I do understand your concern about us relying on the decisions of the Roman Catholic church. However, I don't believe this is the case with the New Testament books. The New Testament was not established solely by edict from the Catholic church, but rather formed through consensus over the first few centuries. Only a small number of books were in dispute, and yes those were established by church councils eventually - but they were not the Pauline letters.
The vast majority of the New Testament was accepted and used throughout the church by about 200AD. The books in dispute were Hebrews, James, 2 Peter, 2 John, 3 John, Jude, and Revelation (ultimately accepted), along with 1 Clement, the Didache, Barnabas and the Shepherd of Hermas (ultimately rejected). Frankly, all of these are worth reading, including the ones that were rejected - there are good reasons they were accepted for so long. I don't mind someone disputing the precise line drawn here between which should be in or out, because it was contentious and different opinions may well be reasonably held.
But the letters of Paul were universally accepted from the early days of the church, so were not established by edict.
If any books could be said to have been imposed by edict of the Catholic church, it is the more Hebraic books that they imposed - the very books that you yourself would be least likely to dispute
@Mark C! If they hadn't defined what books were in the New Testament, we might not have Hebrews or James in the Bible!
Which goes to show that in the very early days of the established Church, they truly were genuinely trying to follow the right track. The rot set in over time, but it would be very wrong to reject the early church's opinions just because a millennium later their successors had become corrupt.
