I have learned from being on this forum that Catholics understand that we know what the New Testament books are because it was decreed by a council (or 2 councils if that is possible to decree the same thing twice). I have always understood that the NT Scripture was Scripture because it met the qualifications of being written by an Apostle or by a close contact of an Apostle, and it was claimed to be inspired by the Holy Spirit and used by Christians throughout from the earliest times.
This doesn’t mean that the Holy Spirit would not be working in those creating a canon list in the late 4th century. But the same Holy Spirit that inspired the 4th century Christians was at work in the 1st century inspiring the texts and guiding the Christians to recognize and use Scripture.
1 Timothy 5:18
For Scripture says, “Do not muzzle an ox while it is treading out the grain,”[a] and “The worker deserves his wages.”****
a.1 Timothy 5:18 Deut. 25:4
b.1 Timothy 5:18
Luke 10:7
2 Peter 3:
15 Bear in mind that our Lord’s patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him. 16 He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort,
as they do the other Scriptures, to their own destruction.
And later (90AD?) Clement of Rome (or the church in Rome) wrote to the Corinthians a letter citing NT Books and referring to Paul’s 1st letter to the Corinthians as inspired by the Holy Spirit: “Take up
the epistle of the blessed Apostle Paul. What did he write to you at the time when the gospel first began to be preached? **Truly, under the inspiration of the Spirit, he wrote to you **concerning himself, and Cephas, and Apollos, because even then parties had been formed among you.” - Chapter 47

This same Holy Spirit guided the Christians of the first few centuries to recognize and use the teachings of the Scriptures. This chart shows a summary of the number of times Scripture was cited by certain early theologians:

Of course the Holy Spirit could also guide the 4th century Christians who gathered at a council to discern and use Scripture. And again, at the time of the reformation, Luther (and others) were critical of certain NT books. After careful study (and of course guidance by the Holy Spirit), the same 27 books of the NT are used by all churches that came out of the Protestant Reformation. I wouldn’t say that the councils had no importance in determining the New Testament, but the Holy Spirit also helped Christians to determine Scripture before the councils and much later guided the churches that do not recognize the councils as authoritative as well.
So IOWs, the Catholic Church got it right, but it wasn’t necessarily binding? Is there any such thing as binding?
