I wish there was an "other" box because I can't honestly vote in any of the above categories. Though I would tend towards the second it isn't a complete answer.
There are three reasons, imho, why we've seen a resurgence of Reformed theology:
1. Publishers are behind it because it sells books and packs conferences. Don't discount this as the primary reason, imho, we have seen the volume turned up. As recent surveys have shown it isn't a resurgence as much as it is increased volume. Honestly this is a major issue. The reality that they have put younger and more dramatic faces behind most of Reformed leadership is also part of this. In general surveys of recent seminary grads and pastoral leadership in evangelical churches there isn't as much a resurgence as we have been led to believe. This is a publisher pushed conversation.
2. It is a discipline (notice here not
the but
a) which brings together strict biblicism and (fairly) conservative theology. When the SBC was beginning their resurgence they had to tie in with many Reformed folk because they were the only ones who held the Bible in as high a standard as the leaders of the resurgence. It was an uneasy, but necessary alliance. It also gave a pretty big platform to their rising stars. The Reformed school constantly pivots to a robust view of Scripture and can identify, exegete, and apply their selected Scriptures to provide basis for their view. How many Reformed folk have you been in conversation with? Just curious. Because of the many that I have encountered, when you push the buttons and go outside their selected verses they begin to lose a foothold. Just being honest. To their credit, the Reformed leadership has done an excellent job informing their followers of the basics of their beliefs. It is a pretty simple system too.*
3. Because it is cyclical. Look back over the past 500 years since the start of the Reformation. Jean Calvin wasn't the first to posit the Reformed point of view. He simply formulated it in the final edition of his magnum opus
Institutes of the Christian Religion. Did a great job too. The Church, since then, has gone through a ton of change but has seen a regular pattern of rising and falling of Reformed influence. We just happen to be in a time where it is rising.
You know a lot of this conversation is based on poorly defined concepts too. Too many Reformed folk only know the talking points and have never gotten into the base literature. Seriously, how many of them have actually read the
Institutes?
I'm not Reformed but respect those who are...if they understand why they believe and are not hopelessly dogmatic. There is a lot more to be said but I'll end it there.
* Fun point here, notice how flexible the system is too. Most historic Reformed theologians are historical premillenialists but most modern are dispensational premillenialists. This means they've take a system developed in Covenant theology and translated into a (usually progressive) dispensationalist framework. I mean holy cow that is HUGE. Not many theological systems are that fluid. Of course I wouldn't say they can do it consistently but how many modern Reformed folk actually know the difference between Covenant theology and dispensational thought?
