Because in this world exist people that existed before the church and can immediately call them out when doing shit.
There exist people that are old enough to have known the goddess or might actually be the human form of her.
You actually have an empire that has reached the state of religious fanatism in their idol cult.
Rewrote history to ground their founding with the progenitor of humanities magic, but turn the women in question into a men to suit their narrative and knowingly promote that lie.
They turned the hero Himmel into a solo fighter bearing the uniform of their empire.
They have a secret kill squad that has placed sleeper agents for decades all over the continent to assassinate people that can proof that their narrative is wrong.
Worse the elves can proof the hero is actually an orphan from the southern kingdoms, the same elf is actually the true disciple of the founder of humanities magic and even worse another elf is the teacher of that founder and even the reason she could reach that point.
