Word of Truth." (2 Tim. 2:15).
2. What is meant by "unanimous" consent of the fathers?
