After Mary learned that she would be the mother of Jesus, she visited her cousin Elizabeth, who was pregnant with John the Baptist. When Elizabeth heard the voice of “the mother of my Lord,” her baby leaped in her womb for joy. Mary then praised God with what became one of the earliest Christian hymns, called the Magnificat. It is a poetic outpouring of praise, joy, and trust in God. It has been set to music by Claudio Monteverdi, Johann Sebastian Bach, and, more recently, by John Rutter.
