According to the Ealing Today website, Father David Pearce and John Maestri have both been charged with child abuse offences dating from the late 1970s. Although the report doesn't specifically say so, it would appear that the victim or victims of these alleged offences are pupils of St. Benedict's, since both were teachers at St. Benedict's at the time.
Mr. Cleugh and Mr. Simmons (the senior and junior school headmasters) have written to parents. Their letter has included the following. "We ask for your prayers for all affected by these latest allegations and for the School at this difficult time.''
Now that is a very odd thing to say. They asking for your prayers for those affected by the allegations. That means thay are asking for your prayers primarily for Pearce and Maestri themselves, as they are most affected by the allegations. And then they are asking for prayers for the school "at this difficult time". There is no suggestion that you should pray for the victims of the alleged crimes.
