Pastors teachers and scholars. question?

of all the interesting people in the bible the one that gets my interest going the most (besides jesus). is Melchizedek. or how the kjv says mel-chis'e-dec. i have heard some stuff about him but not alot. for the bible to speak so high of a man i was just wondering who (or what) you think he is. i know he is the king of salem and the and the bible talks like he is another form of god in the flesh.
