What is the "Magnificat"? I heard my pastor use the term "Magnificat" when preaching in the book of Luke about Mary today. What is the Magnificat?
The Magnificat (also known as the Canticle of Mary) is the section of scripture found in Luke 1:46-55, in which Mary the mother of Jesus praises the Lord. 

The term "Magnificat" comes from the Latin translation of the first line: "Magnificat anima mea Dominum" which means "my soul magnifies the Lord".
