The Shema: Does ‘The LORD Is One’ Deny the Trinity?

Question 2116.

The Shema is Israel’s great confession of faith, recited morning and evening by devout Jews for three thousand years, and it stands at the head of every serious conversation about God’s oneness: “Hear, O Israel: The LORD our God, the LORD is one” (Deuteronomy 6:4). The name comes from its first Hebrew word, shema, “hear”. And the question before us is a serious one: does this verse, the bedrock of biblical monotheism, rule out the doctrine of the Trinity? Jewish objectors have long said yes; Muslims press the same point; and many a Christian has stumbled over how “the LORD is one” squares with Father, Son and Holy Spirit.

I want to show you that the Shema, rightly read, is not an embarrassment to Trinitarian faith but one of its foundations – so much so that the New Testament writers, all of them monotheist Jews who prayed the Shema, found room within it for the Lord Jesus without ever feeling they had abandoned it.

What the Shema Says

Begin with the words themselves, and with what follows them, because the confession was given with a command attached:

“Hear, O Israel: The LORD our God, the LORD is one. You shall love the LORD your God with all your heart and with all your soul and with all your might.”

Deuteronomy 6:4-5 (ESV)

Context first. Moses is preaching to the generation about to enter Canaan, a land swarming with baals and ashtaroth, a god for every hill, harvest and household. Against that crowded pantheon Israel’s confession plants its flag: Israel’s God is not one deity among the many, not a tribal specialist to be supplemented as needed. The LORD – YHWH, the personal covenant name – is our God, and the LORD is one. The immediate force is exclusivity and uniqueness: one LORD, with no rivals, no colleagues and no understudies. That is why the very next verse demands undivided love. One God can claim the whole heart; a pantheon can only ever take percentages.

Translators note that the Hebrew can be rendered several ways – “the LORD is one”, “the LORD alone”, “the LORD our God is one LORD” – and the ESV footnote lists them. But every rendering lands in the same place: total, exclusive devotion to the one true God. Whatever else the verse teaches, it teaches that monotheism is not negotiable.

What “One” Does and Does Not Claim

Here is where care is needed. The Hebrew word for “one” in Deuteronomy 6:4 is echad. Many interpreters, including dispensational scholars I respect such as Arnold Fruchtenbaum, point out that echad can describe a composite or compound unity: a man and his wife become “one flesh” (Genesis 2:24); the gathered waters are one; evening and morning make one day; in Ezekiel’s prophecy two sticks become “one stick” in the prophet’s hand (Ezekiel 37:17). Hebrew has another word, yachid, meaning an only or solitary one, and Moses does not use it here.

I find this observation genuinely suggestive, and I will not pretend otherwise – but let me be honest about its limits, because I would rather understate a good argument than overstate it. Echad is also the ordinary Hebrew word for plain old “one”, as in one tent peg or one king, so its presence here does not prove plurality within God. What it does establish is the negative point, and the negative point is enough: the Shema’s “one” does not assert that God is an undifferentiated solitary unit. It declares that God is one; it says nothing whatever about whether that oneness is simple or rich, lonely or eternally fellowshipped. The doctrine of the Trinity is not smuggled into the Shema, but neither is it shut out by it. For the positive evidence of plurality within the one God, the Old Testament offers stronger threads, which I have gathered in Is the Trinity in the Old Testament?

Jesus and the Shema

Now watch what the New Testament does, because this is where the question stops being abstract. When a scribe asked Jesus which commandment was first of all, He did not hesitate: “The most important is, ‘Hear, O Israel: The Lord our God, the Lord is one. And you shall love the Lord your God with all your heart…'” (Mark 12:29-30). Jesus recited the Shema. He affirmed it as the head of all commandments. Whatever the doctrine of the Trinity means, it cannot mean abandoning the Shema, because the second Person of the Trinity prayed it and preached it.

Yet this same Jesus said, “I and the Father are one” (John 10:30), accepted Thomas’s confession “My Lord and my God!” (John 20:28), and claimed the divine name outright: “before Abraham was, I am” (John 8:58). His hearers reached for stones precisely because they were Shema-shaped monotheists and understood exactly what He was claiming. Jesus held both truths in His own person: the LORD is one, and the Son is LORD. The earliest Christians, far from feeling the contradiction, made that double conviction the heart of their worship – how, exactly, one God exists as three persons is a question I have tackled in How can God be three persons yet one God?

Paul Expands the Shema Without Breaking It

The most stunning text of all comes from Paul – Pharisee, Hebrew of Hebrews, a man who had recited the Shema daily since childhood. Writing to Corinth about idols, he says: “yet 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 Corinthians 8:6). Look at the architecture of that sentence against the Shema’s own vocabulary: the LORD (one Lord) our God (one God) is one. Paul has taken the two great titles of the Shema and placed the Father within “one God” and Jesus within “one Lord” – inside the confession, not alongside it as a second deity.

That is either blasphemy or revelation, and Paul knew which. He was not adding a junior god to Israel’s confession – the whole argument of the passage is against the very existence of other gods. He was declaring that when Israel confessed one LORD all those centuries, the Son was always included in that name. The Shema, it turns out, was roomier than its reciters knew – not because “one” secretly meant “three”, but because the one God had not yet fully shown them who He eternally is.

One Essence, Three Persons: The Shema Kept

So let me state the relationship plainly. The doctrine of the Trinity does not say there are three gods; it says there is one God – one divine essence, undivided – who eternally exists as three distinct persons: Father, Son and Holy Spirit. The Shema guards one flank of that doctrine, and guards it fiercely: against tritheism, against any pantheon, against every dilution of monotheism. The New Testament reveals the other flank: the persons. Strip away either side and you fall into error – three gods if you lose the Shema, a flat unitarianism that cannot account for Jesus if you lose the rest, as I have set out in What is the doctrine of the Trinity?

And notice, finally, that the demons themselves confirm the confession while missing its comfort: “You believe that God is one; you do well. Even the demons believe” – and shudder (James 2:19). The Shema was never meant to be bare arithmetic assented to from a safe distance. It comes welded to a command: love this one LORD with everything you are. Orthodoxy about God’s oneness, without love for God’s person, leaves you no better off than the shuddering spirits.

So, now what?

First, recite it. There is a reason Israel bound the Shema to the doorframe and the hand and taught it to children at bedtime: confessions shape souls by repetition. A Christian can pray the Shema with fuller understanding than Moses’ first hearers – one LORD: Father, Son and Spirit – and I suspect our scattered, distracted devotion would be steadied by saying so, out loud, at the start of the day.

Second, let the “one” do its surgical work. The Shema’s real rival in your life is probably not a doctrine but a pantheon – the quiet modern baals of money, approval, security and comfort, each claiming its percentage of your heart. “The LORD is one” means the LORD does not do percentages. All your heart, all your soul, all your might: the maths of the Shema has never changed.

And third, marvel that the one God of the Shema has a face. The confession Israel guarded through exile and fire was always, in the fullness of time, going to be spoken aloud by its own Author on a Galilean hillside. The LORD who is one loved you with all His heart, soul and might first – at a cross. Will you love Him back with anything less?
