The Ecumenical creeds is an umbrella term used in the Western Church to refer to the Nicene Creed, the Apostles' Creed and, less commonly, the Athanasian Creed. The ecumenical creeds are also known as the Universal creeds. These creeds are accepted by almost all mainstream Christian denominations in the West, including Reformed churches, the Roman Catholic Church, Anglican churches and Lutheran churches. Many Methodist churches accept the Nicene Creed and Apostles' Creed. The Eastern Orthodox Church accepts the Nicene Creed but does not use the Apostles' Creed or the Athanasian Creed.

A creed is a summary or statement of what one believes. It originates from the Latin credo meaning "I believe." The purpose of a creed is to act as a yardstick of correct belief. A creed is an epitome of what is required for orthodoxy, not a full definition. It was hoped that by memorizing this summary of the faith, lay people without extensive theological training could still recognize deviations from orthodox doctrines based on the Bible as interpreted in the Christian tradition. The term ecumenical can refer to efforts by Christians of different church traditions to develop closer relationships and better understandings. The term is also often used to refer to efforts toward the visible and organic unity of different Christian churches in some form.

We believe in the one true, living God.

Sovereign over creation

Humanity is the greatest creation, and

He gave us the capacity to love and reason. 

First Council of Nicaea (325) 

We believe in one God, the Father Almighty, Maker of all things visible and invisible. 

And in one Lord Jesus Christ, the Son of God, begotten of the Father [the only-begotten; that is, of the essence of the Father, God of God,] Light of Light, very God of very God, begotten, not made, consubstantial with the Father; 

By whom all things were made [both in heaven and on earth]; 

Who for us men, and for our salvation, came down and was incarnate and was made man; 

He suffered, and the third day he rose again, ascended into heaven; 

From thence he shall come to judge the quick and the dead 

And in the Holy Ghost. 

First Council of Constantinople (381) 

We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible. 

And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds (æons), Light of Light, very God of very God, begotten, not made, consubstantial with the Father 

by whom all things were made; 

who for us men, and for our salvation, came down from heaven, and was incarnate by the Holy Ghost and of the Virgin Mary, and was made man; 

he was crucified for us under Pontius Pilate, and suffered, and was buried, and the third day he rose again, according to the Scriptures, and ascended into heaven, and sitteth on the right hand of the Father; 

from thence he shall come again, with glory, to judge the quick and the dead; 

whose kingdom shall have no end. 

And in the Holy Ghost, the Lord and Giver of life, who proceedeth from the Father, who with the Father and the Son together is worshiped and glorified, who spake by the prophets. 

In one holy catholic and apostolic Church; we acknowledge one baptism for the remission of sins; we look for the resurrection of the dead, and the life of the world to come. Amen. 

Apostles' 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 of the Holy Spirit and born of the Virgin Mary, 

who suffered under Pontius Pilate, was crucified, died, and was buried, 

descended into hell, rose again from the dead on the third day, 

ascended into heaven and is seated at the right hand of God the Father almighty, 

who 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. Amen. 

 Athanasian Creed 

Whosoever will be saved, before all things it is necessary that he hold the catholic faith. Which faith unless every one 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 Essence. 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 coeternal. Such as the Father is; such is the Son; and such is the Holy Ghost. The Father uncreated; the Son uncreated; and the Holy Ghost uncreated. The Father infinite; the Son infinite; and the Holy Ghost infinite. 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 uncreated; nor three infinites, but one uncreated; and one infinite. 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 God and Lord; So are we forbidden by the catholic religion; to say, There are 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 before, or after another; none is greater, or less than another. But the whole three Persons are coeternal, and coequal. So that in all things, as aforesaid; the Unity in Trinity, and the Trinity in Unity, is to be worshipped. He therefore that will be saved, let him thus think of the Trinity.

Furthermore, it is necessary to everlasting salvation; that he also believe faithfully 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 [Essence] of the Father; begotten before the worlds; and Man, of the Substance [Essence] 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 is God and Man; yet he is not two, but one Christ. One; not by conversion of the Godhead into flesh; but by assumption of the Manhood into God. One altogether; not by confusion of Substance [Essence]; 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 God the Father Almighty, from whence he will come to judge the living and the dead. At whose coming all men will 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 truly and firmly, he cannot be saved.

We base our theology on "Only One God," as in John 1 and 1 Ephesians 4:5. From various doctrines, methods or styles where those parts are considered the best to our knowledge that make sense by reason. God is a single power defined as the One or All, composed of everything it has ever created. This supreme energy force does not rule over the Universe; He is the Universe and the Universal Christ. 

Theology of the Creationist 

 Biblical cosmology is the biblical writers' conception of the cosmos as an organized, structured entity, including its origin, order, meaning and destiny. The Bible was formed over many centuries, involving many authors and reflecting shifting patterns of religious belief; consequently, its cosmology is not always consistent. Nor do the biblical texts necessarily represent the beliefs of all Jews or Christians at the time they were put into writing: the majority of those making up the Hebrew Bible or Old Testament, in particular, represent the beliefs of only a tiny segment of the ancient Israelite community, the members of a late Judean religious tradition centred in Jerusalem and devoted to the exclusive worship of Yahweh.

The ancient Israelites envisaged a universe of a flat disc-shaped Earth floating on water, heaven above, underworld below. Humans inhabited Earth during life and the underworld after death; there was no way that mortals could enter heaven, and the underworld was morally neutral; only in Hellenistic times (after c. 330 BCE) did Jews begin to adopt the Greek idea that it would be a place of punishment for misdeeds and that the righteous would enjoy an afterlife in heaven. In this period, in considerable measure, the older three-level cosmology gave way to the Greek concept of a spherical earth suspended in space at the center of several concentric heavens.

The opening words of the Genesis creation narrative (Genesis 1:1–26) sum up the biblical editors' view of how the cosmos originated: "In the beginning, God created the heavens and the earth"; Yahweh, the God of Israel, was solely responsible for the creation and had no rivals, implying Israel's superiority over all other nations. Later, Jewish thinkers, adopting ideas from Greek philosophy, concluded that God's Wisdom, Word and Spirit penetrated all things and united them. Christianity, in turn, adopted these ideas and identified Jesus with the Logos (Word): "In the beginning was the Word, and the Word was with God, and the Word was God" (John 1:1). Like Dr. Ross, we, at EMMI, believe in progressive creationism, a view which posits that while the earth is billions of years old, life did not appear by natural forces alone but that a supernatural agent formed different lifeforms in incremental (progressive) stages, and day-age creationism which is an effort to reconcile a literal Genesis account of Creation with modern scientific theories on the age of the Universe, the Earth, life, and humans. Ross rejects the young Earth creationist (YEC) position that the earth is younger than 10,000 years or that the creation "days" of Genesis 1 represent literal 24-hour periods. Ross instead asserts that these days (translated from the Hebrew word yom are historic, distinct, and sequential, but not 24 hours in length nor equal in length. Ross and the RTB team agree with the scientific community that the vast majority of YEC arguments are pseudoscience and that any version of intelligent design is inadequate if it doesn't provide a testable hypothesis which can make verifiable and falsifiable predictions, and if not, it should not be taught in the classroom as science.
