The New Testament letters attributed to Paul depict Jesus Christ as the Son (υἱός) seventeen times. Using the phenomenon of intertextuality and typology, the present article aims to identify the Old Testament’s inspiration for Pauline use of the title “Son” for Jesus. It appears that some main archetypes of Jesus’ sonship can be recognized (Adam, Isaac, the paschal lamb replacing the firstborn son, Israel corporately as son, David, Solomon, Daniel’s Son of Man, and indirectly Isaiah’s Servant of the Lord). These pictures of sonship are intertwined by Paul and used for all main stages of Jesus’ life and activity (birth, death, resurrection, ascension and ruling, sending the Spirit and the second coming)
