Understanding the Scripture through a better understanding of the context

I enjoyed reading this post from "Between Two Worlds" blog site earlier this morning.
When you start to understand the point D.A. Carson is making about context it helps to build healthy biblical categories as you read the Bible.

The following was in an email from D.A. Carson to Mark Driscoll, as cited in Driscoll's chapter ("The Church and the Supremacy of Christ in a Postmodern World") in the forthcoming book, The Supremacy of Christ in a Postmodern World:

Paul refuses to circumcise Titus, even when it was demanded by many in the Jerusalem crowd, not because it didn’t matter to them, but because it mattered so much that if he acquiesced, he would have been giving the impression that faith in Jesus is not enough for salvation: one has to become a Jew first, before one can become a Christian. That would jeopardize the exclusive sufficiency of Jesus.

To create a contemporary analogy: If I’m called to preach the gospel among a lot of people who are cultural teetotallers, I’ll give up alcohol for the sake of the gospel. But if they start saying, “You cannot be a Christian and drink alcohol,” I’ll reply, “Pass the port” or “I’ll think I’ll have a glass of Beaujolais with my meal.” Paul is flexible and therefore prepared to circumcise Timothy when the exclusive sufficiency of Christ is not at stake and when a little cultural accommodation will advance the gospel; he is rigidly inflexible and therefore refuses to circumcise Titus when people are saying that Gentiles must be circumcised and become Jews to accept the Jewish Messiah.
