Catena Aurea · Lukasevangelium 1
And Mary arose in those days, and went into the hill country with haste, into a city of Juda; And entered into the house of Zacharias, and saluted Elisabeth. And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost: And she spake out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb. And whence is this to me, that the mother of my Lord should come to me? For, lo, as soon as the voice of thy salutation sounded in my ears, the babe leaped in my womb for joy. And blessed is she that believed: for there shall be a performance of those things which were told her from the Lord.
But soon the blessed fruits of Mary’s coming and our Lord’s presence are made evident. For it follows, And it came to pass, that when Elisabeth heard the salutation of Mary, the babe leaped in her womb. Mark the distinction and propriety of each word. Elisabeth first heard the word, but John first experienced the grace. She heard by the order of nature, he leaped by reason of the mystery. She perceived the coming of Mary, he the coming of the Lord.
