You mean early church fathers in Scripture, which held that to be the only substantive wholly inspired body of Truth, to which their own preaching of the word of God was subject to.
A few later so-called "fathers" may have professed this but overall they deviated from it to varying degrees, if not to the point that souls could not be saved, and the body of Christ continue.
Absolutely! When the basic tenets of the Christian faith were being defended against heretics who started immediately to challenge what was believed always, everywhere and by all, the sacred God-breathed Scriptures were recognized and held as THE standard to determining what was the divinely revealed body of truth. Paul told believers that he did not shun to declare to them all the counsel of God (Acts 20:27). Paul forewarned that grievous wolves would creep in to scatter the flock of God and "of their own selves shall men arise, speaking perverse things, to draw away disciples after them."
The example had always been that God revealed the truth to His prophets and that it was written down and preserved for all generations. Those who chose their own philosophical meanderings and boasts of superior intelligence outside of and at odds with Scripture were and will continue to be shown as INFERIOR to the Divine word as confirmed by the Holy Spirit in word and in power.
