I believe He is the Son of God, the chosen King. But I don't believe in the Trinity. There is historical evidence to prove it wasn't believed upon in Judaism--and during the Apostle Period and a few years afterward. The fact that the Trinity concept--not particularly advocated until the birth of Catholicism (325 A.D.)--isn't a unique belief, shows it's not a signature hallmark of the Supreme Creator(s). I believe the One true God would show a distinction in His throne. 3 and up isn't an exclusive marking, neither is 1. However, how many spiritual faiths do you know that proclaim just TWO Supreme Beings (and no lesser or subordinates)?
In all my research on religion I've came across three religions advocating a Twinity (as some Trinitarians call it), but only one of them had distinguishing qualities about it. The one mentioned in the Bible about a Father and a Son, a Divine Family.
