I am asked often what the difference between us (being oneness) and the Trinitarians are? The answer is simple...the doctrine of the oneness is defined by Rev. David Bernard in his book The Oneness of God (http://ourworld.compuserve.com/homepages/pentecostal/one-Top.htm):
The belief in only one God is called monotheism, which comes from two Greek words: monos, meaning alone, single, one; and theos, meaning God. Anyone who does not accept monotheism can be classified as one of the following: an atheist who denies the existence of God; an agnostic - one who asserts that the existence of God is unknown and probably unknowable; a pantheist - one who equates God with nature or the forces of the universe; or a polytheist - one who believes in more than one God. Ditheism, the belief in two gods, is a form of polytheism, and so is tritheism, the belief in three gods. Among the major religions of the world, three are monotheistic: Judaism, Islam, and Christianity.
Within the ranks of those labelling themselves Christian, however, there are several divergent views as to the nature of the Godhead. One view, called trinitarianism, asserts that there are three distinct persons in the Godhead - God the Father, God the Son, and God the Holy Ghost - but yet one God.
The doctrine of the oneness of God is found throughout the scripture including...
Deuteronomy 6:4
Hear, O Israel: The LORD our God is one LORD:
This scripture established the idea among the Hebrew nation that God was one and therefore Jews continue to be monotheistic. We can look in the scripture and see that God is one and even it is in scriptures that are often overlooked. For example, when Jesus was coming into Jerusalem on the colt...the people yelled out...
Luke 19:38
Saying, Blessed be the King that cometh in the name of the Lord: peace in heaven, and glory in the highest.
The people in Jerusalem that day recognized Jesus as the God of Deuteronomy 6:4. We continue to recognize Jesus as God and therefore the Biblical doctrine of monotheism is preached from pulpits across the world.
