The Trinity: The Unity and Oneness of God

by | Updated December 8th, 2019

The trinity is one of the most important and foundational doctrines of the Christian faith. It is extremely important that we be well equipped and versed in what we believe concerning this doctrine.

Dr. Walter Martin said that cults twist the majority of Christians into doctrinal pretzels because we know what we believe, but not why. Peter said, “Sanctify the Lord God in your hearts and be ready always to give answer to every man that asks you a reason of the hope that is in you” (1 Peter 3:15). We are admonished to “Contend (fight) for the faith which was once delivered unto the saints” (Jude 3).

The term “trinity” is not mentioned in the Bible. It was first used in the second century to describe the Godhead, which is a biblical term (Colossians 2:9, Romans 1:20). So trinity is merely another word to describe the Godhead. The planet Jupiter existed before it was ever named. Therefore, just because the term trinity came along later, doesn’t make it any less valid.

For more information about the trinity read The Trinity: One God, Three Persons and Illustrations and Examples of the Trinity.

Deuteronomy 6:4 says, “Hear oh Israel, the Lord our God is one Lord.” Lord is Yahweh in the original and is singular. On the other hand, Elohim is plural for God. It could read, “Yahweh (singular) our Elohim (plural) is one Yahweh (singular).” This is referring to the oneness of God, but it also refers to plurality. There is no other way to properly explain this other than the trinity.

There is only one God.

There is only one God that we worship and serve. There are not many gods, but only one true and living God. The following scriptures make this fact abundantly clear:

God is a compound unity.

God is a compound rather than an absolute unity. There are plenty of places in scripture where God is speaking in the plural:

The following prophecy refers to each member of the trinity (Godhead) within the verse:

“I will pour out on the house of David and on the inhabitants of Jerusalem, the Spirit of grace and of supplication, so that they will look on Me whom they have pierced; and they will mourn for Him, as one mourns for an only son, and they will weep bitterly over Him like the bitter weeping over a firstborn” (Zechariah 12:10).

Notice how the pronouns are interchanged or intermingled in the verse “I will,” “They will look upon Me,” “They will mourn for Him,” and “They will weep bitterly over Him”. The wording here can only be explained by viewing it as the compound unity of the Godhead.

Let’s look at a few examples of compound unity in other things. Remember, no illustration is perfect, it merely sheds light on the subject. A wise man of ancient Greece once said, “Every illustration limps.” The following examples will help bring understanding to the composite unity of the Godhead (trinity). They will help us see this doctrine as a composite rather than a solitary unity.

Marriage. “For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh” (Genesis 2:24, Mark 10:8). Obviously, Adam didn’t become Eve, but they became as one before God.

A cluster of grapes. “Then they came to the valley of Eshcol and from there cut down a branch with a single cluster of grapes; and they carried it on a pole between two men” (Numbers 13:23-24). Moses sent twelve men to spy out the promise land and bring back samples of what the land had to offer. They brought back one cluster of grapes that was so large they had to carry it on a pole between two men. It was one cluster of grapes, clinging from the same stem, and drawing it’s life from the same source. There were many grapes within the one cluster.

A group of people. A group often says they “stand as one” in time of crisis, to defend themselves, to protest, or to fulfill some purpose:
