We confess the faith that was delivered to the saints once and for all, as summarized by the ancient ecumenical creeds.
I believe in God the Father Almighty,
Maker of heaven and earth.
I believe in Jesus Christ,
his only-begotten Son, our Lord,
who was conceived by the Holy Spirit
and born of the virgin Mary.
He suffered under Pontius Pilate,
was crucified, died, and was buried;
he descended into hell.
The third day he rose again from the dead.
He ascended to heaven and is seated
at the right hand of God the Father Almighty.
From there he will come 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. Amen.
Athanasian Creed, Part 1:
Whoever desires to be saved should above all
hold to the catholic faith.
Anyone who does not keep it whole and
unbroken will doubtless perish eternally.
Now this is the catholic faith:
That we worship one God in trinity
and the trinity in unity,
neither blending their persons
nor dividing their essence.
For the person of the Father is a distinct person,
the person of the Son is another,
and that of the Holy Spirit still another.
But the divinity of the Father,
Son, and Holy Spirit is one,
their glory equal, their majesty coeternal.
What quality the Father has,
the Son has, and the Holy Spirit has.
The Father is uncreated,
the Son is uncreated,
the Holy Spirit is uncreated.
The Father is immeasurable,
the Son is immeasurable,
the Holy Spirit is immeasurable.
The Father is eternal,
the Son is eternal,
the Holy Spirit is eternal.
And yet there are not three eternal beings;
there is but one eternal being.
So too there are not three
uncreated or immeasurable beings;
there is but one
uncreated and immeasurable being.
Similarly, the Father is almighty,
the Son is almighty,
the Holy Spirit is almighty.
Yet there are not three almighty beings;
there is but one almighty being.
Thus the Father is God,
the Son is God,
the Holy Spirit is God.
Yet there are not three gods;
there is but one God.
Thus the Father is Lord,
the Son is Lord,
the Holy Spirit is Lord.
Yet there are not three lords;
there is but one Lord.
Just as Christian truth compels us
to confess each person individually
as both God and Lord,
so catholic religion forbids us
to say that there are three gods or lords.
