I'm actually kind of surprised to see this kind of theology over the Triune God. A lot of this sounds like Oneness Pentecostalism, which isn't Christian nor does it have a correct understanding of who God is. While I'm sure many on here might be anti-Creedal, below is the Athanasian Creed that speaks of the Triune God.
Whoeer desires to be saved must above all, hold the catholic (Christian-not the Roman Catholic Church denom) faith.
Whoever does not keep it whole and undefiled will without doubt perish eternally.
And the catholic faith is this,
that we worship one God in Trinity and Trinity in Unity, neither confusing the persons nor dividing the substance.
For the Father is one person, the Son is another, and the Holy Spirit is another.
But the Godhead of the Father and of the Son and of the Holy Spirit is one: the glory equal, the majesty coeternal.
Such as the Father is, such is the Son, and such is the Holy Spirit
the Father uncreated, the Son uncreated, the Holy Spirit uncreated;
the Father infinite, the Son infiinite, the Holy Spirit infinite,
the Father eternal, the Son eternal, the Holy Spirit eternal
And yet there are not three Eternals, but one Eternal
just as there are not three Uncreated or three Infiinites, but one Uncreated and one Infinite
In the same way, the Father is almighty, the Son almighty, the Holy Spirit almighty;
and yet there are not three Almighties, but One Almighty
So the Father is God, the Son is God, and the Holy Spirit is God,
and yet there are not three Gods but one God
So the Father is Lord, the Son is Lord, the Holy Spirit is Lord,
and yet there are not three Lords, but one Lord
Just as we are compelled by the Christian truth to asknowledge each distinct person as God and Lord so also are we prohibited by the catholic (christian) religion to say that there are three Gods or Lords
The Father is not made nor created nor begotten by anyone
The Son is neither made nor created, but begotten of the Father alone
The Holy Spirit is of the Father and of the Son, neither made nor created nor begotten, but proceeding,
This line right above is heretical. To correct its FILIOQUE error, we should say, "The Holy Spirit is of the Father and of the Son, neither made, nor created, nor begotten, but proceeding from the Father alone. Then the so called "Athanasian" creed (it was not written by St. Athanasius!) would be Orthodox.
Thus, there is one Father, not three Fathers, one Son, not three Sons, one Holy Spirit, not three Holy Spirits, and in this Trinity none is before or after another, none is greater or less than another,
but the whole three persons are coeternal with each other and coequal so that in all things, as has been stated above the Trinity in Unity and Unity in Trinity is to be worshipped
Thereofre, whoever desires to be saved must hink thus about the Trinity,
But it is alsoc necessary for everlasting slavation that one faithfully beleive the incarnation of our Lord Jesus Christ. Therefore it is the right faith that we believe and confess that our Lord Jesus Christ, the Son of God, is a tthe same time both God and man. He is God, begotten from the substance of the Father before all ages, and He is man, born from the substance of His mother in this age. Perfect God and perfect man, composed of a rational soul and human flesh;
equal to the Father with respect to His divinity, less than the Father with respect to His humanity. Although He is God and man, He is not two but one Christ
one, however not by the conversion of the divnity into flesh but by the assumption of the humanity into God. one altogether, not by confusion of substance, but by unity of person. For as the rational soul and flesh is one man, so God and man is one Christ, who suffered for our salvation, descended into hell rose agin the third day from the dead. ascended into heaven, and is seated at the right hand of the Father, God Almighty, from whence He will come to judge the living and the dead. At His coming all people will rise again with their bodies and give an account concerning their own deeds. And those who have done good will enter into eternal life, and those who have done evil in eternal fire (properly understand, this doesn't ref. to works righteousness folks)
This is the catholic faith, whoever does not believe it faithfully and firmly cannot be saved
