The "Visitation of Mary" refers to the biblical event in which the Virgin Mary visits her cousin Elizabeth, who is pregnant with John the Baptist. This encounter is described in the Gospel of Luke (1:39-56) and highlights the joy and significance of both pregnancies. During this visit, Elizabeth recognizes the divine nature of Mary's child, leading to the famous "Magnificat," a song of praise by Mary. This event is celebrated in various Christian traditions, particularly in the Catholic Church, on May 31st. The Visitation emphasizes themes of faith, joy, and the connection between Mary and Elizabeth, showcasing the importance of community and support among women during pregnancy.
