Because of a conversation I had last week you all get to read my answer.
“The LORD is one!” There is but one true God. There are not two, three or more. There is only one true God and many false gods (1 Corinthians 8:4-6). Because of this, some have denied the deity of Christ. Some have denied that The Holy Spirit is God. Some have even denied that the Holy Spirit is a person! They say that only the Father can be God because there is only one God and if Jesus and the Holy Spirit was also God that would make three. I suppose that reasoning would be sound if the word “one” in the phrase “one God” always referred to a mathematical one.
In Deuteronomy 4:35, the term “LORD” in these passages is a translation of the Hebrew name “Jehovah.” So, “Jehovah, He is God, there is no other besides Him” is an accurate translation of the above verse. The earlier passage could be translated this way: “Hear O Israel! Jehovah is our God, Jehovah is one!”
However, the word translated “God” (Elohim) is plural in form. That makes the sentence really interesting and deserving of very careful consideration: “Hear O Israel! Jehovah is our God (plural), Jehovah is one!”
Add to this one other very important point: the Hebrew word translated “one” is “echad.” This word refers to a combined or united one made up of more than one part! Perhaps the easiest understood examples of how this word can be used is found in the first two chapters of the Bible.
(Genesis 1:5). Here, we have two parts (light and darkness) making up one day.
(Genesis 2:24). Here we have two persons becoming one. After doing so, are they no longer two distinct persons? They have not become mathematically one person. They are two individuals who have become united as one without losing their individuality. The point is this: Jehovah is one God. But this does not mean that He is one person any more than a husband and wife are one person because they are married.
Matthew 28:19 mentions three distinct entities united in one name, or authority. It is a fact that the Bible refers to each of these three as “LORD” or “Jehovah.”
The Father is referred to many times as “Jehovah” and as far as I know there is little controversy here. However, for the record, here are some references to consider: (1 Chronicles 29:10; Romans 1:7; 1 Corinthians 1:3).
Christ, the Son, is also referred to in the Bible as “Jehovah” For example, the LORD of hosts (the Father) will one day send the LORD (the Son) to this world to “dwell in your midst” according to one prophecy (Zechariah 2:8-11). Both the Sender and the One sent are referred to as “Jehovah” or “LORD.”
The Hebrew writer quotes several Old Testament passages which speak of “God” or “Jehovah” and apply them to Jesus, the Son (Hebrews 1:6-12; especially vs. 10 and Psalms 102:1,12,24,25).
Jehovah identifies Himself to Moses as “I AM” out of the burning bush and Jesus identifies Himself to the people as “I AM” as well (Exodus 3:14; John 8:24, 58).
Isaiah prophecies of John’s ministry as one who would “clear the way for the LORD (Jehovah) in the wilderness” and “Make smooth in the desert a highway for our God.” (Isaiah 40:3). This was fulfilled by John preparing the way for Jesus; Jesus is the One to whom Isaiah referred to as Lord and God according to (Matthew 3:3).
Many other examples such as Isaiah 44:6; 48:12 and Revelation 1:17-18; 2:8; 22:13,16 could be compared and cited. The point remains: Jesus is Jehovah.
The Holy Spirit is also referred to as “Jehovah” in the Bible. When Isaiah answered the Lord’s call unto the office of prophet there was a pressing need in the land. “And I heard the voice of the Lord, saying, ‘Whom shall I send, and who will go for us?’ Then I said, ‘Here am I. Send me!’” (Isaiah 6:8, 9; cf. vs. 3,5). The Lord of vs. 8 is the LORD (Jehovah) of vss. 3, 5). Jehovah spoke to Isaiah.
Would the term “LORD” or “Jehovah” refer to the Father, the Son or the Holy Spirit? There is a way to know for sure. The New Testament refers to this verse and informs us that “LORD” here refers to the Holy Spirit “rightly speaking through Isaiah the prophet...” (Acts 28:25).
Also, the Old Testament speaks of the coming of a New Covenant; (Jeremiah 31:33). It is the “LORD” or “Jehovah” that made this declaration! The New Testament further identifies the One making the declaration as “the Holy Spirit” (Hebrews 10:15,16).
So, it is as we have already stated; the Father, the Son and the Holy Spirit are each referred to in the Bible as Jehovah. It is correct to refer to each of these three in this way. They are distinct; and yet they are also one.
“Then God said, ‘Let us make man in our own image...” (Genesis 1:26). Who made man? God did! Who helped God accomplish that task? No one helped; God did it all by Himself! Who is God speaking to and why use the term “us?” Our one God consists of more than one person.
How can one understand this concept of three but one? In discussing the attributes of the eternal God, there are many things that mortal minds cannot comprehend. But to deny something that the Bible so plainly teaches is a lack of faith. One God in three persons; the Father, Son and Holy Spirit.
