Quicunque Vult
(The Creed of Athanasius)

Whosoever will be saved, before all things it is necessary that he hold the
catholic faith. Which faith except everyone do keep whole and
undefiled, without doubt he shall perish everlastingly.
And the catholic faith is this:

That we worship one God in Trinity, and Trinity in Unity, neither
confounding the Persons, nor dividing the Substance. For there is one
Person of the Father, another of the Son, and another of the Holy Ghost.
But the Godhead of the Father, of the Son, and of the Holy Ghost, is all one,
the Glory equal, the Majesty co-eternal. Such as the Father is,
such is the Son, and such is the Holy Ghost. The Father uncreate,
the Son uncreate, and the Holy Ghost uncreate.
The Father incomprehensible, the Son
incomprehensible, and the Holy Ghost incomprehensible.
The Father eternal, the Son eternal, and the Holy Ghost eternal.

And yet they are not three eternals, but one eternal.
As also there are not three incomprehensibles, nor three uncreated,
but one uncreated, and one incomprehensible.

So likewise the Father is Almighty, the Son Almighty, and the Holy
Ghost Almighty. And yet they are not three Almighties, but one Almighty.

So the Father is God, the Son is God, and the Holy Ghost is God.
And yet they are not three Gods, but one God. So likewise the Father
is Lord, the Son Lord, and the Holy Ghost Lord. And yet not three Lords,
but one Lord. For like as we are compelled by the Christian verity
to acknowledge every Person by himself to be both God and Lord, so are
we forbidden by the catholic religion, to say, There be three Gods, or
three Lords. The Father is made of none, neither created, nor begotten.
The Son is of the Father alone, not made, nor created, but begotten.
The Holy Ghost is of the Father and of the Son, neither made, nor created,
nor begotten, but proceeding. So there is one Father, not three Fathers;
one Son, not three Sons; one Holy Ghost, not three Holy Ghosts.

And in this Trinity none is afore, or after other; none is greater,
or less than another; But the whole three Persons are co-eternal together
and co-equal. So that in all things, as is aforesaid, the Unity in Trinity
and the Trinity in Unity is to be worshipped. He therefore that will be saved
must thus think of the Trinity. Furthermore, it is necessary to everlasting
salvation that he also believe rightly the Incarnation of our Lord Jesus Christ.

For the right Faith is, that we believe and confess, that our Lord Jesus
Christ, the Son of God, is God and Man; God, of the Substance
of the Father, begotten before the worlds; and Man, of the
Substance of his Mother, born in the world; Perfect God and
perfect Man, of a reasonable soul and human flesh
subsisting; Equal to the Father, as touching his Godhead;
and inferior to the Father, as touching his Manhood.
Who although he be God and Man, yet he is not two, but
one Christ; One, not by conversion of the Godhead into flesh, but by taking
of the Manhood into God; One altogether,
not by confusion of Substance, but by unity of Person.

For as the reasonable soul and flesh is one man, so God and Man is one Christ;
Who suffered for our salvation, descended into hell, rose again the third day
from the dead. He ascended into heaven, he sitteth on the right hand of the Father,
God Almighty, from whence he shall come to judge the quick and the dead.
At whose coming all men shall rise again with their bodies and shall give account
for their own works. And they that have done good shall go into life everlasting,
and they that have done evil into everlasting fire. This is the catholic faith,
which except a man believe faithfully, he cannot be saved.
