It doesn’t get any better than this:

Here then the Christian faith stakes out its claim in the widest possible terms. It is no new fangled or minority cult, pandering to the special interests of a small pocket of humanity. Its truth is not one truth among others, nor its Lord a recent arrival in the world of many competing gods. On the contrary, Colossians lays a Christian claim on the whole of life, the whole of humanity, the whole of history and the whole of the universe, all in the name of Christ, the secret of all things. (John Barclay, Colossians and Philemon 92-93)
