The White Horse Inn: Know What You Believe & Why You Believe It
It's the current broadcast called
Broken Covenant. I hope they publish the transcript at some point.
The interview pretty much traces why I've become convinced that Confessions mean a great deal. We repeatedly experience the tension here from those that criticize us when they've signed up on a board of people that announce it's a voluntary association of Confessional Christians. I can only imagine the temptations to compromise when it seems like short term goals are served.
I encourage you to listen to the interview. Parker Williamson called Machen a prophet. I really think he was just already aware of where compromise leads.
