Well…I’m not sure about the Bible belonging to everyone. Yes, the message of the Bible is for the whole world, but the Bible itself, that is more problematic.
Who wrote the Bible? It was members of the congregation of God, members of God’s people, who wrote scripture. Scripture began with Moses, and he was one of God’s people. Moses wrote as one of God’s people, to the rest of God’s people. Paul, Peter, John, etc, were also all part of God’s congregation, and they were writing to and for God’s congregation. They were not writing to those who were not of the congregation; they were not writing to outsiders.
Therefore, Scripture belongs to the congregation of God, the church, not to anyone else outside of it. Scripture belongs to God’s people collectively, not individually.
You can see how this is true historically.
It is evident that scripture has always existed within a context. Now,we are are always told that individual verses of the Bible should not be taken out of context, that the surrounding verses influence what a particular verse means, but the same is true of the Bible itself. It has a context, and the Bible cannot be removed from that context if it is to be understood properly.
Peter says this when he declares in regard to the letters of Paul: “…in which are some things hard to understand, which the untaught and the unstable distort, as they do the rest of the scriptures, to their own destruction.”
That’s quite a statement. Non-Christians are evidently among the untaught, so unless you are already a Christian, the probablility of misunderstanding scripture is extremely high, and the consequences are your destruction. The Bible belongs to, and is understood within the context of those who are already taught.
Of course, Jesus makes it clear that the message of scripture, the Good News, is for everybody. He gave the commission to to his disciples to spread the Good News to all nations, Mt 28:19-20.
