Order of 2nd and 3rd Paragraphs 

 The second paragraph presents negative arguments as to the 'validity' of the Shroud. The third paragraph presents positive arguments as to the 'validity' of the Shroud. As the significance of the Shroud owes itself to the positive arguments  its argued associated with Jesus  shouldn't those come first and the negative arguments second? From an objective standpoint it seems odd to say 'why it may not be' before 'why it may be.'
