Mario Poli takes Pope Francis' old post Argentine Mario Poli has been inaugurated as the new archbishop of Buenos Aires. ARGENTINE Mario Poli has been inaugurated as the new archbishop of Buenos Aires, taking over the post held by Jorge Bergoglio before he became Pope Francis. Poli, 66, was named to the position by Francis in late March and Vatican envoy Emil Paul Tscherrig welcomed him in the name of the pope in the ceremony at the capital's metropolitan cathedral on Saturday, saying the pontiff "accompanies us from Rome." Argentine President Cristina Fernandez, who was travelling in Peru and Venezuela, did not attend the ceremony but several of her cabinet ministers did. "The arrival of the replacement for Bergoglio generates enthusiasm, expectations and hope, and we wish him the best in his pastoral activities in Buenos Aires," said Julian Dominguez, the head of the Chamber of Deputies. Poli is a priest very much in Francis' vein, focused on pastoral work. He has been the bishop in Santa Rosa in the rural La Pampa province, and from 2002-2008 he served as one of then-Cardinal Bergoglio's auxiliary bishops in Buenos Aires, but he was not among the church officials rumoured to be top candidates for the post. He has a doctorate in theology from the Catholic University of Argentina, but before he was ordained as a priest in 1978, he earned a degree in social work from the public University of Buenos Aires, known as UBA. That apparently impressed Bergoglio, who talked about the benefits of such training in a 2012 book, On Heaven and Earth.
