This is the Nicene creed in both English & latin. It was established by the first council of Nicea, and later edited by the Byzantines to fit their Eastern Orthodox teachings.
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.
Amen.
Credo in unum Deum, Patrem omnipotentem, factorem caeli et terrae, visibilium omnium et invisibilium. Et in unum Dominum Iesum Christum, Filium Dei unigenitum, et ex Patre natum ante omnia saecula. Deum de Deo, Lumen de Lumine, Deum verum de Deo vero, genitum non factum, consubstantialem Patri; per quem omnia facta sunt. Qui propter nos homines et propter nostram salutem descendit de caelis. Et incarnatus est de Spiritu Sancto ex Maria Virgine, et homo factus est. Crucifixus etiam pro nobis sub Pontio Pilato, passus et sepultus est, et resurrexit tertia die, secundum Scripturas, et ascendit in caelum, sedet ad dexteram Patris. Et iterum venturus est c** gloria, iudicare vivos et mortuos, cuius regni non erit finis. Et in Spiritum Sanctum, Dominum et vivificantem, qui ex Patre (Filioque) procedit. Qui c** Patre et Filio simul adoratur et conglorificatur: qui locutus est per prophetas. Et unam, sanctam, catholicam et apostolicam Ecclesiam. Confiteor unum baptisma in remissionem peccatorum. Et expecto resurrectionem mortuorum, et vitam venturi saeculi. Amen.
