St. Bernard (l. 2, de Consid.) saith to Pope Eugenius, “Who art thou? A great priest—the chief Pontiff. Thou art the prince of bishops, thou art the heir of the Apostles, thou art Abel in primacy, Noah in government, Abraham in the patriarchate; in order, thou art Melchisedeck, in dignity Aaron, in authority Moses, in judgeship Samuel, in power Peter, in unction a Christ. To thee the keys have been delivered, the sheep entrusted.” (as cited by Cornelius A Lapide, The Great Commentary)
