I am so glad you are enjoying my book, Simply Trinity: The Unmanipulated Father, Son, and Spirit (Baker). At the end, I provide a short bibliography. However, works on the Trinity are legion. Below is a working bibliography that can help you dive deeper into the doctrine of the Trinity. It is a working bibliography because I plan to keep adding more books to this list in the future. So keep returning to this bibliography to stay up on Trinity research. -Matthew Barrett
