Loraine Boettner on the Trinity

Loraine Boettner on the Trinity is a very interesting and unique read. I find Boettner on anything to be uniquely clear and valuable as a teacher of difficult, hard doctrine. I encountered him early on when I was learning Reformed theology, and I'm thankful I did. I tended to gravitate toward sources like him though, and there is no reason not to go back and revisit such on-the-mark sources we've learned the basics from in the past every now and then.

This one also is his classic work: Reformed Doctrine of Predestination. It is clear and strong and sets everything in bright sunlight.
