Trinitarian Hints in the Old Testament

8 min read · 1,443 words

The standard Muslim objection to the Trinity is that the doctrine is foreign to the strict monotheism of the Hebrew Bible. On this view, the Trinity is a Hellenistic Christian invention, fixed at the Council of Nicaea in 325 AD under imperial pressure, and the Quran’s anti-Trinity verses (Q 5:73, Q 5:116, Q 4:171) condemn an aberration from the true monotheism God revealed to the Jews.

This is historically false. The plurality of persons in God is already in the Old Testament. The Christian Trinity is the explicit articulation of what the Hebrew Bible itself signals.

This page walks through the main pieces of evidence.

The “let us” verses in Genesis

When God speaks in the opening chapters of Genesis, he sometimes uses the plural:

“Then God said, ‘Let us make man in our image, after our likeness’” (Genesis 1:26)
“The man has become like one of us” (Genesis 3:22)
“Come, let us go down and confuse their language” (Genesis 11:7)

The traditional Jewish explanations are that this is a “royal we,” that God is addressing the angels, or that it is just a Hebrew way of speaking. None works well. A royal “we” is not a known feature of Biblical Hebrew. The angels are not the image-bearers of God; man is. And the Hebrew construction is too consistent across the passages to be coincidence.

The Christian reading takes the plural at face value. God is speaking with himself, internally, between the persons.

The Angel of Yahweh

A figure called the Angel of Yahweh appears repeatedly in the Old Testament. He speaks as Yahweh in the first person, accepts worship, and is identified by both the narrator and the people who meet him as Yahweh himself.

Hagar meets the Angel of Yahweh in the wilderness and afterward “called the name of the LORD who spoke to her” (Genesis 16:7-13)
At the binding of Isaac, the Angel of Yahweh swears “By myself I have sworn, declares the LORD” (Genesis 22:11-18)
Jacob wrestles with “a man” and afterward says “I have seen God face to face” (Genesis 32:24-30)
At the burning bush, “the angel of the LORD appeared” and then “God called to him out of the bush” (Exodus 3:2-6)
Gideon meets the Angel of Yahweh, realizes who he is, and Yahweh responds, “Peace be to you. Do not fear; you shall not die” (Judges 6:11-22)

The pattern is consistent. The Angel of Yahweh appears as a distinct figure from Yahweh in heaven, yet acts and speaks as Yahweh, accepts worship as Yahweh, and is called Yahweh. This is not Yahweh and a created angel. It is Yahweh and the Word through whom Yahweh acts in the world. Christians identify this figure with the Son before the Incarnation.

Two Yahwehs in one verse

Genesis 19:24 reads: “Then the LORD rained on Sodom and Gomorrah sulfur and fire from the LORD out of heaven.” Two Yahwehs in one sentence. One on earth raining sulfur, one in heaven sending it.

The Christian reading is that the Son on earth calls down judgment from the Father in heaven. Justin Martyr, writing in the mid-second century, records that this verse was a known difficulty in Jewish-Christian exegetical debate. The natural reading of the Hebrew gives you two divine persons.

The Word and Wisdom

The Hebrew Bible treats the Word of God and the Wisdom of God almost as persons. The Word goes out, accomplishes, returns (Isaiah 55:11). Wisdom speaks in the first person in Proverbs 8:22-31 and claims to have been with God before creation: “When he established the heavens, I was there… then I was beside him, like a master workman.”

Second Temple Jewish writers developed this Word-and-Wisdom tradition into a fuller theology. The Aramaic translations of the Hebrew Bible (the Targums), used in the synagogue, often replace “the LORD” with “the Memra of the LORD,” the Word. The Memra creates, speaks at Sinai, appears in the burning bush. The Memra is Yahweh in the form of his active presence.

When John’s Gospel opens with “In the beginning was the Word, and the Word was with God, and the Word was God” (John 1:1), he is not importing a Greek philosophical idea. He is using the language of the Jewish Memra tradition. The Word through whom God created (Proverbs 8, Psalm 33:6) has become flesh in Jesus.

Psalm 110: Yahweh and “my Lord”

Psalm 110:1 reads: “The LORD says to my Lord: ‘Sit at my right hand, until I make your enemies your footstool.’” In Hebrew, the first “LORD” is Yahweh and the second is Adoni (my Lord). David, the Psalmist, sees Yahweh address a second figure whom he himself addresses as Lord.

Jesus presses this against the Pharisees in Matthew 22:41-46: if David calls him Lord, how is the Messiah merely David’s son? The argument has force only because both Jesus and the Pharisees already read Psalm 110 as a messianic text. The messianic reading was Jewish, not a Christian invention.

The same psalm calls this figure “a priest forever after the order of Melchizedek” (Psalm 110:4). The figure is both king (at God’s right hand) and priest (after Melchizedek). In Israel, kings came from Judah and priests came from Levi. The two offices were strictly separated. The Messiah of Psalm 110 holds both at once.

Daniel 7: The Son of Man and the Ancient of Days

Daniel sees a vision of the heavenly throne room. The Ancient of Days (Yahweh) is on the throne. Then:

I saw in the night visions, and behold, with the clouds of heaven there came one like a son of man, and he came to the Ancient of Days and was presented before him. And to him was given dominion and glory and a kingdom, that all peoples, nations, and languages should serve him. (Daniel 7:13-14)

The “one like a son of man” approaches the Ancient of Days and receives worship from all nations. In the Hebrew Bible, worship belongs only to Yahweh. The Son of Man is therefore not a mere human; he is a divine figure receiving worship alongside the Father.

Jesus repeatedly calls himself the Son of Man, and at his trial before the Sanhedrin says, “You will see the Son of Man seated at the right hand of Power, and coming with the clouds of heaven” (Mark 14:62). He combines Psalm 110:1 and Daniel 7:13-14 in one sentence. The high priest tears his clothes for blasphemy. The charge makes sense only because everyone present understood Jesus had just claimed to be the divine Son of Man of Daniel 7.

The “two powers in heaven”

In 1977 the Jewish scholar Alan Segal published Two Powers in Heaven, a study of early rabbinic literature. He documented that the rabbis in the first and second centuries AD repeatedly polemicized against a Jewish theological position they called “two powers in heaven,” in which the Hebrew Bible was read as witnessing to a second divine person alongside Yahweh.

The polemic itself is evidence that the position was widespread enough within Judaism to require attack. The Christian doctrine of the Trinity is the explicit articulation of a “two powers” theology that was already a real reading of the Hebrew Bible before Christianity existed.

What the Quran condemns is not the Christian doctrine

When the Quran condemns “those who say Allah is one of three” (Q 5:73), no Christian church teaches that. The Christian doctrine is one God in three persons, not three deities.

When the Quran condemns the worship of “Jesus, son of Mary, and his mother as two deities besides Allah” (Q 5:116), no Christian church teaches that either. Mary is honored as the mother of God incarnate but never worshipped as a deity.

When the Quran tells Christians not to say “three” (Q 4:171), it identifies Jesus correctly as the Word of Allah and a Spirit from Him, but rejects the conclusion that connects the Word and Spirit to the Father as persons in the one God. The detailed engagement is in Trinity Misidentification of Foundations.

The Christian doctrine of the Trinity has roots in the Hebrew Bible the Quran calls Tawrat. It is not a Greek aberration. It is the explicit reading of what was already there.
