The Burning Bush

I have burned in many things, and I have never yet destroyed the thing I burned in. That is the whole difference between My fire and every other fire, and I chose a dry desert thornbush to teach it, because I wanted the lesson to be unmistakable.

He was eighty years old and he was hiding. Do not let the marble statues fool you: Moses came to that mountain as a man with a killing behind him and forty years of sheep between him and the palace he had fled. He had been a prince and was now a herdsman on his father-in-law's payroll, walking flocks across the back of a wilderness, and if you had asked anyone in Midian who he was, they would have said: an Egyptian, more or less, who married one of Jethro's daughters. Nobody was waiting for him. Egypt had a new Pharaoh. The Hebrews had a new generation of foremen with the same whips. Nothing was moving.

And I was moving.

I set a bush alight on the slope of Horeb — a bush of the kind that goes up like paper and is ash in a minute — and I held the flame inside it without letting it eat a single thorn. Then I waited to see what he would do, because I never simply seize a soul; I offer it something worth turning aside for. He turned aside. That was his whole greatness in one gesture: he said, I will turn aside now and see this great sight, why the bush is not burnt. A man too busy to be curious about a wonder would have kept the sheep moving. Curiosity, when it is the honest kind, is the beginning of prayer.

When I saw that he had turned aside to look, I called him by his name, twice — Moses, Moses — as I have called every soul I intend to overturn, twice and by name, because I do not deal in generalities. And I told him to take his sandals off, since the ground he stood on was holy. Understand what that meant: the ground had been ordinary the day before. Goats had walked on it. It was holy because I was there, and for no other reason, which is why holy ground can be a mountain in Sinai, a stable in Bethlehem, a cave in Lourdes, a hospital corridor at three in the morning where somebody is praying.

Then I said the thing that broke him. I told him I had seen. I had seen the affliction of My people in Egypt, I had heard their cry, I knew their sorrows — and the word I used for knowing is not the word for having information. It is the word for intimacy. Forty years of screaming into brickwork and they thought the sky was empty. It was not empty. It was full of a listening you could not have survived seeing.

And then I sent him, and he did what every one of you does when I send you. He argued. Who am I, that I should go to Pharaoh? He was right, of course, and that was the point: the question was never who he was. I answered him not with a compliment but with a promise — I will be with thee — which is the only qualification anyone has ever needed for anything I have ever asked.

He pressed further. He wanted a Name. He said the people will ask me the name of the God of your fathers, and what shall I say? Every god of that world had a name that fit in a mouth — a name you could carve, own, invoke, use, bury with your dead, put on a boundary stone. He was asking Me to become manageable.

So out of a burning bush I gave him four consonants and a sentence that has never been exhausted: I AM WHO I AM. Say to the children of Israel: I AM hath sent me unto you.

Hear what that Name refuses. It is not a description; it does not tell you what I am like, as if I were one item in a catalogue of gods with attributes. It is not a handle. It is pure being, spoken in the first person, and it means: I am the One who simply is, who was not made, who does not begin, who owes existence to nothing, and everything you can point to owes its existence to Me. And it means something warmer that Israel would spend a thousand years learning: I am the one who is here. I will be there as who I will be there. Not a god who was, in the stories of your grandfathers. A God in the present tense, permanently.

That Name became so holy to My people that they would not put it in their mouths, and I have never once been offended by that reverence — I would rather a people tremble at a Name than chatter it. And when the fullness of time came, a Man stood in the Temple courts and said before Abraham was, I am, and they picked up stones, because they understood exactly what He had said. They understood better than most of you who read it calmly.

One more thing about that bush, which the Fathers of the Church saw and the icon-painters of the East never stopped painting. A created thing, a common dry bush of no value, held the uncreated fire inside itself and was not destroyed but crowned. Centuries later I overshadowed a girl in Nazareth, and God Himself dwelt in her body, and she was not consumed — she was made whole. They call her the Unburnt Bush in the East for that reason, and they are right.

And when I finally came down in tongues of fire on a hundred and twenty frightened people in an upper room, I came in the same fire and with the same restraint. I sat on their heads and did not burn their hair. I have been sitting on the heads of My people ever since, and if you feel Me as heat and are afraid I will destroy you, look at the thornbush again. I do not burn to consume. I burn to make ordinary things holy without taking away one thorn of what they are.

The Record

Exodus 3:1–15 records the theophany at Horeb (identified with Sinai), in which Moses, then keeping the flocks of his father-in-law Jethro (Reuel) in Midian after fleeing Egypt, sees a bush burning without being consumed. God calls him by name from the bush, declares the ground holy, identifies Himself as "the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob," announces that He has seen the affliction of Israel in Egypt, and commissions Moses to confront Pharaoh. When Moses asks for the divine Name, God answers with the Hebrew phrase ehyeh asher ehyeh — rendered in the Vulgate as ego sum qui sum and in English as "I AM WHO I AM" — followed by the Tetragrammaton (YHWH), the four-letter Name traditionally left unpronounced in Jewish practice and read aloud as Adonai ("the Lord"). The Septuagint translates the phrase as egō eimi ho ōn, "I am the One who is."

The episode is cited within Scripture itself as foundational: Stephen recounts it in his speech before the Sanhedrin (Acts 7:30–34), and Jesus appeals to "the bush" passage as proof of the resurrection of the dead, arguing that God is called the God of Abraham, Isaac, and Jacob in the present tense (Mark 12:26–27; Luke 20:37–38). The Catechism of the Catholic Church treats the revelation of the divine Name at the bush in paragraphs 203–213 as the central Old Testament disclosure of God's nature, reading ego sum qui sum as an affirmation of God as subsistent Being itself while also naming Him as the God who is faithfully present to His people.

Patristic and liturgical tradition developed two readings of the bush. St. Gregory of Nyssa (Life of Moses, c. 390) reads it as the soul's ascent to the knowledge of God and as a figure of the virgin birth. Eastern Christian tradition names the Theotokos "the Unburnt Bush" (Neopalimaya Kupina in Slavonic usage), a title with its own iconographic type, on the grounds that Mary contained the divine fire without being destroyed by it; the Byzantine liturgical texts for Marian feasts use the image directly. The connection between the fire that does not consume and the tongues of fire at Pentecost (Acts 2:3) is a commonplace of Christian preaching rather than a defined doctrine.

St. Catherine's Monastery at the foot of Jebel Musa in the Sinai — built by order of the Emperor Justinian between 548 and 565 and continuously inhabited since, one of the oldest working monasteries in the world — encloses a chapel built over what tradition identifies as the site of the bush, and a bramble growing in its courtyard is shown to pilgrims as a descendant of it. No claim of scientific verification attaches to the plant; the site's significance is one of continuous veneration, and the monastery's library and icon collection are of first-rank documentary importance in their own right.
