Identity: Jude identifies himself as "a servant of Jesus Christ and brother of James" (Jude 1). He is commonly understood to be Judas (not Iscariot), one of the half-brothers of Jesus mentioned in the Gospels (Matthew 13:55; Mark 6:3).
Background: As a member of Jesus' earthly family, Jude likely did not believe in Jesus during His earthly ministry (John 7:5) but became a believer after the resurrection. His brother James became the leader of the Jerusalem church.
Humility: Despite his relationship to Jesus, Jude humbly calls himself a "servant" rather than claiming his physical kinship with the Lord, demonstrating spiritual maturity and proper perspective.
Knowledge of Scripture: Jude shows extensive knowledge of Old Testament accounts and Jewish literature, referencing multiple historical examples and possibly quoting from the Book of Enoch.
Date: Written approximately AD 66, likely in the latter part of the apostolic age.
Audience: Written to Jewish Christians, likely in Palestine or Syria, who were familiar with Old Testament history and Jewish traditions.
Setting: The early church was facing increasing challenges from false teachers who were twisting grace into licentiousness and denying Christ's authority.
Reason for Writing: Jude had intended to write about the common salvation but felt compelled by the Holy Spirit to instead issue an urgent warning about false teachers who had secretly infiltrated the church. These individuals were perverting the grace of God into a license for immorality and denying Jesus Christ. Jude wrote to exhort believers to "contend earnestly for the faith" that had been delivered to the saints.
Relationship to 2 Peter: Jude shares significant similarities with 2 Peter 2, suggesting either common source material or that one author was familiar with the other's work.
"Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints."
— Jude 3 (NKJV)
