There was in the days of Herod, the king of Judea, a certain priest named Zachariah, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elizabeth.

Holy Scripture tells us that not only the character of those who are praiseworthy but also their parents must be praised, so that the transmitted inheritance of immaculate purity, as it were, in those whom we wish to praise, may be exalted. What other intention is there in this passage of the holy Evangelist, except that St. John the Baptist be renowned for his parents, his wonders, his duty and his passion? Thus Hannah, the mother of St. Samuel, is praised. Thus Isaac received from his parents nobility of piety, which he handed down to his descendants. Therefore the priest Zechariah is not only a priest but also of the course of Abijah, that is, a noble among his wife’s ancestors. “And his wife,” it says, “was of the daughters of Aaron.” So St. John’s nobility was handed down not only from his parents but also from his ancestors—not exalted through worldly power but venerable through the religious succession. For the forerunner of Christ ought to have such ancestors, that he be seen to preach a faith in his Lord’s advent that is not suddenly conceived but received from his ancestors and imparted by the very law of nature. –.
