One church?

The notion of one church in one world, still held by East and West even after their separation in 1054, gave way to a variety of denominational commitments, depending for authority upon leading theologians and the support of their political princes. Protestants still appealed to the tradition, but many viewed the tradition with a strong sense of suspicion.—Why Church History Matters, page 51

And that's where we are today: Tradition is still important, but it is redefined as choosing your favorite theologian/denomination, calling it biblical, and then calling the rest tradition and throwing it away. In other words, tradition is anything that doesn't fit my preconceived ideas of what the Bible says! OK, I'm being a bit cynical here, but I don't think I'm too far off, sadly.
