I would suggest that you read actually what the Bereans did and why they were called noble…it is not what you think it is.
Berean Rejection of Sola Scriptura
From Steve Ray’s article:

We can see, then, that if anyone could be classified as adherents to sola scriptura it was the Thessalonian Jews. They reasoned from the Scriptures alone and concluded that Paul’s new teaching was “unbiblical.”
The Bereans, on the other hand, were not adherents of sola scriptura, for they were willing to accept Paul’s new oral teaching as the word of God (as Paul claimed his oral teaching was; see 1 Thess. 2:13). The Bereans, before accepting the oral word of God from Paul, a tradition as even Paul himself refers to it (see 2 Thess. 2:15), examined the Scriptures to see if these things were so. They were noble-minded precisely because they “received the word with all eagerness.” Were the Bereans commended primarily for searching the Scriptures? No. Their open-minded willingness to listen was the primary reason they are referred to as noble-minded—not that they searched the Scriptures. A perusal of grammars and commentaries makes it clear that they were “noble-minded” not for studying Scripture, but for treating Paul more civilly than did the Thessalonians—with an open mind and generous courtesy (see I. Howard Marshall, “The Acts of the Apostles” in the Tyndale New Testament Commentaries [Grand Rapids, Michigan: Eerdmans, 1981], 5:280).
And from the Bible:
Then from 1John 4… Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world……………6 We are from God, and whoever knows God listens to us; but whoever is not from God does not listen to us. This is how we recognize the Spirit[a] of truth and the spirit of falsehood.
