I don't know how this is relevant to the point I was making in the article, but I see the Jewish countercultural view in 1 Peter 2:4-5, 9. The living stone is "rejected by humans but chosen by God and precious to him." and Christian believers are supposed to be a "holy priesthood," "a chosen people, a royal priesthood, a holy nation, God’s special possession." That indicates that this priesthood will stand apart from profane society.
This analogy comes from Isaiah, which casts Israel as a "suffering servant." That's the heart of a countercultural perspective: the underclass suffers as the dominated minority, while a spiritually impure culture corrupts the masses.
