Days after Catholic Memorial High School students chanted "You killed Jesus" during a weekend basketball game at Newton North High School, the Archdiocese of Boston called the students' behavior "unacceptable."

"The Archdiocese wishes to make clear that the behavior of a number of students from Catholic Memorial at the game is unacceptable," The archdiocese said in a statement.   

The archdiocese said it was "pleased" that Catholic Memorial's administration's response.

"We are pleased that the administration of Catholic Memorial took corrective action immediately during and after the basketball game," O'Malley said. "This incident, while not representative of the school community, presents an opportunity to promote an important learning experience for the students."

Meanwhile, some Catholic Memorial students have been asked not to attend a semifinal basketball.

The Boston Globe reports administrators for Catholic Memorial, in the city's West Roxbury neighborhood, asked the students not to attend Monday night's semifinal game. They issued a statement calling the chants "appalling" and announcing a series of student assemblies about them.

Catholic Memorial students attending Friday's game against Newton North High School—Newton has a large Jewish population—yelled the chant in response to taunts about the all-boys Catholic school not having any female students.

Catholic Memorial President Peter Folan apologized for what he called "abhorrent behavior."

Newton Public Schools Superintendent David Fleishman says he contacted the Anti-Defamation League.

The Archdiocese of Boston has learned of a troubling incident that occurred on Friday evening at Newton South High School, during a basketball game between Newton North and Catholic Memorial High Schools. The Archdiocese wishes to make clear that the behavior of a number of students from Catholic Memorial at the game is unacceptable.   

On Thursday evening of this past week, in observance of the 50th anniversary of the Church’s landmark document that overturned the Church’s history of anti-Jewish attitudes and teaching, Cardinal Sean O’Malley stood in solidarity with hundreds of members of the Jewish community and in affirming the Jewish and Catholic communities’ shared heritage of faith.

We are pleased that the administration of Catholic Memorial took corrective action immediately during and after the basketball game. This incident, while not representative of the school community, presents an opportunity to promote an important learning experience for the students.

We stand ready to assist Catholic Memorial in providing the student body with the awareness education that is needed to ensure that there is no recurrence of these actions or attitudes.”
