Pope Benedict XVI conducted a Mass with four sexual abuse victims this morning, but the father of two other victims said he was "disgusted" to have been sidelined from the meeting. 

Less than an hour before he was due to take off to return to Rome, the Pope officiated at the Mass at the chapel of St Mary's with a group representing victims of sexual abuse at the hands of Catholic clergy, World Youth Day organisers said. 

The four victims of sexual abuse who attended the Mass with the Pope asked to remain anonymous, Cardinal George Pell said. 

in the words of Samuel Johnson: “Where secrecy or mystery begins, vice or roguery is not far off.”
