Theophylact of Ohrid
Catena Aurea · Lukasevangelium 1
There was in the days of Herod, the king of Judæa, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth. And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless. And they had no child, because that Elisabeth was barren, and they both were now well stricken in years. The office was that of the Priesthood, as it is said, A certain Priest of the name of Zacharias.
And that you might learn that the law of God seeketh not a bodily increase of sons but a spiritual, both were far advanced, not only in the body but in the Spirit, “making ascents in their heartb,” having their life as the day not as the night, and walking honestly as in the day. (Ps. 84:6, 1 Thess. 5:5.)
