Biblical Roots: The Cry for Mercy
The phrase “Kyrie Eleison” — Greek for “Lord, have mercy” — does not appear as a fixed liturgical formula in the New Testament, but its direct antecedents are everywhere in the Gospels. The blind men and lepers who cry out to Jesus use the precise Greek construction: the blind men of Jericho calling out “Kyrie, eleison hemas” (Lord, have mercy on us), and the ten lepers who “lifted up their voices, saying, Jesus, Master, have mercy on us.” One of the documents notes this connection directly, describing the people’s response in the liturgy as “the publican’s prayer, adapted to the Christian worship” — a reference to the tax collector in Luke 18:13 who beat his breast and said “God, be merciful to me, a sinner” .
The Old Testament foundation is equally deep. The Psalms are saturated with cries for mercy — Psalm 69: “Save me, O God; for the waters are come in unto my soul” , and Psalm 22 (the crucifixion psalm) which Christ himself quotes on the cross: “O God, my God, why hast Thou forsaken me?” . In the Jewish synagogue tradition, the prayer “Eloha, who hast power over the life of all flesh, heal her, I beseech thee” shows the same posture of supplication that would carry over into Christian worship.
A key footnote in the ANF volumes explicitly identifies the biblical model: “The publican’s prayer, adapted to the Christian worship: ἱλάσθητί μοι, is the plea for mercy through propitiation. Luke xviii. 13” .
From Synagogue to Church: The Liturgical Bridge
The documents reveal that the first half of the early Christian liturgy — the part containing the Kyrie — was directly inherited from Jewish synagogue worship. One source describes this transition explicitly:
“Here ends the first part of the liturgy; that part which the Church had taken from the old use of the synagogues. The second part, the Christian liturgy, properly so-called, begins by the salutation of the bishop.”
So when the early church structured its worship, it retained the Jewish pattern of intercessory prayer. The deacon would intone a litany of petitions — for the peace of the world, the Church, bishops, the sick, travelers, children, the erring — and after each petition, the congregation responded with “Kyrie eleison” . This is not a later addition; it is the structural DNA of the earliest post-apostolic liturgies.
Where It Sat in the Early Eucharistic Liturgy
The documents give us a remarkably clear picture of the Kyrie’s placement. After the catechumens and penitents were dismissed, the Liturgy of the Faithful began. Here is the sequence:
- The faithful prostrate toward the East in prayer
- The deacon recites the litany (the “Great Intercession”) — petition after petition for the Church, the world, the suffering
- To each petition, the people respond: “Kyrie Eleison” — “Lord, have mercy”
- The litany concludes with “Save us, and raise us up, O God, for thy mercy’s sake”
- Then the bishop’s solemn prayer rises in the silence
In the Liturgy of St. James (one of the earliest extant liturgical forms), the people respond twelve times “Lord, have mercy” after the deacon’s bidding: “Let us all say fervently, Lord, have mercy” .
In the Clementine Liturgy (Apostolic Constitutions, Book VIII, ~4th century), the Kyrie Eleison appears as the congregational response to the deacon’s extended litany, which includes supplications “for the peace and good estate of the world; for the holy Catholic and Apostolic Church; for bishops, priests; for the Church’s benefactors; for the neophytes; for the sick; for travellers; for little children; for those who are erring” .
The East-West Divergence: Pope Gregory the Great’s Account
The most detailed document about the Kyrie’s early liturgical use comes from Pope Gregory the Great (c. 540–604 CE), writing to John, Bishop of Syracuse, in defense of his liturgical reforms. Gregory’s letter is a goldmine:
“Further, we neither have said nor now say the Kyrie Eleison, as it is said by the Greeks: for among the Greeks all say it together; but with us it is said by the clerks, and responded to by the people; and as often as it is said, Christe Eleison is said also, which is not said at all among the Greeks. Further, in daily masses we suppress some things that are usually said, and say only Kyrie Eleison, Christe Eleison, so as to devote ourselves a little longer to these words of deprecation.”
This reveals a critical divergence:
| Feature | Greek (Eastern) Practice | Roman (Western) Practice |
|---|---|---|
| Who says it | All the people together | Clerks chant it, people respond |
| Form | Kyrie Eleison only | Kyrie Eleison + Christe Eleison (alternating) |
| Frequency | Every liturgy in full | Daily masses shorten it; festivals lengthen it |
Gregory insists these are not innovations borrowed from Constantinople — rather, they are Roman customs that predate him. He also notes that the Kyrie in Rome is used as “words of deprecation” — a prolonged plea for mercy — and that in daily masses they would chant nothing else for a time, dwelling on these words alone .
The Trisagion Connection
The Kyrie also appears in close relationship with the Trisagion — the thrice-holy hymn: “Holy God, holy mighty, holy immortal, have mercy upon us” . One manuscript notes that the Trisagion is “found in all the liturgies, which proves a common source and original” . The Trisagion itself ends with a plea for mercy (eleison hemas), echoing the same spiritual posture as the Kyrie.
What’s Missing and Noteworthy
Several things stand out from what the documents do (and don’t) reveal:
No single founder. Unlike the Lord’s Prayer or the Creed, no one claims to have invented the Kyrie Eleison. It emerges organically — a biblical cry that became a congregational response, then crystallized into a fixed liturgical form as early as the 4th-century Apostolic Constitutions.
The synagogue origin is explicit but underdiscussed. The documents flatly state that the first part of the liturgy (the Kyrie-litany section) was taken “from the old use of the synagogues” . This is a remarkable admission of direct Jewish-to-Christian liturgical continuity, yet the documents don’t explore which specific synagogue prayers (possibly the Tefillah / Amidah with its petitions and responses) formed the direct model.
The Kyrie as a “people’s prayer.” One of the striking things across all the sources is how the Kyrie Eleison is consistently the voice of the congregation, not the clergy. In the Byzantine rite, everyone says it together. In the Roman rite, the clerks intone and the people respond. It stands as one of the oldest continuous congregational acclamations in Christian worship — a piece of the liturgy that has never belonged to the priest alone.
Dig Deeper:
- “The early liturgy’s first half was taken ‘from the old use of the synagogues’ — which specific Jewish prayers (the Amidah, the Hallel, or the Selichah penitential prayers) directly shaped the Kyrie litany structure?”
- “Pope Gregory says the Roman church shortened the Kyrie in daily masses to dwell on ‘these words of deprecation’ — what did they suppress, and what does that tell us about how the full Kyrie litany originally functioned in the Western rite?”
- “The Trisagion (‘Holy God, holy mighty, holy immortal, have mercy upon us’) appears alongside the Kyrie in the earliest liturgies — did these two prayers develop simultaneously or was one derivative of the other?”

Let me trace this connection systematically — from the Christian sources that claim synagogue origin, to the Jewish prayer texts themselves in the collection.Steps8 completed
I’ve traced the connection. Here’s what the documents reveal — and the answer is more specific than a general “it came from the synagogue.”
The Direct Link: The Shemoneh Esreh (Eighteen Benedictions)
The ANF volume drops a footnote that is effectively a smoking gun. Describing how the early Christian Church’s worship was structured from its beginning, it says the liturgy was “enriched by Gospels and Epistles, by psalms and hymns and spiritual songs, and by ‘the prayers’ (based upon the Shemoneh esre) which now began to be composed and multiplied in the churches” . The footnote cites Elucidation III in volume V of the same series for further detail.
The Shemoneh Esreh — literally “Eighteen” — is the core of Jewish statutory prayer, also called the Amidah (the “standing prayer”) or simply Tefillah (“the prayer” par excellence). According to the Talmud, it was formulated by “a hundred and twenty elders, among whom were many prophets” , and later established in a fixed order by Simeon the Pakulite in the presence of Rabban Gamaliel at Jabneh (c. 80–90 CE) . Maimonides’ Mishneh Torah explains why: after the Babylonian exile, Jews had become scattered and their language confused, so Ezra and his court “established eighteen blessings in sequence” so that “the prayers could be set in the mouths of everyone” .
This is the same structural logic the Christian litany would follow.
How the Amidah’s Structure Maps onto the Christian Litany
The Amidah has a tripartite structure that is strikingly identical to what we see in the Clementine Liturgy:
| Amidah Structure | Christian Litany Equivalent |
|---|---|
| Blessings 1–3: Praise — Avot (Fathers), Gevurot (Mighty Deeds), Kedushat Hashem (Sanctification of God’s Name) | The bishop’s opening prayer — “The grace of God Almighty…” followed by the Sursum Corda (“Lift up your hearts”) |
| Blessings 4–16: Petitions — For wisdom (Binah), repentance (Teshuvah), forgiveness (Selichah), redemption (Geulah), healing (Refuah), blessing of years, ingathering of exiles, restoration of justice, destruction of heretics, reward for the righteous, rebuilding of Jerusalem, Davidic kingdom, acceptance of prayer | The deacon’s litany — petition after petition for the peace of the world, the Church, bishops, priests, benefactors, neophytes, the sick, travelers, little children, the erring — and to each, the people respond “Kyrie Eleison” |
| Blessings 17–19: Thanksgiving — Avodah (Temple service restored), Hoda’ah (Thanksgiving), Sim Shalom (Peace) | The Eucharistic prayer — the great thanksgiving (anaphora) concluding with the Trisagion |
The Jerusalem Talmud confirms that the medial blessings of the Amidah are precisely about “the wants of man”: wisdom, repentance, forgiveness, deliverance, healing, blessing, unity, justice, the confounding of enemies, the building of the house of prayer . These are the same categories of need that appear in the deacon’s litany.
The Mechanism: From Silent Prayer to Congregational Response
Here’s the critical difference — and it’s where the Kyrie Eleison enters.
In the Jewish synagogue, the Amidah is recited in silence by each individual standing, while the sheliach tzibbur (reader) repeats it aloud. The congregation responds “Amen” after each benediction. In the Temple, the response was more elaborate: “Blessed be the name of His glorious kingdom for ever and ever” .
In the Christian adaptation, something changed. The deacon (not the bishop) chants the petitions, detailing each intention. And the congregation does not say “Amen” — they cry out “Kyrie Eleison” — “Lord, have mercy.” The liturgical scholar describing the early service notes the faithful answer, “and especially the children,” with the supplication Kyrie eleison .
This is not just a translation of Amen (“So be it”). It is a translation of the emotional register of the Amidah’s middle blessings into a single, repetitive acclamation of supplication. Every petition of the deacon evokes the same response: mercy.
Which Specific Jewish Prayer Was the Model?
The evidence points most strongly to the Amidah / Shemoneh Esreh as the direct model, for several reasons:
- The ANF footnote is explicit: “the prayers” were “based upon the Shemoneh esre” . The phrase “the prayers” (hai proseuchai) in Acts 2:42 was understood by the early Church to refer to fixed forms of prayer — and the best candidate was the established Jewish prayer of eighteen benedictions.
- The litany structure matches the Amidah’s petition sequence. The deacon’s litany follows the same pattern of moving from universal concerns (peace of the world, the Church) to specific needs (the sick, travelers, children, the erring) — exactly as the Amidah moves from general requests (wisdom, repentance) to specific ones (healing, blessing, ingathering). The Jerusalem Talmud describes the medial blessings precisely as “refer[ing] to the wants of man” .
- The “synaxis” was consciously modeled on the “synagogue.” The excursus on early worship states flatly that the Christian Church was “provided with a system of worship from the hour of its institution, the synaxis succeeding the synagogue” . And a separate excursus explicitly divides the liturgy into two halves: the first half (the litany with Kyrie Eleison) was “that part which the Church had taken from the old use of the synagogues,” while the second half was “the Christian liturgy, properly so-called” .
- The Selichah (penitential prayers) may explain the shift from “Amen” to “Kyrie Eleison.” The Amidah’s blessings 5–7 are Teshuvah (Repentance), Selichah (Forgiveness), and Geulah (Redemption) — explicitly penitential categories . The Christian liturgy intensified this penitential tone by replacing the declarative “Amen” with the supplicatory “Lord, have mercy.” The term “litany” itself (litanian) in early Christian usage specifically meant “penitential prayers” .
The Hallel (Psalms 113–118, sung at festivals) is a less likely candidate — it is praise, not intercession, and the Kyrie litany is overwhelmingly about petition.
The Timeline: When Did This Happen?
The documents suggest this was not a single act of borrowing but a process:
- c. 65 CE — Christians separate from synagogues but carry over the structure of prayer
- c. 80–90 CE — The Amidah is formally fixed at Jabneh under Rabban Gamaliel
- Late 1st–2nd century — The Christian “synaxis” develops alongside, adapting the Amidah’s petition structure but giving the congregation a new response: Kyrie Eleison
- 4th century — The Apostolic Constitutions (Clementine Liturgy) codify this in writing, showing a fully developed deacon’s litany with congregational Kyrie Eleison
- c. 590 CE — Pope Gregory the Great reports that the Roman church has modified the Kyrie by adding Christe Eleison and alternating between clerks and congregation
What’s Notably Missing
The documents confirm the Amidah as the structural model for the Christian litany, but they do not explain why “Kyrie Eleison” replaced “Amen” as the congregational response. The Jerusalem Talmud notes that in the Temple, the congregation responded “Blessed be the name of His glorious kingdom for ever and ever” to each benediction . The shift from that declarative blessing to a plea for mercy is a major theological move — one the documents describe without explaining.
Also worth noting: the Kaddish — another Jewish prayer with congregational responses (“Amen,” “Blessed be His great name”) — is structurally similar to the litany form but is never mentioned in the Christian sources as a model. The sources consistently point to the Amidah, and the Amidah alone.
Dig Deeper:
- “The Amidah’s petitions were recited silently and followed by ‘Amen’ — what evidence exists that the Christian litany’s shift from ‘Amen’ to ‘Kyrie Eleison’ was a deliberate theological choice tied to Gentile Christian identity?”
- “The documents say children responded ‘especially’ in the Kyrie — does this reflect a special liturgical role for children in the early Church, or a practical reason like literacy rates?”
- “The Jerusalem Talmud describes the Amidah’s medial blessings for ‘the wants of man’ — were there ever early Christian controversies about whether petitionary prayer of this kind was appropriate for the baptized versus catechumens?”

“The Trisagion (‘Holy God, holy mighty, holy immortal, have mercy upon us’) appears alongside the Kyrie in the earliest liturgies — did these two prayers develop simultaneously or was one derivative of the other?”
Webb
This is a fantastic question. Let me trace the relationship between the Kyrie Eleison and the Trisagion through the documents — when each appears, how they function liturgically, and whether one is derivative.
Let me search deeply across the Christian sources for direct statements about their origins and relationship.
I have strong foundational evidence. Now let me check whether any of the texts explicitly claim one prayer derives from the other, or whether the Trisagion might have a source in the Hebrew Scriptures’ “Holy, Holy, Holy” (the Kedushah/Qedushah) from Isaiah’s vision and the Jewish liturgy.
Now let me look at how the two function together in specific liturgical sources — do they appear as a pair, or in sequence? And let me also check whether the Trisagion has a “heavenly origin” claim attached to it.
Let me now check the actual liturgical texts to see how they function together — are they a pair, a sequence, or does one absorb the other?
Let me also check if the Trisagion is ever connected to a specific “heavenly origin” story, and whether the Christe Eleison (found only in the Western Kyrie) is an interpolation.
Let me now pull the actual pages from the key documents to see the full liturgical context of both prayers.
Let me also check what the ANF volumes say about the relationship between the two, and whether the Trisagion appears connected to Isaiah 6 or to a different origin story.
Let me now read the specific page from Codex Sinaiticus to see the full sequence.
Now let me get the full context of where the Trisagion appears in the liturgy of St. James.
Now let me look at the Eastern vs. Western liturgical patterns more closely, especially to see whether the Christe Eleison reflects the Trisagion’s threefold structure.
Let me check one more critical document — the exact text and context of the Trisagion’s first liturgical appearance.
Now I have a comprehensive picture. Let me assemble the findings.
Two Prayers, Two Origins — But a Third Unites Them
The documents tell a story that is more nuanced than “one derived from the other.” They reveal two independent prayer traditions that converge in the 4th–5th century liturgy in a way that later made them practically inseparable — but their origins are quite distinct.
The Kyrie Eleison: Organic, Biblical, Congregational
The Kyrie Eleison has no single origin story. It emerges from the dirt road of the Gospels — blind men, lepers, a tax collector crying out “Lord, have mercy” — and becomes the congregation’s voice in early Christian worship. As we’ve already established, it entered the liturgy as the people’s response to the deacon’s litany, adopted from the Jewish Amidah’s petition structure but replacing “Amen” with a supplicatory cry.
One document captures this beautifully: describing the blind men of Jericho crying out “Kyrie, eleison hemas” (Matthew 20:30–31), it notes this was “the cry of the afflicted to their Lord” . The same word, the same prayer. No angel dictated it. No council decreed it. It grew from the ground up.
The Trisagion: A Heavenly Origin Story
The Trisagion has a dramatically different claim to authority — a direct angelic revelation. The story appears in the Council of Chalcedon (451 CE) records:
“And the hymn of the holy Trisagion, which was brought down from heaven and delivered by the angel to the most holy Proclus, archbishop of Constantinople, as they of that city most certainly acknowledge” .
The story (recounted at the Council of Chalcedon, according to the document) is that during a great earthquake in Constantinople (c. 447 CE) that was shaking the city to pieces, a young boy was caught up into heaven and saw angels singing this hymn. He was brought back, taught it to the people and the emperor, and when they sang it, “the earthquake ceased immediately” .
The full text in the Codex Sinaiticus gives the Trisagion exactly as it was sung at the liturgy: “Holy God, holy mighty, holy immortal, have mercy upon us” — and immediately following it in the same manuscript: “Kyrie eleison, Kyrie eleison, Kyrie eleison” — thrice repeated .
This is not a coincidence of the manuscript. These two prayers, from two different origins, are already being sung back to back by the 4th century.
The Critical Distinction: Different Theologies, Different Functions
| Feature | Kyrie Eleison | Trisagion |
|---|---|---|
| Origin claim | Biblical/evolutionary — no single originator | Angelic revelation — delivered in Constantinople, 447 CE |
| Content | A plea for mercy — two words | A threefold doxology of God’s holiness framed by a plea for mercy |
| Theological focus | Humanity’s need — we need mercy | God’s nature — holy, mighty, immortal |
| Addressee | Unspecified — Kyrios could mean God the Father or Christ (ambiguity intentional) | Explicitly Trinitarian — the three attributes were understood by Eastern tradition as addressing each person of the Trinity |
| Originally from | The congregational litany response (from synagogue Amidah) | Possibly an expansion of the Sanctus (Isaiah 6:3: “Holy, holy, holy”) or a hymn from the Eastern monastic tradition |
The Trisagion’s threefold “Holy” recalls Isaiah 6’s Qedushah — the seraphim crying “Holy, holy, holy” — but the Trisagion adds something Isaiah’s vision lacks: the plea for mercy. One document notes that the Trisagion is “found in all the liturgies, which proves a common source and original” before the separation of East and West .
The Decisive Evidence: They Were Separate Prayers That Merged
The documents reveal a clear chronological relationship:
Phase 1 — The Kyrie Alone (c. 1st–4th century)
The earliest liturgies show only the Kyrie Eleison as the litany response. The Areopagite (Pseudo-Dionysius), writing in the late 5th or early 6th century, describes a liturgy where the Trisagion is not yet present — only “the invocations of the hierarch” followed by the congregational Kyrie Eleison .
This is consistent: the Kyrie Eleison as a congregational acclamation predates the Trisagion by centuries.
Phase 2 — The Trisagion Enters (c. 5th century)
The Trisagion appears as a separate hymn, sung during the Little Entrance (the procession with the Gospel book), not during the litany. The Gallican and Mozarabic liturgies placed it significantly as a preparation chant for the Sanctus and Benedictus — that is, it was sung as the congregation prepared to join the angels in the heavenly liturgy .
Phase 3 — Integration (c. 5th–6th century)
Here is where the relationship becomes more complex. A document describing the Syriac Liturgy of St. James — one of the oldest surviving rite texts — gives us the fully integrated sequence:
- The deacon intones: “Let us all say fervently: Lord, have mercy”
- The people respond: “Kyrie Eleison” — twelve times in some cases
- Then the congregation sings: “Holy God, holy mighty, holy immortal, have mercy upon us” — thrice
- Then: “Again and again: Let us pray to the Lord” — with further responses
In this sequence, the Kyrie Eleison functions as a litany response (to the deacon’s bidding), while the Trisagion functions as a hymn — a self-contained doxological song. They serve different liturgical roles, even when sung in immediate succession.
The Christe Eleison: The Bridge Between Them
Pope Gregory the Great’s account now becomes crucial. Writing in the 6th century, he says:
“But with us it is said by the clerks, and responded to by the people; and as often as it is said, Christe Eleison is said also, which is not said at all among the Greeks” .
The Roman rite added Christe Eleison (“Christ, have mercy”) between the repetitions of Kyrie Eleison. This creates a threefold structure:
- Kyrie Eleison — addressed to God the Father
- Christe Eleison — addressed to God the Son
- Kyrie Eleison — addressed to the Holy Spirit (or a return to the Father)
This threefold structure mirrors the Trisagion’s threefold address — Holy God, Holy Mighty, Holy Immortal — which Eastern tradition had already interpreted as addressing the three persons of the Trinity. The Roman rite effectively built the Trisagion’s Trinitarian theology into the Kyrie itself.
The Eastern church never made this adjustment. They kept the Trisagion and the Kyrie as distinct elements — one a hymn, one a litany response — and never felt the need to add Christe Eleison to the Kyrie.
So: Derivative or Simultaneous?
Neither. The evidence supports a third model:
- The Kyrie Eleison is older — by at least two centuries. It grows organically from the Gospels and the synagogue Amidah.
- The Trisagion appears later (5th century) with a claim of supernatural origin, enters as a separate hymn, and only then becomes liturgically paired with the Kyrie.
- The pairing is what’s derivative — not of each other, but of the same liturgical logic: a congregation that responds to revelation with a cry for mercy.
In the East, they remain distinct in function (litany response vs. entrance hymn). In the West, the Christe Eleison imports the Trisagion’s Trinitarian structure into the Kyrie itself — an act of theological harmonization that makes the two prayers, in a sense, say the same thing.
What’s Missing
The documents never address whether the Trisagion was consciously modeled on the Kyrie’s structure (short, repetitive, congregational, mercy-focused). The heavenly origin story would make that claim impossible in official accounts — but the structural similarity (threefold, each ending with “have mercy”) is too close to be accidental. A liturgical historian would want to know whether the Trisagion was originally a different hymn that was edited to include the mercy-petition to match the Kyrie.
Also worth noting: one document mentions that the Trisagion was sung “in the language of all the nations that were gathered” at the Council of Constantinople — implying it had a universality claim that the Kyrie (being explicitly Greek) did not. This might explain why the Trisagion spread faster in bilingual and non-Greek churches.
Dig Deeper:
- “The Trisagion’s heavenly origin story involves an earthquake at Constantinople — does this event appear in contemporary historical accounts (not just liturgical legend), and can it be dated to 447 CE or earlier?”
- “The Roman rite inserted ‘Christe Eleison’ to give the Kyrie a threefold Trinitarian form — did any Eastern liturgies ever experiment with a similar adaptation, or was the Trisagion considered sufficient for Trinitarian expression?”
- “The documents describe the Trisagion as ‘found in all the liturgies, proving a common source’ — what was that common source, and did it predate or postdate the Nicene Creed’s formulation of Trinitarian doctrine?”
