I am not an oneness Pentecostal; but I am a monotheists and I am Pentecostal; I am not a Trinitarian; actually I am a Christian Universalist
Rev. 5:7 speaks of the power and authority of God.
Dan 7:13: This verse is written in Aramaic and I find a bit vague???? You are presuming One like the son of man is Jesus, it could be but it is very vague. Also "Ancient of Days " is also very vague. The we in Genesis 3 is the name Elohim or god. Same word is used all though out the Bible including Ps. 82.
There are many names and descriptive titles of God in the scriptures. He is called Counselor, King, Shepherd, Rock, Shield, High Tower, Strong Arm, Saviour, Redeemer, Father, Yahweh, Elohim, El Shaddai, El Elyon, Jesus (Yahshua), and many, many others. Someone has said that there are about two hundred names for God in the Bible! The moment one begins to splinter the absolute wholeness that God is, to examine all His multi-faceted aspects and attributes, the number of splinters are as infinite as God is infinite. Each name of God, as He progressively revealed Himself, was a fresh and fuller revelation of the nature of God. One was a revelation of His Self-existence, another of His might, another was the unveiling of His grace. One revealed something more of His wisdom, another of His holiness, another of His tenderness, another of His exaltation and honor, another of His judgment, and so on.
Psalm 82
1 God standeth in the congregation of the mighty; he judgeth among the gods. (notice little g or Elohim)
2 How long will ye judge unjustly, and accept the persons of the wicked? Selah.
3 Defend the poor and fatherless: do justice to the afflicted and needy.
4 Deliver the poor and needy: rid them out of the hand of the wicked.
5 They know not, neither will they understand; they walk on in darkness: all the foundations of the earth are out of course.
6 I have said, Ye are gods (Elohim); and all of you are children of the most High.
7 But ye shall die like men, and fall like one of the princes.
8 Arise, O God, judge the earth: for thou shalt inherit all nations.
Let me ask you a question; God is a spirit not a person or three persons; where do you get in scripture God is a three persons.
