During undergrad trained under Dr. Rod Rosenbladt and Dr. John Warwick Montgomery. They both apply analytic philosophy to Christian thought. Dr. Montgomery wrote a book called Tractatus Logico Theologicus Despite its name, it is straightforward to read and is an excellent place to start in regards to the philosophy of Christian thought. I work for 1517 one of his publishers, enter code "hubski" at checkout for 15% off.
- C.S. Lewis Mere Christianity, and An Experiment in Criticism
- For Systematics the best reformation one is Philip Melanchthon's Loci Communes
- Modern lay level systematic Called to Believe by Dr. Steve Mueller (I studied systematics under Mueller, keep in mind this book is written for students who want to work in the church)
- Philosophy: Ayer Languge, Truth, and Logic Wittgenstein Tractatus Logico-Philosophicus
This is only the tip of the iceberg haha. What I tried to come up with is the intersection of faith, reason, and a basic look at a historical/systematic approach to doctrine.
