God is one in being and 3 in person.
A being is that quality or that essence what makes you what you are, a person is that quality, or that essence that makes you, whom you are. For example, what I am is a human being, and who I am is JakofHearts.
The being = I am a human being
The person = I am JakofHearts
We are human beings and we share that, but none of you share essentially the type of person that I am. We are all different persons.
So the characteristic of a being is very different of a person. I am one being with one person, God is one being with three persons – Father, Son, and Spirit. Is there anything like that on this earth? No. But with God all things are possible; not only that but there is a revelation in the trinity – we see the deeper truths of God’s nature, of what does it mean to be the father?, what does it mean to be the son?, what does it mean to be the Spirit? These are different roles in the trinity and often times people see the terms
Son and exert inferiority to the Son. There are scriptures that show this,
“For my father is greater than I.” John 14:28.
For example, my father is the CEO of his company and I am under him, he’s at the top. In that sense he is greater than I am, but he is a human being just as I am and we are of the same blood. So my father’s being is essentially equal to mine. He’s a human being and I am a human being, we are equal in that sense; but his role is greater than mine, and for him to be greater makes me subordinate to him.
When Jesus says
“The father is greater than I”, the being is equal but the role is different. And this is how the Trinity all comes into focus when we read the Bible.
Some people say that the trinity is not present in the old testament. They say that this was something new that Christians came up with. I disagree. When we understand the New Testament and Jesus Christ’s teachings about his father and the Holy Spirit we begin to see the Old Testament with more clarity, and we begin to see the Trinity and the depth of His being.
Genesis 1:1 “In the beginning God created the heaven and the earth.”
Lets take that back in Hebrew, “Elohim created”. Elohim is plural meaning “gods”, then ‘created’ treats Elohim as singular, so in the first verse of the Bible we see plurality and singularity in the Godhead. And another example in Genesis chapter 1, God the creator refers to Himself as “us”. How can God refer to Himself plurally? God says, Let “us” create man in “our” image. God created man in “His” image. (Gen 1:26 & 3:22) There is plurality and singularity used interchangeably multiple times in the Godhead.
In the Shema this is what the Jews recite twice a day:
A very profound proclamation in a world of polytheism to be found. But that one word, “Echad” is not used to describe a singularity. For example, it is used to describe a cluster of grapes – you would refer to the entire cluster as one cluster; that is what the word “Echad” means. So even in the Shema we have shades of the Trinity.
The Trinity is clarified through the person of Jesus, and it explains so much of what happens in the gospel. I think the Trinity is one of the most beautiful teachings about the depth of God’s character and how He is unlike anything in this universe.
