For as it was not possible that the man who had once for all been conquered, and who had been destroyed through disobedience, could reform himself, and obtain the prize of victory; and as it was also impossible that he could attain to salvation who had fallen under the power of sin,-the Son effected both these things, being the Word of God, descending from the Father, becoming incarnate, stooping low, even to death, and consummating the arranged plan of our salvation, upon whom [Paul], exhorting us unhesitatingly to believe, again says, "Who shall ascend into heaven? that is, to bring down Christ; or who shall descend into the deep? that is, to liberate Christ again from the dead." Then he continues, "If thou shall confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shall be saved." And he renders the reason why the Son of God did these things, saying, "For to this end Christ both lived, and died, and revived, that He might rule over the living and the dead." And again, writing to the Corinthians, he declares, "But we preach Christ Jesus crucified; "and adds, "The cup of blessing which we bless, is it not the communion of the blood of Christ? " - St. Irenaeus, Against Heresies, Book III, Chapter XVIII, Section 2.

The Catholic Creed: The Athanasian Creed
Whoever wills his salvation before all else let him profess the Catholic faith.
For unless a person keeps this faith whole and entire, he will undoubtedly be lost forever.
Now the Catholic faith is this: that we worship one God in the Trinity and the Trinity in unity.
Neither confounding the Persons, nor dividing the Substance.
For there is one person of the Father, another of the Son, another of the Holy Spirit.
But the Father and the Son and the Holy Spirit have one divinity, equal glory, and coeternal majesty.
What the Father is, the Son is, and the Holy Spirit is.
The Father is uncreated, the Son is uncreated, and the Holy Spirit is uncreated.
The Father is infinite, the Son is infinite, and the Holy Spirit is infinite.
The Father is eternal, the Son is eternal, and the Holy Spirit is eternal.
Nevertheless, there are not three eternal beings, but one eternal being.
So there are not three uncreated beings, nor three infinite beings, but one uncreated being and one infinite being.
Likewise, the Father is omnipotent, the Son is omnipotent, the Holy Spirit is omnipotent.
Yet there are not three omnipotent beings, but one omnipotent being.
Thus the Father is God, the Son is God, and the Holy Spirit is God.
However, there are not three gods, but one God.
The Father is Lord, the Son is Lord, and the Holy Spirit is Lord.
However, there as not three lords, but one Lord.
For as we are obliged by Christian truth to acknowledge every Person singly to be God and Lord, so too are we forbidden by the Catholic religion to say that there are three Gods or Lords.
The Father was not made, nor created, nor generated by anyone.
The Son is not made, nor created, but engendered by the Father alone.
The Holy Spirit is not made, nor created, nor generated, but proceeds from the Father and the Son.
There is, then, one Father, not three Fathers; one Son, not three sons; one Holy Spirit, not three holy spirits.
In this Trinity, there is nothing before or after, nothing greater or less. The entire three Persons are coeternal and coequal with one another.
So that in all things, as is has been said above, the Unity is to be worshipped in Trinity and the Trinity in Unity.
He, therefore, who wishes to be saved, must believe thus about the Trinity.
It is also necessary for eternal salvation that he believes steadfastly in the incarnation of our Lord Jesus Christ.
Thus the right faith is that we believe and confess that our Lord Jesus Christ, the Son of God, is both God and man.
As God, He was engendered of the substance of the Father before time; as man, He was born in time of the flesh of His Mother.
He is perfect God; and He is perfect man, with a rational soul and human flesh.
He is equal to the Father in His divinity, but inferior to the Father in His flesh.
Although He is God and man, He is not two, but one Christ.
And He is one, not because His divinity was changed into flesh, but because His humanity was assumed unto God.
He is one, not by a mingling of substances, but by unity of person.
As a rational soul and flesh are one man: so God and man are one Christ.
He died for our salvation, descended to the waiting souls of the faithful departed, and rose from the dead on the third day.
He ascended into heaven, sits at the right hand of God the Father almighty. From there He shall come to judge the living and the dead.
At His coming, all men are to arise with their own bodies; and they are to give an account of their own deeds.
Those who have done good deeds will go into eternal life; those who have done evil will go into the everlasting fire.
This is the Catholic faith. Everyone must believe it, firmly and steadfastly; otherwise He cannot be saved.
Glory be to Thee, O equal Trinity, one God, before all ages, now and forever.
The rational soul mentioned herein is the functioning of the mind of the Son, Jesus Christ, in His mortal flesh. That flesh once united to the Immortal Son of God is one in His Person forever. The Immortal Person of the Son of God is whole and complete from before all time and creation in the bosom of the Father in the Holy Spirit. That Person includes His mind and mental faculties which are part of His Immortal soul. The proper understanding of Origen - and Irenaeus whom Origen met and was given understanding by Irenaeus when Origen was young – is this and not the heresies falsely attributed to Origen centuries after his death. The Holy Spirit is the unity and power and bond of love of the Father and the Son Jesus Christ. When Jesus Christ appeared to Abraham as one of three persons (Fn. 1) in the Old Testament - He ate food. This shows that the uncreated energy of the Son of God made a whole human body present one with His person whenever He so chose. The difference in that and the Incarnation is of absolute significance for us. When He took the flesh of the virgin Mary upon Him, He took the flesh of Adam and all men so that all men will be resurrected, but not all will be saved. Only the saints will be saved into the kingdom of heaven - all others are preserved for the eternal existence they will have in their sinful flesh that God will command to be in the lake of fire forever. The salvation of the saints into the heavenly kingdom and God’s forgiveness of the sins which any have committed while they were alive in their flesh in their one and only former life is only because of the Redemption of Jesus Christ upon His Most Holy Cross.
Fn. 1 the other two were angels who were not the Father and the Holy Spirit, but only represented the Father and the Holy Spirit.
