Brian,
It is the belief of the church and is supported by Scripture. You have done a fine job defending the "doctrine" of the Trinity and not just some "theory." I was afraid that FH would treat you as he treated me on this issue.  All we can do is pray that the Holy Spirit would convict his heart of the truth of the trinity. Good job brother.
