On Tongues of Fire
This parallel examines the motif of divine speech manifesting as or accompanied by fire across Abrahamic traditions. In Christianity, the Holy Spirit descends as cloven tongues of fire enabling glossolalia; in Judaism, the prophetic word is explicitly compared to a burning fire that consumes; in Islam, the burning bush serves as the medium for divine address to Moses. While all three utilize fire to signify the purifying and empowering nature of revelation, they diverge on whether the fire is the medium of the voice itself or a symbol of the message's potency.

What every account tells.
- iDivine communication is associated with the element of fire.
- iiFire signifies the presence and power of the deity.
- iiiThe phenomenon occurs in a context of prophetic commissioning or empowerment.
- ivThe fire does not consume the recipient in a destructive manner but rather sanctifies or empowers.
How each tradition tells it.
The fire appears as distinct 'tongues' resting upon individuals, directly enabling the physical act of speaking in other languages as a sign of universal mission. The fire is the visible manifestation of the Spirit empowering the community rather than a singular theophany to one prophet.
The text employs a simile rather than a narrative theophany, comparing the prophetic word to fire to emphasize its destructive power against falsehood and its ability to penetrate the human heart. The focus is on the nature of the message itself as a consuming force rather than a visual sign accompanying speech.
The fire is the medium of the bush itself which burns without being consumed, serving as the location where the voice of God addresses Moses directly. The emphasis is on the miracle of the bush remaining intact while serving as the vessel for the divine declaration of Lordship.
