Need help translating weird sentence

This is in a book I'm reading:

Requiescat In Constantia, Ergo, Repraesentatio Cupidi Auctoris Religionis

Google translate says it means:

"May he rest in Constance, Therefore, Eager for the author's representation of religion."

Which sounds like Engrish to me, the meaning isn't getting through. Can anyone help?

Thanks,

Something close to "may he always wait, never knowing the author's opinion on religion" I think?
