Is the Bible an Essential Doctrine?

Is belief in Christ's human will an essential doctrine? Mm-hmm. How about Christ's human mind? Oh, man. The last time I got grilled on theological triage, I looked back in cringe. Do Protestants have a place I could go to get the answers to those questions? No. There's no... Well, first of all, Protestantism is not one church. So do you know a church that does have those answers?
