The Archdiocese of Boston has released the following statement:
The Catholic community in the Archdiocese of Boston expresses its deep sadness and strong opposition to the plan to stage a "black mass" on the campus of Harvard University in Cambridge. For the good of the Catholic faithful and all people, the Church provides clear teaching concerning Satanic worship. This activity separates people from God and the human community, it is contrary to charity and goodness, and it places participants dangerously close to destructive works of evil.
In a recent statement, Pope Francis warned of the danger of being naive about or underestimating the power of Satan, whose evil is too often tragically present in our midst. We call upon all believers and people of good will to join us in prayer for those who are involved in this event, that they may come to appreciate the gravity of their actions, and in asking Harvard to disassociate itself from this activity.
The following events are taking place this evening at the same time as the "black mass" planned by the group at Harvard:
Campus Ministry of the Archdiocese of Boston
Monday, May 12 at 7 pm for Exposition and Adoration at the MIT chapel (corner of Mass Ave and Amherst Street). A Eucharistic procession will leave the chapel at approximately 7:15 pm and process up Mass Ave to St. Paul Church in Cambridge.
