I'm not oneness guy and i don't know or believe in this so called sock puppet theology.
My belief is simple; The Father/son/Holy spirit are authorities of God who came in the person of Jesus which means that God came to demonstrate sonship to us. While demonstrating sonship, He submitted to the authority of the Father and overcame sin. After overcoming sin, He assumes the authority of the Father while we assume the authority of the son and what makes this possible is that tha Father indwells the son in the form of the Holy spirit (understanding).
This is shown in John 14/15/16. For example:
John 14:
12Truly, truly, I tell you, whoever believes in Me will also do the works that I am doing. He will do even greater things than these,
because I am going to the Father.
13And I will do whatever you ask in My name, so that the Father may be glorified in the Son. 14If you ask Med anything in My name, I will do it.
John 16:
23In that day you will no longer ask Me anything. Truly, truly, I tell you, whatever you ask the Father in My name, He will give you.
24Until now you have not asked for anything in My name. Ask and you will receive, so that your joy may be complete.
Not that the disciples had not asked Jesus anything, what this means is that Jesus had not attained the authority of the Father and come into them as the Holy spirit to make them attain the authority of the son. This is why Jesus is saying He has not gone to the Father. Now when Jesus attains that authority, this is what He does:
John 16:
12I still have much to tell you, but you cannot yet bear to hear it.
13However, when the Spirit of truth comes, He will guide you into all truth. For He will not speak on His own, but He will speak what He hears, and He will declare to you what is to come.
14He will glorify Me by taking from what is Mine and disclosing it to you.
15Everything that belongs to the Father is Mine. That is why I said that the Spirit will take from what is Mine and disclose it to you.
And the place that He almost got direct:
John 16:
25I have spoken these things to you in figures of speech.
A time is coming when I will no longer speak to you this way, but will tell you plainly about the Father.
26In that day you will ask in My name. I am not saying that I will ask the Father on your behalf. 27For the Father Himself loves you, because you have loved Me and have believed that I came from God.
c 28I came from the Father and entered the world. In turn, I will leave the world and go to the Father.”
Very simple. Jesus is the Father.
