Strong’s G5206: A compound of υἱός (son) and θέσις (placing); the formal act of adopting someone as a son with full legal rights and privileges. In NT usage, describes believers’ adoption into God’s family through the Messiah, granting full rights as heirs.

U- Unveiling the Word

The term υἱοθεσία carries profound theological significance, representing far more than mere acceptance into a family. In Greco-Roman culture, adoption was a formal legal process that granted the adopted person full rights and privileges of natural-born children, often used by emperors to secure succession. Paul employs this cultural understanding to explain believers’ relationship with God, emphasizing our complete transformation from slaves to sons through the Messiah. Early church fathers extensively used this term to emphasize the remarkable privilege of Christian adoption, highlighting the contrast between our former state and our new status as God’s children. Today, this word continues to remind us of our incredible privilege and position as fully accepted members of God’s family.
