A good day (like most days) for Eucharistic Adoration (updated)

As the Boston Globe reports, here, today, "the Harvard Extension Cultural Studies Club plans to host a reenactment of a historical 'black mass,' which is believed to mock traditional Roman Catholic rituals."  ("Which is believed"?).  At the same time, "the Roman Catholic Archdiocese of Boston will host a eucharistic procession from MIT to a nearby church for an hour of prayer, hoping to 'combat evil' with positive worship, church officials said."  

UPDATE:  At the last minute, the "black mass" was cancelled.  And, according to reports I've read and pictures I've seen (here, for example) the Eucharistic Adoration was moving . . . and jam-packed.
