Theodore and all of his 33 clones made the flaming sword vanish from their hands at once. There was only one true flaming sword that the original Theodore was carrying. So using it would be a dead giveaway.
Theodore was thinking of vanishing from there along with a few other clones. He was thinking of teleporting to different parts of the world and instantly summoning his followers and instructing them before God would find the real him.
But before doing that, God also created equal mirages of his own to fight all Theodores one on one.
Rather than fighting God though, Theodore and his clones ran around clawing the humans, tearing them apart, ripping their throats, and whatnot. He was enjoying each and every kill even though he was simply killing emotionless 'statues' right now.
