Forgive me, but the question itself is predicated on a theological error. Jesus Christ is fully God and fully man, being God the Son, the Divine Logos. He is, to quote the Nicene Creed, part of the
Christian Forums Statement of Faith , of one essence with the Father, begotten of the Father before all ages, very God from very God. Please read the Christian Forums Statement of Faith as it provides scripture verses in support of each statement in the Nicene Creed.
Now, the fundamental error in your question is to ask if the Father is “still greater than the Son.” Holy Scripture identifies God as unchanging and immutable, and the doctrine of the Trinity is that God the Father, Son and Holy Spirit are coequal, coeternal and consubstantial. The three persons share one divine essence, while each posessing their own hypostasis (a complex Greek word that literally means “understanding,” but in the context of the Trinity it refers to the distinct underlying reality of each person).
Jesus Christ, the only begotten Son and Word of God, is coequal with and coeternal to God the Father, but also became fully Man at the Incarnation. Thus His humanity and divinity are united hypostatically, which makes Him the Incarnate Word of God. Furthermore, the Chalcedonian, Oriental Orthodox, and Assyrian churches all agree that His humanity and divinity are without change, confusion, separation, or division. They are distinct, and not confused, but united, and not separate or divisible.
The respect in which one could say the Father is superior to Christ is to say that the uncreated Divine Nature, which Jesus shares with the Father, is superior to the created Human nature, and while Jesus Christ and the Holy Spirit are uncreated, coequal and coeternal with the Father, the Father alone is unoriginate. However, in terms of their divinity, the Father, Son and Holy Ghost are coequal, and it was by Christ our God that all things were made (John 1:2).
Our Lord desires that we make ourselves an icon of the Trinity, in the Gospel of John praying that we might be one, just as He and the Father are one. And if we see Christ we have seen the Father.
Of particular Trinitarian importance are John 1:1-17 and John 14:1-11.
Because Jesus Christ is fully God, in His deity he is omniscient, just as the Father is omniscient.
My friends
@ViaCrucis @Jipsah @prodromos @MarkRohfrietsch @HTacianas @Shane R @concretecamper @chevyontheriver @Valletta and
@dzheremi are particularly well versed in Trinitarian theology. I suggest posing any further questions pertaining to the deity of Christ and the doctrine of the Trinity to them.
We collectively share a concern about the growing lack of theological literacy concerning the Trinity among many Christians, which is leading to many people inadvertantly subscribing to Arianism, which is the heresy that denies the deity of Christ and His consubstantiality with the Father, or Macedonianism , the related heresy which denies the deity and unique personal identity of the Holy Spirit, and Nestorianism, a severe theological error which while I suppose nominally compatible with Nicene Christianity, causes severe confusion by separating and dividing the deity and humanity of Christ, which are distinct but undivided and inseparable in Chalcedonian and Oriental Orthodox Christology.
Arianism I would note is also the doctrine of the Jehovah’s Witnesses, and to support their heretical belief they published their own “translation”, the New World Bible, in which John 1:1 is intentionally modified, as that text alone is sufficient to refute Arianism. Indeed the denial of the Trinity in one form or another is a unifying belief of all the cults, including Mormonism (the Mormons are Tritheists, believing the persons of the Trinity are three gods, and believe in more gods than that if one explores the greater depths of their theology), Christian Science, Unitarianism, etc.
