Miroslav Volf, speaking about I Peter, says it sums up "the New Testament teaching about how a marginalized group of Christians ought to be situated in the world"
Here's an excerpt from the part where he talks about the sectarian character of the church:
Often people think in terms of sect, or church, of someone who's really close to the power or to the margins of the power.Wouldn't that make a big difference? Wouldn't that help us move away from the dominant view of the church and Christians as being against rather than being for something?
What I found interesting in 1 Peter is how it cuts across -- how it completely muddles these distinctions. I think it muddles these around the central commitment to Jesus Christ.
And so it's not that I orient myself over and against the social groups by drawing boundaries, but rather, I am oriented around the center and boundaries fall as they might, as they will.
And the difference ends up being much softer then, as I don't have to shore up the boundaries to be distinct; I can hold on to the center and it guarantees sufficiently my distinctness.
