A special service was held in the city on Sunday afternoon.Among those who attended the service at St Eugene's Cathedral was the All Ireland Primate Cardinal Seán Brady and the former Bishop of Derry Séamus Hegarty.During Sunday's service, Bishop McKeown told the congregation: "Our society knows many places where people feel discarded or beyond hope. Many people feel prisoners of their past while others seem to glide on, presumed masters of their future."That can happen because of neglect and abuse in its multiple forms; it can come from ill health or lack of satisfying chances to contribute to society; it can be reinforced by being labelled in education or social status; it can be born from the mistakes that they or others have made."He went on to say during his homily that Pope Francis is quite explicit in stating that many people "feel crushed by the economy of exclusion, scorned by the new idolatry of money, victims of a financial system which rules rather than serves and prisoners of the inequality which spawns violence.""In saying this he is not being modern or new. He is simply reflecting the Jesus of the Gospel. And he is not just speaking about some foreign lands, his words can find echoes in our own country as well."Pope Francis appointed the Co Antrim native as the new Bishop of Derry in February.He takes over a post which has been vacant since 2011, when Bishop Hegarty retired due to ill-health.Bishop McKeown was born in Randalstown in 1950 and was ordained at the age of 27 as a priest for the Diocese of Down and Connor.Prior to his ordination, he studied at the Pontifical Gregorian University in Rome and worked as a presenter for Vatican Radio.In 2001, he was appointed auxiliary bishop of Down and Connor a post which he held for over a decade.
