Baptism, then, is not what produces salvation; it is an oath of loyalty to the risen Savior, a public avowal of who is on the Lord’s side in the cosmic war between good and evil. It is also a visceral reminder to the defeated fallen angels.
Every baptism is a reiteration of their doom in the wake of the gospel and the kingdom of God.
Early Christians understood the typology of this passage and its link back to the fallen angels of Genesis 6. Early baptismal formulas included a renunciation of Satan and his angels for this very reason.
Baptism was and is spiritual warfare.
