A true Trinitarian believes that all three members co-existed together as equals.
None were 'begotten'in eternity.
Christ (as we now know him)in eternity, was the Word, not the Son.
The Sonship of Christ is a function of the Plan, which has a hierarchal structure in the Trinity.
The Word agreed to become the Son in time as part of that Plan.
'Begotten' means to 'born' from the Father, as the article admits, which means the Word would be less then the Father.
The Nicene Creed simply pushes Arianism back into eternity, hoping no one would notice, and then uses a lot of rhetoric to cover up what it is really teaching, that one member of the Trinity preceded another, when it states clearly that in the beginning that the Word was with God and the Word was God.
No one was begotten in eternity.
fortheDeclaration:
The Father in terms of “relationship” as in the eternal order of the Trinity [Father], the Father is viewed as the Source of Trinity, but that does not say Father, Son, and Holy Spirit are “not equal”. The Father, Son and Holy Spirit are equal in Nature and Divinity but the Son and Holy Spirit are distinct and thus “not called Father”
So in the Latin version of the Creed, it expresses first the consubstantial communion of Father and Son and states that the Holy Spirit Proceeds from both.
Christ as the “Word” and “Son” relate to the same Divine Person, so your making distinctions there is problematic.
Your statement:
“The Sonship of Christ is a function of the Plan, which has a hierarchal structure in the Trinity”
Ok, again, some “redflags” here “Functional Trinitarianism” is similar to Modalism which has as [Our Sunday Visitors Catholic Encylopedia notes, pp.677-678] its basic error, denying that the processions of the Son and Holy Spirit are the source of real distinctions among the Three Divine Persons. Modalism in general, understands the Father, Son, and Holy Spirit to be roles, functions or modes adopted by by the unpersonal Godhead for the purposes of the economy of salvation.
One can see in Modalism, the notion that the Godhead can’t be known as God only appears in 3 modes for the benefit of humanity. So in this context, one can see in your statement Christ (as we know him) in eternity was The Word, not the Son, which then suggest Christ before he became Incarnate was and is unkowable to us even after Christ was incarnate and born of the Blessed Virgin Mary and revealed God to us. Thus, while the Holy Trinity is always an eternal Mystery, Christ via the Incarnation revealed the Holy Trinity to us and thus allows us to get a small glimpse into what is an eternal mystery.
My friendly suggestion is for you to perhaps reevaluate your Trinitarian Theology and get away from the group you are affiliated with. Obviously, I would first suggest you become Catholic or next Eastern Orthodox. IF that is to big an adjustment, I would suggest you go to one of the Confessional Protestant Groups who still hold to the Truths of the Creed.
