ERNOLFO di ROCHESTER. – Benedictine bishop and writer, b. at Beauvais ca. 1040, d. at Rochester on 15 March 1124. A disciple of Lanfranco (v.), he followed him to England, where he became prior of the monastery of Canterbury, abbot of Peterburg (1107), and bishop of Rochester (1114).
He wrote: De rebus ecclesiae Roffentis (PL 163, 1443–56), important for the history of that diocese; Tomellus de incertis coniugis (PL 163, 1458–74); Responsiones ad quinque quuestiones de sacramento Eucharistiae (in L. D’Achery, Spicilogium, 2nd ed., Paris 1723, pp. 470–74). The Eucharistic questionnaire submitted to him by his confrere Lamberto gave him the opportunity to expound, with singular precision, the doctrine of the real presence under the individual species.
