No doubt you’ve heard about the sold-out, international “SatanCon” that took place in Boston over the weekend of April 28-30.

A Harvard-affiliated student club will host a Satanic “black Mass” May 12 as part of an educational exercise, a stunt that the Archdiocese of Boston says “places participants dangerously close to destructive works of evil.”
