"Hear, O Israel: Yahweh our God, Yahweh is one." — Deuteronomy 6:4

I. The Creed Before All Creeds

Before Nicaea, before Chalcedon, before any council of bishops gathered to define God in the categories of Greek metaphysics, there was a creed — spoken not in marble halls but in tents, at doorposts, at bedtime, at rising. It was the confession of a redeemed slave-nation standing at the edge of the promised land: the Shema.

The word shema (שָׁמַע, Strong's H8085) means far more than "listen." In Hebrew thought, hearing and obeying are a single act — to truly hear Yahweh is to yield to him. So Deuteronomy 6:4 is not merely a statement of information; it is a summons to exclusive covenant loyalty. And the content of that summons is stunningly simple: Yahweh our God, Yahweh is one.

For over a thousand years before Jesus was born, and in every synagogue since, this sentence has meant one thing to the people who received it: the God of Israel is a single divine person — a singular someone, not a composite something. Our task in this study is to restore that plain meaning and to show that Jesus and his apostles never revised it.

II. Covenant Context: One God, One Allegiance

Deuteronomy is structured like an ancient covenant treaty between a great king and his vassal people. In that world, the great question was never "how many persons subsist within your suzerain?" The question was: to whom do you belong?

Read the Shema in its immediate flow:

"Hear, O Israel: Yahweh our God, Yahweh is one. You shall love Yahweh your God with all your heart and with all your soul and with all your might." (Deut 6:4–5)

The confession of oneness grounds the command of undivided love. Because God is one — singular, personal, without rival — Israel's devotion must be one: singular, personal, without rival. A divided god could tolerate divided loyalty; the one Yahweh cannot.

Moses makes the referent unmistakable in the surrounding chapters: "Yahweh, he is God; there is no other besides him" (Deut 4:35), and again, "Yahweh, he is God in heaven above and on the earth beneath; there is no other" (Deut 4:39). The grammar is relentlessly singular and personal: he, him, I, me. This is not the language of an essence shared among persons. It is the language of a person.

III. The Lexical Heart: What Does Echad Mean?

The Hebrew word translated "one" is echad (אֶחָד, Strong's H259). It is the ordinary cardinal number — the word a Hebrew child would use to count: echad, shenayim, sheloshah — one, two, three.

  • "There was evening and there was morning, day one (echad)" (Gen 1:5).
  • "Abraham was only one (echad) man, yet he possessed the land" (Ezek 33:24).
  • "One (echad) witness shall not suffice" (Num 35:30).

In each case, echad means exactly what "one" means: not two, not three — one.

The Yachid Question

A common and understandable question arises: if Moses wanted to teach absolute singularity, why did he not use yachid (יָחִיד, H3173), sometimes rendered "only one"? The answer lies in usage. Yachid is a relational term meaning "only-begotten, beloved, solitary" — as in "take your son, your only son Isaac, whom you love" (Gen 22:2). It describes preciousness and uniqueness of relationship, not numerical quantity. No Hebrew writer would use yachid to say "God is numerically one," any more than an English speaker would say "God is an only child." Echad is precisely the right word for the job — the plain numeral.

IV. The Overwhelming Witness of the Pronouns

If the lexical argument were all we had, it would be strong. But Scripture provides something even more massive: the grammar of thousands of verses.

Yahweh refers to himself, and is referred to, with singular personal pronouns — I, me, my, he, him, his — on the order of twenty thousand times across the Hebrew Bible. Consider the great self-declarations of Isaiah:

"I am Yahweh, and there is no other; besides me there is no God." (Isa 45:5)

"I am the first and I am the last; besides me there is no god... Is there a God besides me? There is no Rock; I know not any." (Isa 44:6, 8)

"You are my witnesses, declares Yahweh... before me no god was formed, nor shall there be any after me. I, I am Yahweh, and besides me there is no savior." (Isa 43:10–11)

In every language on earth, singular personal pronouns identify a single person. If God were three persons, we would expect the divine self-testimony to reflect it — "we are Yahweh," "besides us there is no God." Instead, from Genesis to Malachi, God speaks as an I, never as a we in self-definition. The Shema simply crystallizes what the entire canon assumes.

V. Jesus and the Shema: The Messiah's Own Creed

Here we arrive at the most decisive moment in the entire discussion. In Mark 12:28–34, a scribe asks Jesus to name the greatest commandment. Jesus does not hesitate, and he does not innovate:

"The most important is, 'Hear, O Israel: The Lord our God, the Lord is one (heis, εἷς, G1520). And you shall love the Lord your God with all your heart...'"

The scribe responds: "You are right, Teacher. You have truly said that he is one, and there is no other besides him." And Jesus, hearing that he answered wisely, says: "You are not far from the kingdom of God."

Pause and let the weight of this land. A first-century Jewish scribe — a man whose entire understanding of the Shema was that God is a single divine person — affirms that reading to Jesus' face. If the scribe's understanding were deficient, this was the moment of all moments for the Messiah to correct him. Instead, Jesus commends him. The Messiah and the scribe stand together inside Israel's ancient confession, in perfect agreement.

And Jesus keeps this confession to the very end. In prayer to his Father he says: "This is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent" (John 17:3). The Father is the only true God; Jesus is his sent one — his shaliach, the commissioned human agent who bears the Father's name and authority without being the Father's rival or his equal in essence.

VI. Paul and the Shema: One God, One Lord

Did the apostle Paul expand the Shema to include Jesus within the divine identity? Read his words carefully:

"For us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist." (1 Cor 8:6)

Notice Paul's precision. The title "one God" is assigned — explicitly, exclusively — to the Father. Jesus receives a different title: "one Lord." And that title has a pedigree. It comes from Psalm 110:1, the most-quoted Old Testament verse in the New Testament: "Yahweh says to my lord (adoni): Sit at my right hand." The Hebrew adoni is the form used throughout Scripture for exalted human and creaturely superiors — never for God Almighty (which is Adonai). Peter draws the same conclusion at Pentecost: "God has made him both Lord and Christ, this Jesus whom you crucified" (Acts 2:36). Jesus' lordship is conferred, messianic, and functional — the exaltation of the Second Adam to God's right hand — not a claim to be the God of the Shema.

Paul, the former Pharisee who recited the Shema daily, dies with it intact: "There is one God, and there is one mediator between God and men, the man Christ Jesus" (1 Tim 2:5).

VII. Engaging the Traditional View

1. The Steel Man

The traditional Trinitarian position deserves its strongest and fairest statement. Thoughtful proponents argue as follows: The Shema teaches the unity of God's being, not the unipersonality of God. The word echad can describe a compound unity — as when a man and woman become "one (echad) flesh" (Gen 2:24), or when two sticks become "one" in Ezekiel 37:17. The plural form of Elohim may hint at richness within the Godhead. And in 1 Corinthians 8:6, scholars such as Richard Bauckham and N.T. Wright propose that Paul has taken the Greek Shema of the Septuagint — "the Lord our God, the Lord is one" — and distributed its two divine titles between the Father ("one God") and Jesus ("one Lord"), thereby including Jesus within the divine identity rather than adding a second god. On this reading, the New Testament does not abandon the Shema but discovers its hidden depth. This is a serious, textually engaged argument, and those who hold it do so out of reverence for Christ.

2. The Tension

Yet this reading faces significant difficulties from the text itself.

First, the "compound unity" claim mislocates the plurality. In Genesis 2:24, the plurality resides in the nouns and context — "the two shall become one flesh" — not in the word echad. Echad there still means exactly one: one flesh, one unit. A numeral cannot smuggle plurality into a sentence; it can only count what the sentence supplies. If I say "one team," the word "one" does not mean "many" — the word "team" does. But "Yahweh" is not a collective noun like "flesh" or "team"; he is a personal name borne by one who says "I."

Second, the plural form Elohim is standard Hebrew grammar for majesty and rank, and Scripture applies it with singular verbs to unambiguously singular individuals: Moses is made elohim to Pharaoh (Ex 7:1), Dagon is called elohim (1 Sam 5:7), Chemosh is elohim (Judg 11:24). No one infers multi-personality for Dagon.

Third, the Mark 12 exchange creates a genuine problem for the expanded reading: the scribe articulates the strictly unipersonal understanding — "he is one, and there is no other besides him" — and Jesus praises him. If the Shema secretly encoded tri-personality, the endorsement of a unipersonal reading by the Son himself is difficult to explain.

Fourth, the "Christological monotheism" reading of 1 Corinthians 8:6 must account for Paul's own words: he does not say "one God: Father and Son." He says "one God, the Father" — full stop — and then gives Jesus the adoni title of Psalm 110:1, a title Hebrew reserves for non-deity superiors. The verse reads most naturally not as a splitting of the divine identity but as the Shema plus the exalted Messiah beside it.

3. The Resolution

The Biblical Unitarian reading resolves every tension without remainder. The Shema means what Israel always heard: one singular divine person, Yahweh, the Father. Jesus recited it, affirmed it, and prayed it. Paul preserved it and set the risen human Messiah beside it — not inside it — as the one Lord whom the one God exalted. On this reading, nothing in the New Testament strains against the Old; the adoni of Psalm 110 sits at the right hand of the Yahweh of Deuteronomy 6, and the grand narrative of Scripture flows in one unbroken line from Sinai to the empty tomb to the coming Kingdom. The creed of Israel and the gospel of the Messiah are not rivals to be reconciled; they are one seamless testimony.

VIII. One Yahweh Among the Elohim: A Necessary Clarification

Restoring the Shema does not require flattening the supernatural world of the Bible. Psalm 82 opens with God taking his stand "in the divine council; in the midst of the elohim he holds judgment." Scripture freely acknowledges a populated spiritual order — sons of God, principalities, powers, the elohim of the nations (Deut 32:8–9).

The Shema does not deny that such beings exist; it denies that any of them is Yahweh, and it denies them Israel's allegiance. "Yahweh is one" means: among all the powers of heaven and earth, there is exactly one Most High, one Creator, one covenant God — and he is a single person who says "besides me there is no God" (Isa 44:6). The council serves by his permission; it never rivals his throne. Monotheism, biblically defined, is not the claim that only one spirit being exists — it is the confession that only One is God Most High.

IX. Living the Shema

The Shema was never meant to end in the head. Moses commanded that these words be bound on the hand, fixed between the eyes, written on the doorposts, taught to children in the way and at the table (Deut 6:6–9). Why? Because a singular God demands a singular heart.

When we confess that Yahweh our God — the Father of our Lord Jesus the Messiah — is one, we are not solving a math problem. We are declaring where our whole allegiance lies. We are joining the confession of Abraham, of Moses, of David, of the scribe in the temple court, and of Jesus of Nazareth himself, who loved the one God with all his heart, all his soul, and all his strength — even unto death — and whom that one God raised and seated at his own right hand.

Hear, O Israel. Yahweh our God, Yahweh is one. And the man who kept that creed perfectly is now the firstborn of the new creation, the guarantee that we, too, may love the one God with an undivided heart in his coming Kingdom.
