It is no wonder then that the Apostle Paul told Timothy in 1st Timothy 3:16, "And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory." How can the Son of God be His own Father? It is a mystery. But it is a mystery revealed in the Bible. The mystery does not involve a Trinity of persons in the Godhead. The doctrine of the Trinity was foisted on the 3rd century church as a means for the church to become the state religion. And much to the dismay of the Trinitarian theologians among us, God is One in His nature. Deuteronomy 6:4 says, "Hear, O Israel: The LORD our God is one LORD..." And while the verse of scripture translated "God," in the Hebrew is Elohim a plural form of the word, it would be a stretch to make it mean gods as if God were plural. The word god can apply to magistrates, or judges. In Strong's Hebrew-Greek dictionary the meaning is, "ĕlôhı̂ym (pronounced) el-o-heem' Plural of H433; gods in the ordinary sense; but specifically used (in the plural thus, especially with the article) of the supreme God; occasionally applied by way of deference to magistrates; and sometimes as a superlative: - angels, X exceeding, God (gods) (-dess, -ly), X (very) great, judges, X mighty."
I read some time ago, one Trinitarian theologian, (I guess he was) who said the word "God" implied a unity of the persons of the Godhead. So, being curious and wanting to be right, I went to where the Lord Jesus answered the question put to Him as to what the first commandment was? He replied in Mark 29:29b-30, "...The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment." Again I looked in Strong's Hebrew-Greek dictionary and found the word Jesus used for one was the Greek word "heis. "The Greek meaning of the word, again according the Dr. Strong is, "heis (pronounced) hice (Including the neuter [etc.] ἕν hen); a primary numeral; one: - a (-n, -ny, certain), + abundantly, man, one (another), only, other, some. See also G1527, G3367, G3391, G3762." A primary numeral; one? Well that settled it for me. I would rather take Jesus' word than all the theologians in the world.
