It refers to Jesus Christ, symbolizing His role as a sacrificial lamb who takes away the sins of the world. This concept is rooted in the Bible, particularly in the Gospel of John, where John the Baptist identifies Jesus with this title. In worship, "Agnus Dei" is often included in the Mass and other religious services. It is also a popular subject in art and music, inspiring various compositions, including works by composers like Bach and Palestrina. The imagery of the lamb is commonly depicted in Christian iconography, representing purity and sacrifice.
