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.

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.
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.
Here their whole character is comprehended in their justice, but it is well said before God, for a man by affecting a popular good-will might seem just to me, but not be just before God, if that justice instead of springing from simpleness of heart, was a mere presence carried on by flattery. Perfect then is the praise, “that a man is just before God;” for he only is perfect who isapproved by Him who cannot be deceived. St. Luke comprehends the action in the commandment, the doing justice in the justification. Hence it follows, walking in all the commandments and justifications of the Lord. For when we obey the command of heaven we walk in the commandments of the Lord, when we observe justice we seem to possess the justification of the Lord. But to be “blameless” we must “provide things honest”, not only before God, but also before men; there is no blame when both motive and action are alike good, but a too austere righteousness often provokes censure. A righteous act may also be done unrighteously, as when a man out of ostentation gives largely to the poor, which is not without just cause of blame. It follows, And they had no son, because Elizabeth was barren.
