Can Godelian Self-Reference Prove its Own Truthfulness?

[agapito]

Please consider this, supposedly Godel’s creation:

The result of substituting the quotation of “The result of substituting the quotation of x for ‘x’ in x has property P.” for ‘x’ in “The result of substituting the quotation of x for ‘x’ in x has property P.” has property P.

Supposedly this ends up in a sentence that “says of itself it has Property P” in the sense that it says that a sentence satisfying a certain description has property P, and the sentence itself is the only one and only sentence satisfying that description

Can anyone make sense of this convoluted language? All help appreciated

.Essentially, this sentence is saying that if you take the original sentence ("The result of substituting the quotation of x for 'x' in x has property P.") and replace the word 'x' with the quotation of that same sentence, the resulting sentence still has property P. In other words, the sentence is self-referential and can be used to prove its own truthfulness.
