[M]odern Christians need to learn again how to be a prophetic voice in the midst of a hostile world where the Church lacks substantial cultural influence or power. Prior generations may have enjoyed a time when the modern Church was in a situation akin to the Church of the fourth or fifth centuries, the current generation finds itself in a situation that looks a lot more like what the Church experienced in the second. We are entering into (and in some ways are already in) a post-Christian world. In order to interface with this world, we do not necessarily need a new apologetic but perhaps an old one — a second -century one. Our apologetic response to our post-Christian world has much to learn form the writings of the second-century apologists.
