Recently added (Oct. 31, 2019) by Pope Francis to the Roman Calendar, the Memorial of Our Lady of Loreto recalls the mystery of the Incarnation.
Since the Middle Ages, veneration for the Holy House of Loreto has powerfully illustrated the evangelical virtues of the Holy Family. A Marian Litany, also known as the Litany of Loreto, has its first-known origins at the Shrine of Our lady of Loreto (Italy), where its usage was recorded as early as 1558.
