Dear Beamishboy,
I take your point about following the word of God, but did you ever come across a Christian who claimed to be doing anything else?
That's where our difficulty can arise. We all read the word of God, but, as this little discussion over the Petrine verses shows, we do not all read it in the same way. The problem arises when someone says not only that his or her intepretation is right, but the only right one; that person arrogates to themselves a power that not even the Pope in Rome claims, namely personal infallibility.
The Orthodox and the Catholics would say that we need someone or something to turn to when individuals differ; historically this has been the elders, as we see as far back as the Acts of the Apostles. The Church, founded by Christ, who wrote no book, is inspired by the Spirit, and it established the canon of Scripture through its reception by the faithful, and the writings of the Fathers; it also expresses the faith of the people through its ancient liturgies. Here we have not simply our own reading, but the reading of the faithful down the ages; we give, if you like, the Church invisible a vote as well as the Church visible.
That, of course, still does not, as we have seen, guarantee unity, but since the Orthodox and the Catholics receive different Councils, that is not, perhaps, altogether surprising.
Of course, in the final resort we all rely upon our conscience, and I should have expressed that a lot better; but relying solely upon our own reading exposes us to the risk that our prideful nature may mislead us.
Peace,
Anglian
