Blood, saint’s image, and ashes form the invariant mafia oath core

Evidence

Several of the accounts fail to report the words of the oath, and some sources claim not to remember them. Still, an invariable essence is clearly identifiable. The blood, the image of the saint, their mingling and reduction to ashes: these are unfailingly present in all descriptions and represent the stable symbolic configuration of the ritual. — Diego Gambetta, The Sicilian Mafia The Business of…, 383

Categorization

• DEFINE: Defines the stable symbolic core of the initiation ritual, separating invariant elements from regional variations.
