MAZZELLA, CAMILLO. - Jesuit, theologian, and cardinal, born at Vitulano (Benevento) on 10 February 1833, died in Rome on 26 May 1900. He studied at the Seminary of Benevento directed by the Jesuits and, after being ordained priest in 1855, entered the Society of Jesus in 1857. He taught dogmatic and moral theology at Lyon (1860-67); then he moved to the same teaching position in the United States (Georgetown and Woodstock), from where in 1887 he was called by Leo XIII to the chair of theology at the Gregorian University to contribute to the revival of scholasticism. He was created cardinal in 1886 and in 1897 was consecrated Bishop of Palestrina; he worked tirelessly in the Roman Congregations, especially those of Studies and of Rites, of which he was prefect. He was a clear and prolific theologian, a good exponent of the Neothomist movement.
Among his publications are to be noted: *De Deo creante* (Rome 1880); *De Religione et Ecclesia* (ibid. 1892); *De Gratia Christi* (ibid. 1892); *De virtutibus infusis* (ibid. 1894). Also to be recalled are: *Risposta ad alcune questioni sopra il ritorno dei Greci scismatici alla Chiesa cattolica* (ibid. 1887) and the anonymous work: *Rosminianarum propositionum... tri-tina theologica* (ibid. 1887).
