In the Trinity, the one divine being is three persons whereas one human being is only one person (source: Is The Trinity a philosophical contradiction?).

A "being" is an independently existing thing.

The Father, Son and Holy Spirit are not three "beings".

For instance, Adam is a human being, Eve is a human being and Seth is a human being. You have three human beings because you have three independently existing things.

But the persons of the Trinity are not independently existing things, so we cannot say that there are three divine beings. But rather the Trinity is one being existing as three divine persons.

The point is that they are not three separate things in the way Adam and Eve are three separate beings precisely because they cannot exist apart from each other.

The three do not exist independently. They cannot exist apart from each other. They are one being (literally, one independent thing) and thus, they are one God.

What is the Biblical basis that Trinity is "one being in three persons"?

Did the Scripture say that the Father, Son and Holy Spirit are not three separate beings?

Usually, the Trinity is defined as of one substance, nature, essence and being. This question specifically asked what exactly does "one being" mean in regards to the Trinity because being is different from nature and person. 'To be' means to exist. 'Being' means existing.

  • Being here translates essence (esse being the Latin of the verb to be). That in modern times the word changed its meaning to that of person is another matter altogether. In the case of humans, the essence or "being" would be the flesh (Genesis 2:24).

    I read the answers from that question and none of then addressed my question at all. That question focuses on the "threeness" of the Trinity. My question is specifically asking about the "oneness" of the Trinity, specifically of being "one being" as defined by my original question. Thus, my question is utterly unique in this case it is new.

    @Al Brown Requiring a set form of scripture words before you will accept a doctrine that includes such words is like Muslims demanding Christians show them in the Bible where it says, “Jesus is God”. We all know such an exact phrase is not there but we also know that God gradually reveals more of himself and his purposes in the unfolding of Bible books. We also all know that Jesus is a person (not a phantom) and that the Father and the Holy Spirit are spirit, not flesh. Then we put together all else revealed about those three and come up with the biblical Godhead Acts 17:29; Rom 1:20; Col 2:9

    My response seems to have been deleted by the thought police. Anyway I am not requiring anything. Asking about biblical basis for God being made of three persons does not imply it must be exact wording. I would think it comes down mostly to the holy spirit and father

My understanding is that the scriptures convey that three Divine Persons share one divine nature.

I and the Father are one. [John 10:30, Young's Literal Translation] . . .

. . . . expresses a shared nature but different personalities.

One could re-word this and say that three Divine Persons share one divine existence.

Fulness being an attribute of divine nature means that the divine nature is shared perfectly, in fulness.

And of His fullness (the Word made flesh) we all have received, and grace for grace.

[John 1:16, KJV]

For in him (Christ) dwelleth all the fulness of the Godhead bodily.

[Colossians 2:9, KJV]

But the word 'being', when it refers to 'human being', has a specific meaning in that human persons, although they share the characteristics of humanity do not actually share the same humanity, that is to say the same human body and the same human soul.

I think that this causes a confusion of wording.

So I therefore, myself, prefer to say that three Divine Persons share one divine existence.

That is to say, three Divine Persons, dwelling in a perfection of unity, co-exist in the fulness of one divine nature.

(This wording therefore expresses person, unity, being and nature.)

And I know that some word this as 'three Divine Persons share one divine essence'.

And in one Lord Jesus Christ, the Son of God, begotten of the Father [the only-begotten; that is, of the essence of the Father, God of God,] Light of Light, very God of very God, begotten, not made, consubstantial with the Father;

First Council of Nicea 325 - Wikipedia

Then, also :

... who, being in the form of God, thought it not robbery to be equal with God:

[Philippians 2:6 KJV]

Here, existence (being) nature (form) deity (God) and person (he) are seen together.

The Son of God exists (being) in the form or nature of deity. That is how his person exists and that is the form in which he exists : deity.

It is similar to the expression 'I am that I am' Exodus 3:14, which expresses the fact of existence (of being) - I am - and the mode of being or the form of being or the nature of being - that I am.

This existence, this form, he shares (equal with God) : it is an equivalent, an equal, mode of existence with God.

This form of being is a shared form of being - the form or nature in which he exists and which existence he shares : is deity.

It is one form of existence which is shared.

One mode of being - is shared.

  • they share the characteristics of humanity do not actually share the same humanity. Does this mean that a human person is not identical to the human nature because a human person is only part of the human nature? What do you mean by "do not actually share the same humanity"? I guess one human person has unique human traits (unique personality, genes, behaviour etc.) that is not existing in any other but that this one human person has generic human nature (body and spirit/soul) which is what every human person possesses

    @RadzMatthewC.Brown I would say that human persons share human nature (attributes of flesh, bones, blood, senses, soul, mind, spirit . . . and mortality). But human persons do not share the same human body. (Even in conjoined twins there is definite separation of mind and intellect.) But fulness being a divine attribute means that one nature is perfectly shared in Deity.

    To further Nigel J's point. John Hancock is A human but he is not humanity. The Father IS deity, the Son IS deity, and the Holy Spirit IS deity...they are not three examples OF deity. The Trinity has been very poorly illustrated by a Venn diagram. Commented Jul 26, 2020 at 19:27

    @Al Brown The answer starts with the statement, "the scriptures convey that three Divine Persons share one divine nature." If you then read the reasons that follow, to explain that statement, you may see the biblical support for saying that three Divine Persons share one divine nature.

The difficulty with this article written by Jacob Allee for CARM (20 June 2011) is that not one single verse from the Bible is given. Instead, the author uses a philosophical approach to show how the being of God is different to the being of a human. Here are the relevant quotes from his article:

The Bible teaches that within the one being that is God, there is a simultaneous existence of three coequal and coeternal persons;

[God] is also unique from human beings in that the totality of what God is contains three distinct persons as opposed to human beings who only have one person as part of their being.

God is one “being” who exists as three “persons,”

God is simply a different kind of being than human beings, containing more persons in His existence than humans.

Nowhere does he say that the three “persons” who make up the One Being of God are separate – distinct, yes, but not separate. This is what the Athanasian Creed [1] declares:

We worship one God in trinity and the Trinity in unity, neither confusing the persons nor dividing the divine being... And yet there are not three eternal beings, but one who is eternal; as there are not three uncreated and unlimited beings, but one who is uncreated and unlimited... Christian truth compels us to acknowledge each distinct person as God and Lord... and so we must worship the Trinity in unity and the one God in three persons.

Neither does he say that the Father, the Son and the Holy Spirit are three “beings”. Does he say “the persons of the Trinity are independently existing things”? If so, I can’t see it.

The Bible declares that there is only the One God (Deuteronomy 6:4; Galatians 3:20; Ephesians 4:5). The Hebrew word translated “one” in Deuteronomy 6:4 is ‘echad’. It means “unity,” not “singularity.” It is also used in Genesis 2:24 in referring to a husband and wife being “one” flesh. A husband and wife are not one as in a singular being. Rather, they are in unity with each other. There is a Hebrew word that means “absolute singularity,” ‘yachid’, but it is never used in the Hebrew Scriptures in reference to God.

Within the One Being of God subsists the three “persons” of the Father, the Son and the Holy Spirit. They are not “persons” in the sense that humans are persons, and this distinction is made clear in the article. I get the impression that Jacob Allee is not disagreeing with that in his article, although his wording could be clearer.

Trinitarian orthodoxy can be formulated on the basis of 3 sets of NT statements, each consisting of one primary and several supporting statements:

1. 'yet for us there is one God, the Father,' (1 Cor 8:6a)

"This is eternal life, that they may know You, the only true God," (Jn 17:3a)

Jesus answered, "The foremost [commandment] is, 'Hear this O Israel: The Lord our God, the Lord is one,'" (Mk 12:29)

[Here Jesus quoted the Shema: 'Shema Yisrael, YHWH eloheinu, YHWH echad.' (Deut 6:4).]

2. "I and the Father are one." (Jn 10:30)

[If Jesus was speaking in Hebrew, He probably said "Ani veha'av echad", ending with echad as in the Shema.]

In the beginning was the Word, and the Word was with God, and the Word was God. (Jn 1:1)

whose are the fathers, and from whom is the Christ according to the flesh, Who is God over all, blessed forever. Amen. (Rom 9:5)

Who, existing in the form of God, did not consider to be equal with God something to be grasped, (Phil 2:6)

No one has ever seen God. The only begotten God, the One who Is in the bosom of the Father, He has made Him known. (Jn 1:18)

Plus 5 passages where the Son is referred as "ho Theos" with a qualification: Mt 1:23; Jn 20:28; Tit 2:13; 2 Pet 1:1; 1 Jn 5:20.

3. The Son and the Father are really distinct personal subjects.

[While the above is not an NT statement, it is an unavoidable straightforward conclusion from many NT statements, such as:]

"You are My Son, the beloved; in You I am well pleased." (Mk 1:11b)

"For the Father loves the Son and shows Him all things that He does." (Jn 5:20a)

"As the Father knows Me, I also know the Father; and I lay down My life for the sheep." (Jn 10:15)

"But that the world may know that I love the Father, and as the Father has commanded Me, thus I do." (Jn 14:31)

"Now, Father, glorify Me together with Yourself, with the glory which I had with You before the world was." (Jn 17:5)

Correspondingly, there are 3 possible ways to fall from trinitarian orthodoxy, each by denying one of the statements:

  • Denial that there is one God = tritheism
  • Denial that the Son and the Father are one = Arianism
  • Denial that the Son and the Father are really distinct = modalism or Sabellianism

Of those ways to fall, the first to occur historically was modalism (Sabellius fl. ca. 215), but it was Arianism which presented the biggest threat to orthodoxy and prompted the Church to elaborate a precise formulation of trinitarian doctrine.

Since Arians denied that the Son and the Father were one, they had to interpret Jesus' words "I and the Father are one." (Jn 10:30) in the sense of only moral oneness and not ontological oneness. To counter that eisegesis, the orthodox sought for the right word to add to Jn 10:30 to convey unequivocally the sense of ontological oneness: "I and the Father are one"... what?

We arrive at the same question from four key statements by Jesus of his divinity that were not mentioned above: the 4 times in which He explicitely applied to Himself the divine Name in the first person revealed in Ex 3:14: "Ehyeh", "Ego Eimí", I Am": Jn 8:24,28,58 & 13:19. If each of the Father and the Son names Himself "Ego Eimí", "I Am", then Each is a distinct "I" but Both are the same... what?

The natural answer to that question was the term ousía, which derived precisely from the verb "eimí", "to be". So, the initial orthodox answer to the Arian challenge was: the Father and the Son are one ousía and two prósōpa, one being and two persons.

Now, in contemporary language the term "being" is ambiguous, and in principle could convey the sense of either ousía or hypostasis (the latter as synonym of divine Person, as was officially used since 382), though it sounds more like the former, with which it is etymologically related.

  • That was very interesting thanks. But also, the q refers to claims that God is three persons united as one. And asks for basis that He is three persons. Everyone instead addressed the basis for the claim that His three aspects are united. Apparently there is no basis for Him being three persons. But im very interested in such
