Writings, not direct words. I'll repeat what I said because I don't think you understand my point.
There are the direct words of God which are infallible. (Which includes direct words to Prophets and others from God.)
and then there's others teachings and writings between prophets and disciples that are fallible. (I gave the example of Pauls letters, or the book of Hebrews as an example.)
If it's not a direct quote, then the message can be misunderstood, the teaching can be misunderstood, and the concept can be 100% accurate, but the way its told/taught can have issues or errors. There's an instance even written down about Paul disagreeing with Peter and publicly corrected him because of what Peter was teaching. Where is the line drawn between "inspiration" from God and a humans teachings? Just because someone is a follower of God or they write something down, doesn't automatically mean their words are infallible. The example I gave of Peter, is a good example of that. He was teaching others something Paul considered inaccurate (requiring gentiles to be circumcised). And you could argue he had the Holy Spirit, so where is the line drawn then? Just because it's Peter? Just because it's Paul? Just because it's Matthew, or Mark, or Luke? Why do we prop people up on pedestals like they're somehow more infallible than we are?
