If Machen Wrote a Book Today...

If Machen were living today, Jon Payne believes he would write another book. This one would be entitled Christianity & Evangelicalism.
Are Christianity and evangelicalism so radically different now that they actually constitute two different religions altogether? 
Is evangelicalism a rival to Christianity?
What are each founded upon?
Dr. Payne warns that he is not going to be highly nuanced in this sermon, as he is pleading with his congregation to hold fast to authentic Christianity. It’s a powerful message for the whole church, as we are living in a post-Christian culture. Who are we listening to? 
I recommend you do take a listen to our friend Jon, “No Payne, No Gain”:
