This post includes the wording of three main Catholic Creeds: The Apostles Creed, the Nicene Creed, and the Athanasian Creed, which I referred to in a recent blog called Speaking of Creeds.
I believe in God, the Father almighty, creator of heaven and earth.
I believe in Jesus Christ, his only Son, our Lord. He was conceived by the power of the Holy Spirit and born of the Virgin Mary. He suffered under Pontius Pilate, was crucified, died, and was buried. He descended into hell. On the third day he rose again. He ascended into heaven and is seated at the right hand of the Father. He will come again to judge the living and the dead.
I believe in the Holy Spirit, the holy Catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting.
We believe in one God, the Father, the Almighty, maker of heaven and earth, and of all that is, seen and unseen.
We believe in one Lord, Jesus Christ, the only Son of God, eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten, not made, one in Being with the Father. Through him all things were made. For us men and for our salvation, he came down from heaven: by the power of the Holy Spirit he was born of the Virgin Mary, and became man. For our sake he was crucified under Pontius Pilate; he suffered, died, and was buried. On the third day he rose again in fulfillment of the Scriptures; he ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and his kingdom will have no end.
We believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son. With the Father and the Son he is worshipped and glorified. He has spoken through the Prophets. We believe in one holy catholic and apostolic Church. We acknowledge one baptism for the forgiveness of sins. We look for the resurrection of the dead, and the life of the world to come.
Whoever wishes to be saved must, above all, keep the Catholic faith.
For unless a person keeps this faith whole and entire, he will undoubtedly be lost forever.
This is what the Catholic faith teaches: 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 boundless, the Son is boundless, and the Holy Spirit is boundless.
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 boundless beings, but one uncreated being and one boundless 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 begotten 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 begotten of the substance of the Father before time; as man, He was born in time of the substance 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 humanity.
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 into hell, 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.
