In Catholicism, we believe that the Bishops in Communion with the Pope (as Vicar of Christ) have authority over Church doctrine. The authority comes straight from the mouth of our Savior.
Matthew 18:18 (NAB)
18 Amen, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.
So, for non-Catholics and for other Christians who stake their claim to apostolic succession yet hold that the Bible is the only authority, can anything really be bound or loosed by the apostles or their successors? What does this passage mean outside of my interpretation?
