Luke 1:5

Divine Scripture teaches us with respect to those whom we commemorate, that not only the characters of the men themselves, but of their parents also, ought to be praised, that they might be distinguished by an inheritance, as it were, handed down to them of unspotted purity. Now not only from his parents, but also from his ancestors, St. John derives his illustrious descent, a descent not exalted by secular power, but venerable from its sanctity. Complete then is that praise which comprehends birth, character, office, actions, and judgments. The office was that of the Priesthood, as it is said, A certain Priest of the name of Zacharias. His birth is implied in the mention made of his ancestors. Of the course of Abia, i. e. of high rank among the noblest families.

(noc occ.) St. Luke commences the history of his Gospel with Zacharias and the birth of John; relating one marvellous event before another, the less before the greater. For since a virgin was about to become a mother, it had been fore-ordained by grace that the old should previously conceive. He fixes the time, when he says, In the days of Herod, and in the following words adds his rank, king of Judæa. (in Matt. cap. 2.). There was another Herod, who killed John; he was tetrarch, whereas this one was king.

(in Luc. Evang.) Now the time of Herod, i. e. of a foreign king, bears witness to our Lord's coming, for it had been foretold, The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come. (Gen. 49:12.) For from the time that our fathers came out of Egypt, they were governed by judges of their own nation, until the Prophet Samuel; and then by kings, until the carrying away to Babylon. But after the return from Babylon, the chief power was in the hands of priests, until the time of Hyrcanus, who was both king and high priest. He was slain by Herod, after which the government of the kingdom was delivered over by the command of Augustus Cæsar to this same Herod, a foreigner, in whose thirty-first year, according to the prophecy we have mentioned, Shiloh came. (in Homil. in vigil. S. Joh. Bap.) For John was allotted a Priestly tribe, that he might with the more authority herald forth a change of priesthood. There were Princes of the Sanctuary or High Priests, both of the sons of Eleazar and the sons of Thamar, whose courses according to their respective services when they entered into the House of God David divided into twenty-four lots, of which the family of Abia (from which Zacharias was descended) obtained the eighth lot. (1 Chron. 24.) But it was not without meaning that the first preacher of the new covenant was born with the rights of the eighth lot; because as the old Covenant is often expressed by the seventh number on account of the Sabbath, so frequently is the new Covenant by the eighth, because of the sacrament of our Lord's or our resurrection.

Wishing to show also that John was legally of Priestly descent, Luke adds, And his wife was of the daughters of Aaron, and her name was Elisabeth, for it was not permitted to the Jews to take a wife from any other tribe but their own. Elisabeth by interpretation signifies "rest," Zacharias "the remembrance of the land."
