|“||You know that if you had possessed the Flaming Sword, the weapon that guarded Eden, the weapon that can cut through anything, even the Gates of Heaven itself, well, you would've won that rebellion.||„|
|— Goddess to Lucifer Morningstar|
in "Candy Morningstar"
The Flaming Sword is a phenomenally powerful divine weapon. God split the sword into three pieces during Lucifer Morningstar's rebellion. The Flaming Sword is the most powerful weapon in the Universe. The Flaming Sword is a divine weapon, powerful enough that it can eradicate any being in the Universe, including Gods (at least while they are in a weakened state). The weapon has the power to cut through virtually anything, including, as proven by Lucifer, the fabric of reality.
The primary component of the sword is the Blade of Death, also known as Azrael's Blade. Much like its name suggests, it is a weapon wielded by Azrael, the Angel of Death, and is capable of eradication on its own. Another piece, the Medallion of Life, was left on Earth and is capable of [[healing while also granting divine knowledge to the wearer. The third piece, The Key, generally known as Amenadiel's necklace, binds the parts together. It was left in the possession of 'God's Favorite Son', which is later shown to be Amenadiel. The necklace is capable of lending its strength to whoever holds it, even making it possible for Humans to overpower Angels if they are in possession of it. When Azrael's Blade is not on Earth, the other two pieces remain inactive.
When all of the pieces are combined, the sword's flames will extend to the size and shape of an entire sword's length.
The Flaming Sword is also a known weapon in the Hebrew and Christian Bibles.
The Flaming Sword is the weapon that guarded Eden. However, during Lucifer Morningstar's rebellion, God split the sword into three pieces, thinking that Lucifer would use it against him. Most, including Lucifer, believed the weapon to be destroyed.
Throughout the Series
In "The Good, the Bad and the Crispy", Lucifer assembled all of the pieces and the Flaming Sword revealed its true form as a large sword of fire. Lucifer refused to use the sword to return Goddess to Heaven as war would break out and many Angels would die. Instead, Lucifer used the sword to open a tear in the universe into a Void and asked Goddess to go through and create a new universe for herself. He says to her, "going home, that's not starting over that's going backwards. And that's not good for anyone. So it's time for you to move forward." Not wanting the death that would come from the war, Goddess left Charlotte Richards's body and went through the tear. Lucifer then removed the Key from the sword and tossed its other pieces through the tear into the void before the rift closed.
In "Nothing Lasts Forever", Gabriel steals Azrael's Blade and the Medallion of Life from Goddess' new Universe while delivering a message to her on Lucifer's behalf. Gabriel subsequently delivers the two pieces of the Flaming Sword to Michael.
In "Is This Really How It's Going To End?!", Michael hires French mercenaries to hunt for the Key which was stolen from Caleb Mayfield's body and ended up in the hands of a man named TJ Ross. Daniel Espinoza investigates the case, leading to his murder at the hands of the mercenaries. Lucifer and Amenadiel subsequently put together what happened to the Key and that Michael is attempting to reassemble the Flaming Sword to win a war instead of an election.
In "A Chance at a Happy Ending", Michael finishes assembling the sword after retrieving the Key. During his fight with Lucifer, Michael wields the Flaming Sword while Lucifer uses Zadkiel's staff made out of the Tree of Life with which he manages to counter the Sword for a while before it finally broke. Eventually, Lucifer and Chloe Decker manage to separate the Blade and the key, but Michael kills Chloe.
After Lucifer resurrects her and Chloe defeated Michael using the strength the Key gave her, Michael accepts what he believes to be his execution only to have Lucifer use the Flaming Sword to severe his wings instead. After the other Angels kneel before him as the new deity, Lucifer raises the Flaming Sword into the air and mutters "oh my Me."
In "Nothing Ever Changes Around Here", it's revealed that Lucifer keeps the pieces of the Flaming Sword in his safe aside from Amenadiel's necklace which Chloe has removed and continues to use.
- Dimensional Slicing: The Sword can cut through time and space, creating a portal to a Universe-sized void.
- Absolute Sharpness: When complete, it's said to be able to cut through anything, even the Gates of Heaven, and was seen to be able to cut through the very fabric of space.
- Absolute Immunity: Whoever is armed with this sword is immune to all the powers, even the power of God or the Goddess. It's this power that forced God to divide the sword into three parts after Lucifer's rebellion, because if Lucifer had had it at that time, he would have won.
