Indeed. Thanks.
Actually, to me, The Canon was decided much the same way Paul exhorts the local congregation to vet prophetic/word of knowledge etc. stuff in it's midst--prayerful pondering and discernment as a group.
Thankfully, after 300+ years, the church seemed to have a pretty reasonable sense of what God had blessed as The Canon.
Yes, that's exactly the way I see it. God established the Canon through His Church. Those at councils put an official stamp on it, but it was God who did the work.
