== Extraordinary form of the Roman Rite == 

 The claim has been made in an edit summary that there is only one extraordinary form of the Roman Rite.  There are many, but only one of them is authorized, the 1962 form.  Pope Benedict XVI stated that the 1962 edition of the Roman Missal was never juridically abrogated.  Nor were the pre-1962 editions juridically abrogated.  Some are regularly used by those who reject Pope John XXIII and his 1962 Missal, not to speak of those who reject even Pius XII's alterations of the Triduum Sacrum texts.  Celebration of Mass with any pre-1970 edition is a form of Mass of the Roman Rite, an extraordinary form of it, whether it is authorized or non-authorized.  Since there are several, it is inexact to speak of any one of them as the one and only extraordinary form - except when clearly speaking of the two authorized forms of the Roman Rite, in which case one can certainly refer to "the" extraordinary one.  But not outside of that context.
