Catholic bishops are meeting to discuss the Roman Catholic church's response to the sexual abuse of children by members of the clergy for the first time. The Vatican says it wants four days of reflection and discussion with survivors and it is likely to be a defining moment for Pope Francis. Before the conference, Archbishop Eamon Martin offered a message to survivors and victims of abuse in Ireland asking for forgiveness and ensuring that church activities are as safe as possible for children and vulnerable people. Meanwhile women in the Contemplative Sisters of St John who were sexually abused by priests when younger, then silenced, are now speaking out. CNN has spoken to several women who say they are victims of the devastating sexual, psychological and spiritual abuse they suffered within the community. See
