υἱός
a son, descendent
Definition
The Greek word υἱός primarily means 'son' in a biological sense, as seen in references to Jesus as the son of Joseph (Matthew 1:25) or David as the son of Jesse. It also extends to denote descendants, such as 'sons of Abraham' meaning his offspring (Galatians 3:7). Importantly, in the New Testament, it carries a theological sense of relationship, especially in titles like 'Son of God,' which signifies Jesus' unique divine nature and intimate connection with the Father (Matthew 3:17). Additionally, it can imply membership in a group, as in 'sons of the kingdom' (Matthew 8:12) or 'sons of disobedience' (Ephesians 2:2), indicating shared characteristics or destiny.
Biblical Usage
υἱός is used frequently throughout the New Testament, with high concentration in the Gospels and Pauline epistles. It often appears in genealogies (Matthew 1:1-16), narratives about family (Luke 15:11-32), and theological discourses on Jesus' identity (John 3:16-18). A key pattern is its use in titular phrases like 'Son of Man' (Mark 2:10) and 'Son of God' (Romans 1:4), which are central to Christology. It also metaphorically describes believers as 'sons' in a relational sense through adoption (Galatians 4:5-7).
Etymology
Derived from Proto-Indo-European *suHnús, meaning 'son,' it is cognate with Sanskrit 'sūnú' and English 'son.' In Greek, υἱός is the standard term for a male child and retained this core meaning into Koine Greek, though it expanded in biblical usage to include metaphorical and theological dimensions of relationship and affiliation.
Semantic Range
υἱός is theologically crucial as it underpins the doctrine of Christ's divinity and sonship. Jesus' title 'Son of God' affirms His unique relationship with the Father and role in salvation (John 20:31). Understanding this Greek term enriches Bible reading by clarifying that 'son' often conveys essence and authority, not just descent, as when Jesus is called 'the Son' in Trinitarian contexts (Hebrews 1:2). It also highlights believers' adopted status as children of God (Romans 8:14-17). In first-century Jewish and Greco-Roman culture, 'son' implied legal inheritance, family identity, and carrying on the father's legacy. Unlike modern individualism, sonship denoted embeddedness in a household with obligations and privileges. This context illuminates passages where Jesus is called 'son of David' (Matthew 1:1), stressing messianic lineage, or where believers become 'sons' through adoption into God's family (Galatians 4:5-7), gaining full rights as heirs. τέκνον (teknon, G5043) — emphasizes childlike relationship or offspring, often used for believers as 'children of God'; παῖς (pais, G3816) — can mean 'child' or 'servant,' sometimes used for Jesus as 'servant' (Acts 3:13); μονογενής (monogenēs, G3439) — means 'only begotten,' highlighting uniqueness, as in John 3:16 for Jesus.
