This file photo taken on April 2, 2015 shows Australian Cardinal George Pell, Prefect of the Secretariat for the Economy of the Holy See arriving to attend a Chrism mass for Holy Thursday (Maundy Thursday) which marks the start of Easter celebrations at St Peter's basilica in Vatican. Pell on June 1, summoned his lawyers after Pope Francis' specially-appointed commissioner for the protection of children accused him of being "almost sociopathic" and said his position was untenable. Formerly the top Catholic cleric in Australia, Cardinal Pell is embroiled in a child abuse inquiry in his homeland which last week heard evidence from the nation's worst paedophile priest Gerald Ridsdale.
