Let it go.
You have not been tasked with trouncing Jedediah.
God is over him and well able to conform him to the image of His Son . . . as Jedediah has repeatedly asked Him to do.
I don’t see you adding anything constructive to that project.
I have been tasked with exposing false prophets. I was delivered from a cult that had plenty of them. And generally they used better grammar than Jedediah.
