Father-Host: Science Fiction

They ate their father-host before they knew him. Before they knew themselves. Before they were themselves. It is only with the consumption of the host that they could take knowledge, understand forgiveness, realize the depth of their transgression, and how much their father-host had forgiven them. He knew. He knew that they would eat him and kill him, quite painfully, and that it was the only (only?) way they could be born. He had--they found out, as mandibles chewed through the brain stem, as the meat writhed around them and screams filled the air--he had been able to kill them, if he wanted. He had chosen not to, despite knowing it would be his death (and salvation? they were confused by that part, as they were confused by so much). They were nearly full, the host-father being larger than--than the herd animals that were traditional, and how had they known that? Still, the little bits of knowledge they ate made the whole more urgent, and they arrowed into the braincase, jaws gnashing, as around them the meat-host-father convulsed one last time and lay still, the electrical impulses dying.

Inspiration: I haven't done anything organic/creepy/gritty in a while, and I miss it.
Story Potential: High
Notes: And then they make their way in the world. A world that has barely survived the battle to exterminate their kind? The power of the willing sacrifice, etc. Be subtle with the religious metaphors.
