When Jesus' followers asked about their baptism, it wasn't just a water check. It was about what that water represented.
The Apostle Paul's question, "Into what then were you baptized?" gets to the heart of what baptism signifies. It’s not merely an outward act but a profound incorporation into something new.
Embracing a New Covenant
In the ancient world, baptism was about entering a new community or covenant. When someone was "baptized unto Moses," they were pledging themselves to the Law and the covenant God made with Israel through Moses. Similarly, baptism "unto John" meant an allegiance to John’s message and mission.
Paul's Point of Departure
Paul's question highlights that their baptism into John’s message was incomplete. While John preached repentance and pointed to Jesus, his ministry ended before Jesus’ death and resurrection, and crucially, before the outpouring of the Holy Spirit in the way Jesus promised. Their baptism into John's ministry hadn't yet fully incorporated them into the new reality established by Jesus’ finished work.
