Remember that letter sent by an anoymous group of 26 clergy (who had all the earmarks of being classically heterodox) to several people in the diocese of Altoona-Johnstown, Pennsylvania? There was some doubt as to whether the letter was real or whether it was a put-up job by someone trying to incite an internecine war in the diocese. Well, the police are treating a follow-up letter as all too real.
