Harvard Extension Cultural Studies Club released a statement, and confirmed that no consecrated host will be used.

"While a piece of bread is used in the reenactment, the performance unequivocally does not include a consecrated host. Our purpose is not to denigrate any religion or faith, which would be repugnant to our educational purposes, but instead to learn and experience the history of different cultural practices," the club said.

Harvard Extension School affirmed the right of students and student clubs on campus to exercise freedom of expression, even in such cases.

"Harvard Extension School does not endorse the views or activities of any independent student organization. But we do support the rights of our students and faculty to speak and assemble freely," the school said.

The Archdiocese of Boston released the following statement May 7:

STATEMENT OF THE ARCHDIOCESE OF BOSTON REGARDING BLACK MASS AT HARVARD

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 naïve 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.
