You mean like this?:

"The Christian economy, therefore, since it is the new and definitive Covenant, will never pass away; and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ."

I think the operative word is "public".

That doesn't preclude private revelation. If the private doesn't contradict the public revelation received from Christ it might be trustworthy. If it contradicts the public it doesn't come from God.

Certainly Scripture is the solid foundation.

A lot of people fail to remember that Scripture--the Canon was decided on about 300 AD by

A GROUP OF BELIEVERS--evidently reflecting on 300 years of usage and Holy Spirit confirmation.

Which . . . is also the way Scripture in Corinthians 14:26-33 exhorts us to decide, discern about what's authentic etc.

I would also encourage a caveat that whole groups of people can still be led astray. But at least, a group of very prayerful, humble, discerning, spiritually gifted people decrease the likelihood of being led astray.

But, flawed critters that we are, it was still a group of flawed critters who decided, we believe by Holy Spirit's direction, on what the Canon consisted of--though there are still some arguments about that.
