What does that even mean? "God has been His Father?" How can anyone be his own father?I mean God has always been His Father. Thus, He has always been the Son.
In order to make sense of the relationship beween the Father and the Son, you must use the terms properly. God has *not* always been the father of Jesus simply because Jesus, the man, has not always been manifest.
The revelation of Jesus began when he was produced as a human being, and not before. So no, God has not always been the Son! The Person who came to be revealed as "the Son" did indeed preexist the revelation of the Son. In that sense He was known as "the Word," or "God."
The Father has not always existed in the form of His revelation as the Father of Jesus. But as the Person of God He has indeed always existed. God came to be revealed as "the Father," in relation to Jesus, the Son, only when the Son came to be revealed as a man.I don't read the Father has always existed.
Prior to that, however, God had been known as the Father of mankind. But until Man had been created, God had not been known as the Father of mankind. Nevertheless, He had always been God, and had always had His Word, capable of expressing Himself as Father of both Man and Christ.
It makes little sense to say that the "Father is unbegotten." By definition, the Father preexists anything "begotten." However, He is not revealed as "the Father" until something is "begotten" that He Fathers, or until something is created that He is "Father" of.I don't read the Father has a beginning either. I did read no God existed before the Father nor one after Him. Therefore "if" the Father has a beginning it could not be by any other being. He is unbegotten.
In other words, God is eternally existent. But He is revealed in time in a particular role when He does something to give Him a title that represents that reality. We refer to God as "Father" only when in time God creates something that provides Him with the role of a father.
In the case of Jesus, God created a revelation of His own Person in the form of a human person, making Him Father of the Son. Both Persons were preexistent, but their roles only came to be known as such when God created a situation that called for that relationship to be revealed.
You say some orthodox things, and some things you say appear to muddle proper expression of things that need to be said properly to properly represent the relationship of Father, Son, and Spirit. If you present the Son as the *legal means* of our redemption, and the Spirit as the *local operation* of God's work in our present lives, then I think the language will work out well. It is indeed difficult to express the relationship of the transcendent to current material realities.
