I have already answered this, but again:<quoted text>
Quite simply - In Leviticus 14 does the Bible make any kind of statement about any cure for leprosy? Does this stated cure work?
Your premise is false.
You assume that the instructions are universal and absolute in all instances of leprosy.
You also have no knowledge of the levitical laws being prophetic, so you cannot comprehend what they are actually representative of, on the prophetic and symbolic level.
But that is ok, because it is not for you anyway, unless you repent of your secular suppression of God.
Hence your confusion.
