A certain man had two sons. By the elder son is commonly expounded the Jewish people, who for a long time had been chosen to serve God; and by the younger son, the Gentiles, who for so many ages had run blindly on in their idolatry and vices. (Witham) — Some understand this of the Jews and Gentiles, others of the just and sinners. The former opinion seems preferable. The elder son, brought up in his father’s house, &c. represents the Jews; the younger prodigal is a figure of the Gentiles. (Calmet)
