I read a great global introduction to ecclesiology in seminary by Fuller prof Veli-Matti Karkkainen called An Introduction to Ecclesiology: Ecumenical, Historical & Global Perspectives. It really opened my eyes to a generous, global ecclesiology, freeing me from narrow Americanized conceptions of church. It’s a great intro in general but the global perspective is hard to beat.
JR Woodward is reviewing this book through a series of posts, so now you can read it through him! I have also picked up a couple other of Karkkainen’s global perspective books on systematic theology, which have been really good, one on Pneumatology and one on Christology. Enjoy!
