Christ Deity as God is seen in scripture when we compare scripture with scripture, as eccles states in 12:
7Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
The Spirit of man [at death] returns unto God [elohim] who gave it ! Gen 1:1
Now compare that with stephens words at his death acts 7:
59And they stoned Stephen, calling upon God, and saying, Lord Jesus, receive my spirit.
60And he kneeled down, and cried with a loud voice, Lord, lay not this sin to their charge. And when he had said this, he fell asleep.
Notice, that He specifically calls upon God and says, Lord Jesus receive my Spirit, this points to Jesus as being God, Elohim of ecc 12:7
The reading of the King James Bible at Acts 7:59, which says: "And they stoned Stephen, calling upon God, and saying, Lord Jesus, receive my spirit", is a Scripture that has been tampered with, adding the word "God " in order to promote the trinity.
Such Bibles as The Montgomery New Testament, William's New Testament, International Standard Version, Weymouth's New Testament, Young's Bible, New International Version (2011), English Standard Version, Contemporary English Version, New Century Version, Common English Bible, Darby's Translation, Holman Christian Standard Bible, New International Reader's Version, New International Version - UK, and Today's New International Version (2005) do not contain the words "calling upon God " in an attempt to tie it in with the words "Lord Jesus" as a promotion of the trinity.
The Emphatic Diaglott reads: "and they stoned Stephen, as he was invoking and saying, "Lord Jesus, receive my spirit." The Westcott-Hort Greek interlinear master text literally reads: "And they-stone-cast the Stephen on-calling and saying Master (Lord)! Jesus ! receive the spirit of-me."
Thus, the addition of the word "God" after "on-calling" (Greek epikaleomai) is an attempt to seem together "God" as being Jesus Christ, and shows to what level individuals will stoop (and who call themselves "Christian") to further the wrong teaching that Jesus is God. The word "God" is not in the most ancient Greek manuscripts, such as the Codex Sinaiticus and Codex Vaticanus of the fourth century C.E.
Barnes’ Notes on the New Testament makes this honest admission: “The word God is not in the original, and should not have been in the translation. It is in none of the ancient [manuscripts] or versions.” How did the word “God” come to be inserted into that verse? Scholar Abiel Abbot Livermore called this “an instance of the sectarian biases of the translators.” Most modern translations, therefore, eliminate this spurious reference to God.
