"Michael O’Neill, 39, a Stanford University graduate in mechanical engineering and product design, is the Virgin Mary’s big data numbers cruncher. On his website, MiracleHunter.com, he has codified every known apparition of Mary back to A.D. 40. Systematic investigation and documentation of supernatural occurrences began with the Council of Trent, the Catholic Church’s ecumenical reaction to the Reformation, more than 450 years ago. Of the 2,000 apparitions reported since then, Miracle Hunter cites a mere 28 as approved by local bishops, who are the first to decide whether “seers” seem plausible. Sixteen of those have been recognized by the Vatican."
