„Most (Protestant) apologists either lack any formal theological study or their only exposure to Christian theology is through fundamentalist theologians (e.g. Wayne Grudem) and conservative institutions (e.g. Biola University).
As a result, many of these individuals end up with a narrow understanding of the Christian tradition which is manifested in a tendentious understanding of „biblical inerrancy”, a skepticism of evolution and contemporary science, a simplistic soteriological exclusivism, a single theory of atonement (penal substitution) and posthumous judgment (eternal conscious torment), and so on.
And the next step is that these apologists often confuse and conflate their own Protestant fundamentalist tradition with the broader Christian tradition. (For a particularly telling example, see my review of the book An Introduction to Christian Worldview.) But the Christian tradition is far broader and more nuanced than many Christian apologists realize. In short, they have yet to understand, let alone defend, that which C.S. Lewis called mere Christianity.”
