I don't recall much about Eternal Law, but that statement addresses what I've suspected it refers to. The "Gods all the way back" version of theology unique to Mormons.
The very best Mormons can become Gods and Goddesses in the afterlife. But although they are now Gods, our God, Yahweh, is still above them. Just as Yahweh's God is above him. So although Yahweh is a god, he's still bound by the rules that his god imposed, who is subject to the laws his god imposed, ad infinitum.
Here's a link to a BYU page about Law and Eternal Law. I couldn't be arsed to do more than skim it, having long since had my fill of their silliness, but it might clear up a few things that Janadele seems unwilling to address.
Can you explain how that jells with the clear monotheistic message that Janadele quoted earlier: “For there is one God, and one mediator between God and men, the man Christ Jesus” (1 Timothy 2:5)?
