Hello friends! Early in my seminary life, I wrote a paper on the Trinity that I always reference when I talk about the subject. It is more on the technical side of things, with a lot of deep theology. If this is your thing, enjoy!
We can never fully understand the Trinity, but we must strive to talk about God in a biblically-accurate way. The church fathers and other theologians have helped a lot in this area.
I've attached it as a PDF so that I didn't have to redo all the citations.
