Just how picky do you think El is about who joins him in Heaven?! Granted Calvinism has its own pickiness problems (just look at Vincent Cheung), but that’s probably not the issue you have.
The Bible, KJV or otherwise, isn’t the good-guy equivalent (or any other equivalent) of The King in Yellow, anyway.
Honestly, if El is so terrified of his holiness being compromised, why did he bother creating anything, even Jesus and Lucifer, to begin with?
