Satan is always a counterfeit, always a re-actor.
He gets his ideas from God’s Word and perverts them in order to mock people who believe in Mormonism or whatever other extra-biblical cult they belong to.
Remember, it is all about Satan telling Mormons that under garments are part of salvation and then mocking the Mormons for wearing them - in the messianic age of grace.
It’s a ploy to deprive them of understanding who Jesus actually is, and why He died on the cross for our sins.
An even BIGGER lie is about the nature; and BODY; of the Father!
