STRONGS NT 947: βδελυκτός

βδελυκτός, βδελυκτη, ὄν (βδελύσσομαι), abominable, detestable: Titus 1:16. (Besides only in Proverbs 17:15; Sir. 41:5; 2 Macc. 1:27; (cf. Philo de victim. offer. § 12 under the end).)

Topical Lexicon
Essential Idea

βδελυκτός expresses moral repugnance before a holy God. It describes persons or deeds that are not merely wrong but revolting—objects of divine loathing that must be rejected unless cleansed by grace. Though the term occurs only once in the Greek New Testament, it gathers up a rich Old Testament heritage and supplies a forceful verdict on counterfeit Christianity.

New Testament Usage

Titus 1:16 introduces the word in a context of church oversight on Crete. False teachers claimed saving knowledge yet lived in contradiction to that claim. Paul writes, “They profess to know God, but by their actions they deny Him. They are detestable, disobedient, and unfit for any good deed” (Titus 1:16). Three charges escalate in severity: the sham is first judged abominable (βδελυκτοί), then rebellious, then useless. The Holy Spirit thus brands hypocrisy itself as something God cannot endure within His household.

Old Testament Background

1. Moral abominations. The Septuagint frequently uses cognates of βδελυκτός for practices that violate the covenant—idolatry (Deuteronomy 27:15), occult involvement (Deuteronomy 18:12), sexual perversion (Leviticus 18:22), and dishonest commerce (Proverbs 11:1).
2. Cultic impurity. Objects dedicated to false gods become “detestable things” that must not enter the sanctuary (Deuteronomy 7:26).
3. Nations under judgment. Canaanite sins are said to be so detestable that the land “vomits out its inhabitants” (Leviticus 18:25), illustrating how communal sin invokes divine wrath.

Relationship to Other Greek Terms

• βδέλυγμα (Strong’s 946) points to the result—“abomination” normally connected to idolatry (Matthew 24:15; Revelation 17:4).
• βδελύσσομαι (to feel disgust) describes the reaction of conscience or of God Himself (Romans 2:22).

βδελυκτός, by contrast, labels the person or thing that provokes such revulsion.

Theological Implications

1. God’s holiness is not abstract; it includes moral sensitivities that find evil revolting (Habakkuk 1:13).
2. Hypocrisy is as loathsome as overt idolatry. By placing βδελυκτός alongside “disobedient” and “unfit,” Titus 1:16 teaches that a life divorced from professed faith insults God as surely as pagan worship.
3. Redemption in Christ answers the verdict. The detestable can become “sanctified, useful to the Master, and prepared for every good work” (2 Timothy 2:21) when cleansed by His blood (Hebrews 9:14).

Historical and Cultural Setting

In Greco-Roman society certain foods, diseases, and social practices were labeled miara (polluted), reflecting a worldview that feared contamination. Paul leverages that shared sense of disgust but grounds it in revelation: the defilement that truly matters is ethical, not ceremonial. By branding false teachers βδελυκτοί, he strikes at their honor-shame standing, warning the churches that such men are spiritually toxic.

Pastoral and Ministry Significance

• Discernment for elders. The wider passage (Titus 1:10-16) instructs overseers to silence deceptive voices. Recognizing what God calls detestable safeguards the flock.
• Church discipline. A profession of faith without consonant works must eventually face corrective action for the sake of purity (Matthew 18:15-17; 1 Corinthians 5:11-13).
• Gospel invitation. Labeling sin as detestable does not close the door; it magnifies the mercy offered in Christ, who “gave Himself for us to redeem us from all lawlessness and to purify for Himself a people for His own possession, zealous for good deeds” (Titus 2:14).

Homiletical and Discipleship Insights

1. Expose counterfeit faith. Use Titus 1:16 to contrast appearance with reality and to call believers to integrated living (James 1:22).
2. Highlight God’s emotional response to sin, moving beyond legal categories to relational offense.
3. Celebrate transforming grace: those once detestable become vessels of honor through repentance and faith (1 Peter 1:14-16).

Summary

βδελυκτός concentrates Scripture’s abhorrence of hypocrisy, idolatry, and moral corruption into a single, potent adjective. Its lone New Testament appearance pierces the veneer of empty religion and summons the church to authentic godliness secured by the cleansing work of Jesus Christ.
