...What's interesting is that Ignatius of Antioch, in 110AD, doesn't seem to miss this kind of logic. He doesn't use the language of birth pangs, to my remembrance, he talks about becoming the "wheat" of God, that he will offer himself up and he says that he's only begun to be a disciple and that he will only fully be a disciple when he is conformed to Christ crucified. The trajectory of Ignatius' life was to be fully conformed to Christ crucified. You can see this logic work itself out in many corners of the early church, that the call to full discipleship is the call to give themselves like the Master. Whether or not they're thinking about say this book of Daniel and these other second temple texts that weren't necessarily canonical, they were living it. That is, that they were looking to continue to birth this new world to come, which is why you could see this in the rise of the cult of the martyrs, that their deaths would be called their birth day. And it's their birth into that world! "
