INTRODUCTION
In summary, this doctrine reveals to man intimate details concerning, not only the plurality of God’s person, but also the level of unity that exists within this plurality. It’s a doctrine that we of ARC prefer to call the doctrine of the “TRI-UNITY;” three persons,
(not gods), in absolute unity.
Repeatedly throughout the history of the Christian Church, many organizations have sprung up seeking to redefine, in a number of hypotheses, the plurality, as well as the unity of the God of the Christian scriptures. The most prominent and enduring of these heresies is found in the following:
TRITHEISM –
This heresy teaches that the Godhead is really three separate beings forming three separate gods. Although Trinitarians are not, and have never been tri-theistic, Christians in the early church were often accused of being the tri-theists by those who either could not (or would not) understand the doctrine of the Trinity. A version of this theology is held today by Mormons, formally known as The Church Of Jesus Christ of Latter-Day Saints.1
MODALISM –
This teaching, popularized by the 3rd century heretic by Sabellius , erred in the opposite direction of Tri-theism. This is so in that although Sabellius spoke of the Father, Son, and Holy Spirit, he taught that these weren’t three persons at all, but rather, three manifes-tations or “modes” of existence of the one God. Thus, this teaching came to be known as “Modalistic Monarchianism.” A version of this theology is held today by groups calling themselves “Apostolic Pentecostals,” or “Jesus Only Pentecostals.”
ARIANISM –
Founded by the 4th century Alexandrian presbyter “Arius,” this view held that The Father alone is truly God, with the Son being His first creation, and the Holy Spirit being reduced to being an “active force,” To Arius, only The Father was uncreated. Christ’s being “begotten” of the Father meant that he was created by the Father. This view is held today by the Watchtower Bible & Tract Society, commonly known as Jehovah’s Witness-es.
The purpose of this ARC Perspective is to put to rest once and for all (hopefully) all speculation as to how THREE PERSONS can exist as ONE GOD. May God guide us in this effort. 
1. Mormons believe that the Trinity is a tri-theistic pantheon consisting of three separate gods, (the Father, the Son, and the Holy Ghost), that sits above the polytheistic group of gods that all Mormon men may become. The supreme God within this pantheon, to them, is “Heavenly Father.” So, in reality, Mormonism is polytheistic with a tri-theistic upper class.
