STRONGS NT 5198: ὑγιαίνω

ὑγιαίνω; (ὑγιής); from Herodotus down; to be sound, to be well, to be in good health: properly, Luke 5:31; Luke 7:10; Luke 15:27; (3 John 1:2); metaphorically, the phrase ὑγιαίνειν ἐν τῇ πίστει (Buttmann, § 133, 19) is used of one whose Christian opinions are free from any admixture of error, Titus 1:13; τῇ πίστει, τῇ ἀγάπη, τῇ ὑπομονή, (cf. Buttmann, as above), of one who keeps these graces sound and strong, Titus 2:2; ὑγιαίνουσα διδασκαλία, the sound i. e. true and incorrupt doctrine, 1 Timothy 1:10; 2 Timothy 4:3; Titus 1:9; Titus 2:1; also λόγοι ὑγιαίνοντες (Philo de Abrah. § 38), 1 Timothy 6:3; 2 Timothy 1:13, (ὑγιαινουσαι περί θεῶν δόξαι καί ἀληθεῖς, Plutarch, de aud. poet. c. 4).

Topical Lexicon
Definition and Semantic Range

Strong’s Greek 5198 (ὑγιαίνω, hygiainō) moves along two complementary planes: literal bodily wellness and figurative doctrinal soundness. In classical Greek it denoted physical health; in the New Testament the Spirit broadens the term to embrace spiritual integrity, moral wholeness, and purity of teaching. Thus the same verb that describes a healed servant in Luke also characterizes apostolic doctrine in the Pastoral Epistles.

Occurrences and Categories

Twelve inspired uses fall naturally into two groups:

• Physical health: Luke 5:31; 7:10; 15:27
• Spiritual soundness: 3 John 1:2; 1 Timothy 1:10; 6:3; 2 Timothy 1:13; 4:3; Titus 1:9, 1:13; 2:1; 2:2

Physical Health and Christ’s Compassion

Luke 7:10 records, “When those who had been sent returned to the house, they found the servant in good health.” Here ὑγιαίνω testifies to Christ’s sovereign authority over disease. In Luke 5:31 Jesus says, “It is not the healthy who need a doctor, but the sick,” framing His messianic mission in medical imagery that anticipates the cross. Luke 15:27 rejoices that the prodigal is “safe and sound,” underscoring that repentance restores wholeness. These passages root the term in tangible mercy, showing that the gospel addresses body as well as soul.

Sound Doctrine in the Pastoral Epistles

Paul employs ὑγιαίνω eight times in First and 2 Timothy and Titus. The emphasis is unmistakable: teaching must be free of infection from error.

• “Hold firmly to the trustworthy word… so that he can encourage others by sound doctrine” (Titus 1:9).
• “Rebuke them sternly, so that they will be sound in the faith” (Titus 1:13).
• “Older men are to be… sound in faith, in love, and in perseverance” (Titus 2:2).
• “For the time will come when men will not tolerate sound doctrine” (2 Timothy 4:3).

Sound doctrine protects the flock from heresy just as health safeguards the body from disease. Paul’s physician-like language fits a missionary pastor writing to younger co-workers tasked with protecting embryonic congregations.

The Prayer of the Elder Apostle

John echoes the same duality in 3 John 1:2: “Beloved, I pray that in every way you may prosper and enjoy good health, as your soul also prospers.” Physical and spiritual well-being walk hand in hand; neither is neglected in apostolic care.

Historical Background

Greek medical literature used ὑγιαίνω for bodily health, often contrasted with νόσος (disease). Early Christians respected this background while infusing the word with redemptive significance. The Great Physician not only cures fevers (Luke 4:39) but delivers from sin’s corruption. By the second century, church fathers such as Irenaeus defended “sound” apostolic teaching against the “sickness” of Gnosticism, retaining the Pauline metaphor.

Theological Significance

1. Wholeness: Salvation restores total personhood.
2. Purity: Truth is not merely correct data but life-giving medicine.
3. Perseverance: Health must be maintained; doctrine must be guarded.
4. Community: A congregation thrives when every member and every teaching is ὑγιαίνω.

Practical Ministry Application

• Preachers—diagnose doctrinal drift early; prescribe Scripture.
• Elders—model healthy faith, love, perseverance (Titus 2:2).
• Believers—submit to the Great Physician daily; embrace both physical stewardship and theological discipline.
• Corporate worship—reinforce sound words (1 Timothy 6:3) through Scripture-saturated liturgy and hymnody.

Connections with Other Biblical Themes

Healing (ἰάομαι), salvation (σῴζω), and cleansing (καθαρίζω) converge with ὑγιαίνω. The gospel does not merely remove guilt; it renews life. This integrative vision combats the false dichotomy between creed and conduct.

Patristic and Later Reception

From the Nicene Creed’s insistence on “true God” to the Reformation’s sola Scriptura, the church has pursued doctrinal health. The term shapes confessional language—“the pure preaching of the gospel” (Belgic Confession)—and informs pastoral qualifications in historic polity.

Summary

ὑγιαίνω unites the spheres of physical restoration and theological fidelity. Christ heals bodies in the Gospels; Paul and John call for healthy doctrine and souls in the Epistles. The church today honors this inspired word by caring for human need and guarding Scriptural truth, that both body and belief may remain “safe and sound” to the glory of God.
