What Greek isopsephy calculates
Greek alphabetic numerals use letters as numbers. Isopsephy applies those established values to the letters in a word or phrase and compares the sum with other sums. The term ἰσόψηφος means equal in numerical value in the Liddell–Scott–Jones Greek lexicon.
A total is therefore a checkable property of a particular spelling under a declared value system. It is not, by itself, evidence that a biblical author intended a code or that two equal totals carry the same meaning.

Greek letter values used here
The system groups 27 signs into units, tens, and hundreds. The ordinary 24-letter alphabet is supplemented by the numeral signs stigma, koppa, and sampi. The Unicode Standard, Chapter 7 distinguishes those numeral characters from the historic letters digamma and archaic koppa; the calculator accepts the corresponding encoded forms where they occur.
Units · 1–9

Tens · 10–90

Counting rules
Uppercase and lowercase letters share a value. Final sigma ς equals sigma σ at 200. Spaces, punctuation, and unrecognized characters add nothing.

Why Ἰησοῦς totals 888
The exact nominative form Ἰησοῦς appears in the Greek text of Matthew 3:13. With its breathing and accent removed for the calculation, the six alphabetic characters total 888:
| Position | Greek letter | Name | Value |
|---|---|---|---|
| 1 | Ι | Iota | 10 |
| 2 | η | Eta | 8 |
| 3 | σ | Sigma | 200 |
| 4 | ο | Omicron | 70 |
| 5 | υ | Upsilon | 400 |
| 6 | ς | Final sigma | 200 |
| Total | 888 | ||
That arithmetic is reproducible for this spelling. The number does not independently establish a theological claim. Read the fuller discussion in The Name of Jesus and 888.
Language handling
Orthography comes before interpretation
Greek is inflected, so the form in a passage matters. Under the same table, nominative Ἰησοῦς totals 888, Ἰησοῦ totals 688, and accusative Ἰησοῦν totals 738. These are not competing calculations; they are different grammatical spellings. Use the form actually printed in the passage, and record the edition used.
The engine uses Unicode canonical decomposition and removes combining marks before matching base Greek letters. That makes accented and unaccented forms comparable, but it also means a subscript mark is not counted as a separate iota. The normalization rule follows the character model described in Unicode Standard Annex #15; the visible breakdown shows exactly what the calculator counted.
Transliteration is a reading aid, not the calculation text. In strict mode, Latin letters are not silently converted into Greek. Assisted mode only offers curated spellings already present in the sourced biblical-word index. For a reproducible result, paste or type the Greek form and inspect every value in the breakdown.
Text in context
Begin with what the passage is saying
Matthew 3:13 uses Ἰησοῦς while narrating Jesus coming from Galilee to John at the Jordan to be baptized. The sentence is about that action; its plain grammatical and literary meaning does not depend on the value 888. The exact Greek form can be checked in the SBL Greek New Testament text of Matthew.
A numerical observation becomes a stronger literary argument only when the surrounding composition supplies independent evidence—for example, deliberate repetition, an explicit counting instruction, or a sustained pattern that survives textual and spelling variants. Calculation should support close reading, not replace it.
Interpretation boundary
Name the confidence of each claim
High confidence
Arithmetic observation
The normalized letters of Ἰησοῦς total 888 under the displayed Greek alphabetic values. Anyone can reproduce the sum.
Conditional confidence
Literary intention
A biblical author intended readers to notice a total only when textual, compositional, or historical evidence supports that conclusion. An interesting equality alone is insufficient.
Interpretive proposal
Theological significance
Readers may explore whether a value reinforces an established biblical theme, but the proposal must remain subordinate to the passage and open to alternative explanations.
Not established
Doctrine or prediction
A shared total cannot prove identity, doctrine, divine endorsement, or a future event. Those claims require evidence beyond isopsephy.
