You're missing my point. Unless you are claiming that there is a 
difference between 'x if and only if y' and 'x is true if and only if y 
is true', then there is no reason for such a predicate at all. The fact 
that you insist on including it suggests you *do* think there is a 
difference in meaning between these two examples. So what is that 
difference?

But whatever it means, LP ↔ ¬True(LP) is either simply true or simply 
false. It is *not* the liar paradox. Most likely it is simply false 
since I assume LP ↔ ¬True(LP) is simply the same as LP ↔ ¬LP.

If you want to paraphrase Gödel, you need both G and ⌈G⌉ to be present 
in your statement.
