Topical Lexicon Domain of Meaning Strong’s Greek 3921 depicts a stealthy entrance into a community, the taking of a place that was neither invited nor observed. In Jude 1:4 the verb portrays false teachers slipping into the fellowship undetected, indicating secrecy, craft, and intent to alter the congregation from within. Canonical Context Jude writes as one who “was compelled to write and urge you to contend earnestly for the faith” (Jude 1:3), and immediately exposes the danger: “For certain men have crept in among you unnoticed” (Jude 1:4). The single use of 3921 stands at the hinge between the epistle’s call to vigilance and its catalog of judgment on error. Everything that follows—moral license, denial of Christ, examples of apostate angels, Sodom and Gomorrah, Cain, Balaam, Korah—unfolds as evidence of what clandestine entrance can unleash when unchallenged. Theological Themes 1. Spiritual Subterfuge. 3921 underscores that the threat to the church is often internal, not overt persecution but quiet distortion (Matthew 24:24; 2 Peter 2:1). Historical Background First-century congregations faced traveling teachers who blended early Gnostic ideas, antinomian practice, or Jewish legalism with apostolic preaching. Comparable infiltration troubled the churches of Galatia: “false brothers were brought in secretly” (Galatians 2:4). By the late first century, itinerant charlatans could exploit hospitality networks, prompting Jude and John (3 John 1:9-10) to set tests for authentic teaching.

Application for Contemporary Ministry • Review teaching platforms—conferences, online content, small-group curricula—for unvetted voices. Summary Strong’s 3921 encapsulates the covert arrival of influences that oppose the gospel. Jude’s lone use of the verb becomes a clarion call across the ages: guard the entrusted faith, for threats usually enter softly before they speak loudly.
