Some are being investigated for sexual abuse while others are accused of failing to report it.The archbishop read out a letter from Cardinal Ricard, who said he had behaved in a "reprehensible manner" with a 14-year-old girl and his conduct had inevitably caused her serious and lasting consequences.Now retired after 18 years as bishop of Bordeaux, the 78-year-old cardinal said he had asked her for forgiveness and apologised to those he had hurt.Another two former bishops were the subject of a judicial investigation while a third had been reported to prosecutors, he added.Last year, Pope Francis changed the Church's laws to make sexual abuse, grooming minors for sex, possessing child pornography and covering up abuse a criminal offence under Vatican law."
