I have also read Unprotected Texts: The Bible’s Surprising Contradictions About Sex and Desire by Jennifer Wright Knust, which basically says there isn’t one biblical view of sex but there are many. The difference between Knust and Coogan is that Knust seems postmodern (conflating her own desires with interpreting the Bible), while Coogan is modern (makes a sharp distinction between his view of sexuality and biblical views of sexuality).

I am familiar with the usual verses thrown in support of “no sex before marriage”, but I find them unconvincing, dubious or debatable in asserting such thesis. I know that theology does not have to rely upon specific verses, but I find a contradiction between doing Sola Scriptura theology and asserting a view which is absent from the Bible.

Catholic theologians could play the “Tradition/Magisterium says so” card, but evangelicals cannot do so.
