Then why do you trust them to get your NT canon right?
Maybe Luther was right when he wanted to get rid of James. How do you know?
The church leaders from the early days had strict criteria by which they examined documents that were alleged to be Scripture. Authorship, alignment with what was known to be Scripture, etc. As today, men differ in their interpretations of a document, some being submissive to the Lord at times and not others. It’s easy to see why someone would have trouble with James - or Hebrews or Revelation. I do not set myself - or Luther or any pope - to tell me what the cannon is.
I research the process and arguments and have to examine my attitude towards God each time I wonder about what is in the cannon. I am sure of this - there’s nothing left out of the cannon. I have confidence that the men who were closest to the Apostles were in a better place - in time and relationship - to make the decisions about this.
How do you know the pope is always correct when he speaks “ex cathedra” (from the chair)? What gives him such purity and knowledge, etc. for only those occasions? Is the chair magic?
