Greek Roots

The words behind the New Testament

Almost every keyword of the New Testament was an ordinary Greek word first — a business term, a civic term, an imperial announcement. Knowing what a word did before the New Testament picked it up is most of what a word study is for.

Agape

114 in the New Testament

ἀγάπη

agapē · love

Before the New Testament: A rather pale word in classical Greek — used, but never the first choice for love, and carrying no special nobility.

Greek had several words for love, and agapē was the least interesting of them. It was not the word for passion, and it was not the warm word for friendship. It was ordinary, and slightly colourless.

That is probably why the New Testament writers took it. A word without much history attached could be filled. They filled it with a love defined by what it does rather than what it feels — God so loved the world that he gave; love is patient, love is kind; greater love has no man than this.

The often-heard claim that agapē is “God's love” and phileō is “human love” is too tidy. The New Testament uses agapaō of people loving darkness rather than light, and of Demas, who loved this present world. The word carries the weight its sentence gives it.

Logos

329 in the New Testament

λόγος

logos · word, account, reason

Before the New Testament: A working philosophical term for the rational principle ordering the universe — used that way from Heraclitus onward, and taken up by the Stoics and by Philo of Alexandria.

Logos is much wider than “word.” It is a statement, a message, an account you give, a reason, the sense a thing makes. A shopkeeper's accounts are logoi; so is a speech; so is an argument.

By the first century it was also a technical term. Greek philosophy used it for the reason running through everything, and Philo — a Jewish thinker in Alexandria who died around AD 50 — used it for a divine intermediary between God and the world.

John opens his Gospel with it, and for thirteen verses a Greek reader could nod along. Then verse fourteen: the logos became flesh and pitched his tent among us. That sentence has no home in any of the philosophies. It is the point at which John stops borrowing.

Charis

153 in the New Testament

χάρις

charis · grace, favour

Before the New Testament: An ordinary social word: a favour done, the charm that makes it welcome, and the thanks that come back for it.

Charis belongs to a family. Chara is joy; charisma is a gift freely given; eucharistia is thanksgiving. The root idea is a gift and the gladness on both ends of it.

In the everyday Greek world, charis described the favour a patron showed a client — real generosity, but inside a system where favours were expected to be returned.

Paul keeps the word and cuts the return. Grace, in his letters, is a gift that cannot be repaid and is not meant to be, which is exactly why he can set it against wages and against debt.

Koinonia

18 in the New Testament

κοινωνία

koinōnia · fellowship, sharing, partnership

Before the New Testament: A commercial and civic word — a business partnership, a joint holding, having something in common with someone.

Koinōnia comes from koinos, “common.” Two men who owned a fishing boat together were in koinōnia. It is a word about shared property before it is a word about shared feeling.

That is why the New Testament can use it of a cash collection for poor believers in Jerusalem without any change of register. Fellowship, in this vocabulary, includes the bank account.

So the English “fellowship,” which now suggests coffee after the service, is a considerable softening. The first church's koinōnia is described in Acts as holding things in common.

Parousia

24 in the New Testament

παρουσία

parousia · arrival, presence, coming

Before the New Testament: The technical term for a royal or imperial visit: the king arrives, the city goes out to meet him, and a coin is sometimes struck to mark the year.

Parousia literally means “being present,” and Paul uses it that plainly — he apologises that his own parousia is unimpressive. But in the wider world it had a formal sense: the state visit of a sovereign.

Inscriptions and papyri from the Greek east use it exactly that way. A parousia was a public event, announced in advance, with the citizens turning out along the road.

That is the picture behind the New Testament's word for Christ's return, and it explains a phrase that otherwise sounds odd: believers are caught up “to meet the Lord in the air.” The word for that meeting, apantēsis, is the same one used for a delegation going out of the city to escort the arriving king back in.

Euangelion

73 in the New Testament

εὐαγγέλιον

euangelion · good news, gospel

Before the New Testament: The announcement of a public event worth celebrating — a battle won, an heir born, an emperor's accession.

Eu is “good” and angelia is “message,” and the compound was in ordinary use for the kind of news a herald shouts. It was not a religious word.

It was, however, an imperial one. A famous inscription from Priene in Asia Minor, set up around 9 BC, calls the birthday of Augustus the beginning of good news for the world.

Mark opens his book with “the beginning of the euangelion of Jesus Christ,” and readers in the Roman east would have heard the form of the sentence before they heard its content. The word for the empire's announcements was pointed at somebody the empire had executed.

Ekklesia

113 in the New Testament

ἐκκλησία

ekklēsia · assembly, church

Before the New Testament: The citizens of a Greek city, summoned out of their houses to assemble and vote.

The word is built from ek, “out,” and a verb for calling — the citizens called out to meet. It named a political body, and Greek cities had used it that way for centuries.

Luke shows the ordinary sense without meaning to. During the riot at Ephesus he uses ekklēsia three times in one chapter of a pagan crowd and a lawful town meeting.

It is also the word the Greek Old Testament uses for the assembly of Israel. So when the New Testament calls Christians the ekklēsia, it is claiming two things at once: this is the assembly of God's people, and this is a body with standing.

Pneuma

378 in the New Testament

πνεῦμα

pneuma · breath, wind, spirit

Before the New Testament: Air in motion — breath, a breeze, the blast from a bellows. Medical writers used it for the breath of life.

One Greek word covers breath, wind and spirit, exactly as the Hebrew ruach does. That overlap is not a Bible invention; it is simply how both languages happened to work, and it made translating the Old Testament into Greek much easier at this point than at most others.

It also lets Jesus make a pun no English Bible can keep. In John 3:8 the word appears twice in one sentence — the wind blows where it wills, and so is everyone born of the Spirit. Same word, and the sentence turns on it.

The English word “pneumatic” comes from the same root, and it is a useful reminder: this is a word about moving air before it is a word about theology.

Metanoia

22 in the New Testament

μετάνοια

metanoia · repentance, a change of mind

Before the New Testament: Changing your mind about something — reconsidering, thinking again after the fact.

Meta means “after” or “change,” and nous is the mind. Metanoia is what happens when you think again and it changes what you do.

The English “repentance” comes through Latin and carries an overtone of sorrow that the Greek does not require. Regret may come with it; the word itself is about the turn.

The Hebrew background pushes the same way. The Old Testament's word, shuv, means to turn around and go back — a change of direction, physically pictured.

Martys

35 in the New Testament

μάρτυς

martys · witness

Before the New Testament: A legal term: the person who testifies to what they have seen.

In the New Testament martys is still mostly a courtroom word. The apostles are witnesses of the resurrection in the plain sense — they say what they saw.

But the cost of saying it kept rising, and you can watch the word begin to slide. Revelation calls Antipas “my faithful witness, who was slain”; Stephen is remembered as the first to die for the testimony.

Within a century or so, martys had become “martyr” in the sense English now uses. The change is not a mistranslation. It is a record of what happened to the people who kept testifying.

Parakletos

5 in the New Testament

παράκλητος

paraklētos · one called alongside; advocate, comforter

Before the New Testament: Someone summoned to your side to help — in legal use, the friend who stands with the accused and speaks for them.

The word is built from para, “alongside,” and a verb for calling. A paraklētos is someone you send for, who then comes and stands with you.

English translators have never agreed on it: Comforter, Counsellor, Advocate, Helper, and sometimes just Paraclete left untranslated. Each catches part of it and misses the rest.

It occurs five times, four of them in Jesus' last talk with the disciples, of the Spirit — and once in 1 John, of Jesus himself. So the New Testament calls two persons by this name, which is part of the point of the passage where Jesus promises “another” one.

Arrabon

3 in the New Testament

ἀρραβών

arrabōn · deposit, down payment, pledge

Before the New Testament: A commercial term for earnest money — the first instalment that makes a contract binding, and that you forfeit if you walk away.

This word is a foreigner in Greek. It came in from Semitic traders — the Hebrew ʿerabon is the pledge Judah leaves with Tamar in Genesis 38 — and Greek business kept it.

It is not a symbol or a token. An arrabōn is part of the actual payment, handed over first, of the same substance as the rest.

Paul uses it three times of the Holy Spirit, and the force is precise: what believers have now is not a picture of what is coming. It is the first instalment of it.

Stauros

27 in the New Testament

σταυρός

stauros · cross, stake

Before the New Testament: An upright pole or stake — in a palisade, or driven in the ground. The Romans made it an execution device.

The word is blunt and the New Testament keeps it blunt. There is no euphemism anywhere: the thing is named for what it is.

Ancient sources describe the Roman apparatus in more than one configuration, and the Gospels give one detail that settles the usual picture — a titulus, the written charge, was fixed above his head, which requires an upright with a crossbeam.

Paul knew exactly how the word sounded to an audience. He calls his message “the word of the cross,” and immediately concedes it is foolishness to Greeks and a scandal to Jews.

Ichthys

20 in the New Testament

ἰχθύς

ichthys · fish

Before the New Testament: A fish. Nothing more — one of the most ordinary nouns in the language.

Early Christians read the five letters of this word as five initials: Iēsous Christos Theou Yios Sōtēr — Jesus Christ, God's Son, Saviour. That reading is genuinely ancient, and the evidence for it has dates attached.

The fish is also simply everywhere in the Gospels, because half the disciples fished for a living. Jesus calls them to catch men; he feeds crowds with fish; he cooks fish on a beach after the resurrection.

What is attested and what is legend about the fish as a Christian sign is set out in the signs section further down this page, with the sources named.

Monogenes

9 in the New Testament

μονογενής

monogenēs · one of a kind, only

Before the New Testament: Used of an only child, and of anything unique of its sort — a one-off.

The old translation “only begotten” reads the second half of the word as genn-, “beget.” The better reading takes it from gen-, “kind” — so: the only one of its kind, unique.

Hebrews settles the question by using it of Isaac, who was demonstrably not Abraham's only begotten son. Isaac was the only one of his kind: the son of the promise.

At John 1:18 the manuscripts differ — the oldest read “the only God,” a large body of later ones “the only Son.” This site does not hide that sort of thing; the manuscript wing has it.

Psyche

103 in the New Testament

ψυχή

psychē · soul, life, self

Before the New Testament: The breath of life, and so the life itself; in the philosophers, the soul as distinct from the body.

Psychē covers the same ground as the Hebrew nephesh: the life in a creature, the person themselves, sometimes the appetite. English has no one word for it, so translators switch between “soul” and “life” — sometimes inside the same paragraph.

That switching is worth noticing rather than resenting. In Matthew 16 the same noun is rendered “life” twice and “soul” once in three verses.

Greek philosophy tended to set the soul against the body and prefer the soul. The Bible does not: its hope is resurrection, which is a claim about bodies.

Signs made out of letters

The early church built four signs out of Greek letters. Each one here prints what is actually attested, with the source and the century — and where a familiar story turns out to have no ancient source, that is printed too. A true thing with a false story attached ends up being disbelieved along with the story.

The fish

The Greek word for “fish,” read as five initials: Jesus Christ, God's Son, Saviour.

Ichthys is just the Greek for “fish.” Read the letters as initials and you get a sentence: Iēsous Christos Theou Yios Sōtēr — Jesus Christ, God's Son, Saviour.

The wordplay is genuinely ancient and it is well documented, with named authors and datable inscriptions. It is one of the earliest Christian symbols there is.

The famous story about it, on the other hand, is not ancient at all — which is worth saying plainly, because a true thing with a false story attached ends up being disbelieved along with the story.

c. AD 180-200

The Abercius inscription, Hierapolis

A Christian epitaph speaks of “a fish from the fountain, mighty and pure, whom a spotless virgin caught.”

c. AD 200

Clement of Alexandria, Paedagogus III.11

Lists a fish among the devices a Christian may properly have cut into a signet ring.

c. AD 200

Tertullian, On Baptism 1

“We, little fishes, after the example of our ΙΧΘΥΣ Jesus Christ, are born in water.” The earliest surviving text to spell out the connection.

quoted early 5th century

Augustine, City of God XVIII.23, quoting the Sibylline Oracles

Sets out the acrostic in full and explains the ΙΧΘΥΣ reading — the clearest ancient statement of what the five letters stand for.

What the evidence does not show

The story that persecuted Christians used the fish as a secret password — one believer drawing an arc in the dust, a stranger completing it — appears in no ancient source. Not one. It is a modern retelling, and a good one, but it is not evidence. What the ancient evidence actually shows is a sign used openly: on rings, on tombs, on walls, by people who were not hiding it. The two-arc outline familiar from car bumpers is a twentieth-century revival, not an ancient shape.

The chi-rho

The first two letters of ΧΡΙΣΤΟΣ, Christ, folded into one mark.

Chi and rho are the first two letters of Christos. Laid across each other they make ☧, and by the fourth century the mark was everywhere — on standards, coins, sarcophagi and church walls.

The famous moment is AD 312, before the battle at the Milvian Bridge. Two ancient writers describe it, and they describe it differently.

before AD 312

Greek papyri and manuscripts

The chi-rho already existed as a scribal abbreviation in ordinary Greek writing. Constantine popularised a mark that was in use, rather than inventing one.

AD 312, written c. 315-320

Lactantius, On the Deaths of the Persecutors 44

Constantine is directed in a dream to mark his soldiers' shields with “the heavenly sign of God” before the battle at the Milvian Bridge. Lactantius was alive at the time.

written after AD 337

Eusebius, Life of Constantine I.28

Gives the fuller and more famous version — a cross of light in the sky and the words “by this, conquer” — and says the emperor told him so himself, under oath.

What the evidence does not show

The two accounts do not match: Lactantius has a dream and a shield-mark, Eusebius a daytime vision in the sky, written a quarter-century later and sourced to the emperor's own memory. Both are reported here because both are the evidence. Neither is corroborated by anyone else.

The staurogram

Tau and rho combined, written inside the words for “cross” and “crucify.”

This is the quieter and older of the two monograms, and most readers have never heard of it. In the earliest Gospel papyri, scribes writing the words for “cross” and “crucify” combined the tau and the rho into a single figure.

If the usual reading is right, it is the earliest surviving Christian picture of the crucifixion — and it is not a symbol placed beside the text. It is inside a word.

c. AD 175-225

Papyrus 45, Papyrus 66, Papyrus 75

The tau-rho compendium appears in the words stauros and stauroō in some of the earliest Gospel manuscripts that survive — roughly a century before the chi-rho became an imperial emblem.

What the evidence does not show

That the mark appears in those papyri is manuscript fact. That the scribes intended the loop of the rho as a head and the tau as a cross — a small picture of the crucifixion, written inside the word — is an interpretation. It is a strong one, and it is widely held; the scribes left no note explaining themselves.

The sacred names

A short list of holy words that Christian scribes contracted and ruled a line over.

Open any early Christian manuscript and the sacred names jump out: ΘΣ for God, ΚΣ for Lord, ΙΣ for Jesus, ΧΣ for Christ, each with a line ruled over the top.

The practice is nearly universal in Christian copies, and it spread so early and so completely that it may have started before the surviving manuscripts were written.

The detail worth pausing on is the company. From the earliest copies we have, the name of Jesus is treated with exactly the same reverence as the name of God.

from the earliest Christian manuscripts onward

The Greek papyri and the great codices

God, Lord, Jesus and Christ are contracted to their first and last letters with a stroke above, essentially universally in Christian copies — a habit with no exact parallel in Jewish or pagan manuscripts of the period.

Words that came into English through Greek — and are explained next door

Amen. Hallelujah. Hosanna. Abba. These are not Greek words. They are Hebrew and Aramaic words wearing Greek letters — carried into the New Testament untranslated, and then carried into English untranslated a second time. Because they belong to the other alphabet, they are explained in the Hebrew hall rather than repeated here.
