βαπτίζω

The Greek verb *baptizō* literally means to immerse, submerge, or to make fully wet. It carries the core idea of being overwhelmed or covered by a fluid. While in classical Greek it could refer to drowning or dipping, its primary usage in the New Testament is highly specialized, referring almost exclusively to ritual washing or Christian baptism. This technical usage shifts its semantic range from merely a physical action to a deeply symbolic and theological one.

In the New Testament, *baptizō* is most frequently associated with John the Baptist and the sacrament of Christian baptism. John’s baptism was a baptism of repentance for the forgiveness of sins, preparing the way for Jesus. Christian baptism, instituted by Christ, signifies a believer’s identification with Christ’s death, burial, and resurrection, and is a public declaration of faith. It symbolizes the washing away of sins and the inward work of the Holy Spirit.

The theological weight of *baptizō* is significant. It describes not just an outward washing, but an inward spiritual transformation and a new covenant relationship with God. While other Greek words exist for washing (e.g., *louō* for bathing the whole body, *niptō* for washing parts of the body), *baptizō* is chosen to convey the specific, covenantal act. The concept of being "baptized into Christ" (Rom 6:3) points to a profound union with Him, sharing in His redemptive work.
