In 2009 Father Raniero Cantalamessa, preacher to the Pontifical Household, gave a lecture to Pope Benedict XVI and the papal household, restating the Roman Catholic Church's view that Gioacchino da Fiore was a heretic.
He formerly served as a professor of ancient Christian history and the director of the Department of Religious Sciences at the Università Cattolica del Sacro Cuore in Milan, resigning in 1979.
The current Apostolic Preacher, Capuchin Friar Father Raniero Cantalamessa often presides over the homilies in the chapel and is occasionally used by Pope Benedict XVI.
