Bishops wear a miter hat remembering the tongues of fire resting on people’s heads at Pentecost (Acts 2). Some church fathers and John of Damascus described this as the baptism of fire predicted by John the Baptist in Matthew 3:1-12. That is why some churches also recognize a baptism of water on the head. If we accept that the children of Israel were baptized into Moses in a non-literal sense because they walked through dry shod, then the door is open for the word baptism to also have a non-literal meaning. Other baptisms with fire are perhaps an immersion experience. Early Christians suffered great persecution, which we call a trial by fire or baptism of fire. Also the unrepentant who choose hell over heaven will sadly be cast into a lake of fire possibly resulting in their total immersion.
