# G3670 - homologeo

<!-- type: lexicon | created: 2026-04-26 | updated: 2026-04-26 -->

**Strong's:** [G3670](https://www.blueletterbible.org/lexicon/g3670/) · BLB lookup
**Pronunciation:** hom-ol-og-eh'-o
**Part of speech:** verb
**Etymology:** *homou* (together / same) + *logos* (word), literally "to say the same word as another"
**NT occurrences:** ~26

## Semantic range (Thayer / BDAG)

1. **To say the same thing, agree, concede**, the etymological core; to express the same statement another has made.
2. **To confess**, acknowledging what is true (whether about oneself, one's faith, or one's sin).
3. **To profess publicly**, open declaration of conviction or allegiance.
4. **To promise**, giving one's word without reservation ([Matthew 14:7](/codex/matthew-14-7/)).
5. **To praise**, by extension, public acknowledgment of God's character ([Hebrews 13:15](/codex/hebrews-13-15/) *karpon cheilōn homologountōn*).

The verb is theologically loaded because it captures **public alignment**, confession is not private belief but external alignment with what is true.

## Theological force

*Homologeō* names the **public** dimension of saving faith, distinct from but inseparable from the **internal** dimension named by [G4100 - pisteuo](/codex/g4100-pisteuo/) (believe). Pauline soteriology pairs them:

> if you confess (*homologēsēs*) with your mouth Jesus as Lord, and believe (*pisteusēs*) in your heart that God raised Him from the dead, you will be saved. ([Romans 10:9](/codex/romans-10-9/))

The combination is decisive: faith is internal trust; confession is external alignment. Both are integral to saving response, not because confession *adds* to the internal trust, but because saving faith *naturally produces* confession ([Matthew 10:32](/codex/matthew-10-32/), "everyone who confesses Me before men, I will also confess him before My Father"). A faith that refuses public confession when called to confess is suspect ([Matthew 10:33](/codex/matthew-10-33/)).

## The Romans Road context

The verse [Romans 10.13](/codex/romans-10-13/)'s "everyone who calls on the name of the Lord" is grounded in v. 9's "confess… and believe." The Romans Road structure:

1. [Romans 3.23](/codex/romans-3-23/), universal sin
2. [Romans 6.23](/codex/romans-6-23/), wages of sin / gift of God
3. [Romans 5.8](/codex/romans-5-8/), God's love demonstrated
4. **[Romans 10.9](/codex/romans-10-9/)**, *homologēsēs* + *pisteusēs* = saved
5. [Romans 10.13](/codex/romans-10-13/), universal scope

The fourth step is *homologeō*, the personal-confessional response.

## Patristic / scholarly note

The early creeds, Apostles' Creed, Nicene Creed, are formal *homologiai* (confessions). The credal tradition is the church's structured response to "what shall we confess?" Tertullian (*Prescription Against Heretics* 13, c. AD 200) and Irenaeus (*Against Heresies* I.10) appeal to the *regula fidei*, the rule of faith, as the church's earliest *homologia*.

The Reformation pressed *confessing* as integral to faith, Luther's *Heidelberg Disputation* (1518) and Calvin's *Institutes* IV (the church and sacraments) develop confession as the *external mark* of true faith. The Reformed *confessions* (Belgic, Heidelberg, Westminster, etc.) are formal *homologiai* in this tradition.

Modern evangelical: J. I. Packer (*Knowing God*); Tim Keller (*Center Church*), confession as the public dimension of faith; baptism and the Lord's Supper as embodied *homologia*.
