1.2.2.2 I Corinthians 12:4-6 (diversity of gifts):

"Now there are diversities of gifts, but the same Spirit. And there are differences of administrations, but the same Lord. And there are diversities of operations, but it is the same God which worketh all in all."

Before moving on to my own comments, let us first hear from the Eerdmans Bible Dictionary:

"Triadic formulas in the New Testament are often regarded as implying a developed doctrine of the trinity, but this is to read too much into them. 1 Cor. 12:4-6; 2 Cor. 13:14 are implicitly subbordinationist since they use the formula 'Lord (i.e., Christ)-Spirit-God,' differentiating the first two from God"

The Eerdmans Bible Dictionary, Editied by Allen C. Myers, p. 1020

If I were to say: "There are diversities of gifts, but the same Santa Claus. And there are differences of administrations, but the same government. And there are a diversity of operations, but the same God worketh all in all." Do God, the US government and Santa Claus now form another "Trinity"? Is this indeed how this verse was meant to be read? Is it impossible to receive "gifts," "administrations," and "operations" except from ONE person? There is a big difference between this verse and between saying "God, Jesus, and the Holy Ghost are one and the same." Even in the very best case, no one who reads I Corinthians 12:4-6 will claim that it explicitly states that the three are one, they themselves will have to admit that it only implies such a connection. So now we need to ask: Why would God Almighty need to resort to implying His triune nature if this is indeed what He intended? What is preventing Him from simply coming out and stating His intent clearly if this is indeed what He meant?

Why does everything have to be so abstract? If this is the true nature of God then why can't the Bible just come out and say "God, Jesus, and the Holy Ghost are physically joined in one being" or "God, Jesus, and the Holy Ghost are one and the same." Is this so very hard? Look at how much less space this would require. Look at how infinitely more clear and decisive that would be. Look at the clear cut decisiveness of Deuteronomy 4:39

"Know therefore this day, and consider it in thine heart, that the LORD he is God in heaven above, and upon the earth beneath: there is none else."

Or Isaiah 43:10-11:

"Ye [are] my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I [am] he: before me there was no God formed, neither shall there be after me. I, [even] I, [am] the LORD; and beside me [there is] no savior."

Or Zechariah 14:9:

"And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one."

God does not philosophize and speak all the way around matters. He doesn't beat around the bush. He speaks clearly and in no uncertain terms so that there can be no doubt as to what He meant. If God was indeed a Trinity why would He not simply just come out and say so, just as clearly and decisively as He does when He speaks about his uniqueness?
