We don't have a long and elaborate list of statements for what we believe here. We like to think we're pretty basic in our beliefs with these being rooted in the ancient creeds of the Church.
The Nicene Creed
We believe in one God,
the Father, the Almighty,
maker of heaven and earth,
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,
begotten, not made,
of one Being with the Father;
through him all things were made.
For us and for our salvation
He came down from heaven,
was incarnate of the Holy Spirit and the Virgin Mary
and became truly human.
For our sake He was crucified under Pontius Pilate;
He suffered death and was buried.
On the third day He rose again
in accordance with 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,
who with the Father and the Son
is worshiped and glorified,
who has spoken through the prophets.
We believe in the one holy catholic, universal, 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.
The Nicene Creed was established in 325 at the First Council of Nicea where certain disputes the Church was facing were settled, such as the full divinity of Christ (a sect known as Arianism had arisen, which claimed that Jesus was merely a sort of superhuman, an ubermench), the official date of Easter, and the canonization of certain Church laws that prohibited things like self-castration.
It is a misconception that claims that this council established beliefs in the Trinity (which had been essentially established as we know it today over a century earlier) or the canonization of Scripture (which was actually a process that took centuries).
The Apostle's Creed
I believe in God the Father Almighty,
maker of heaven and earth;
And in Jesus Christ his only Son our Lord:
who was conceived by the Holy Spirit,
born of the Virgin Mary,
suffered under Pontius Pilate,
was crucified, dead, and buried;
the third day he rose from the dead;
he ascended into heaven,
and sitteth at the right hand of God the Father Almighty;
from thence he shall come to judge the quick and the dead.
I believe in the Holy Spirit,
the holy catholic and universal church,
the communion of saints,
the forgiveness of sins,
the resurrection of the body,
and the life everlasting. Amen.
The earliest instance of the Apostle's Creed is found in 390 from a Synod (meeting) in Milan.
