The Lady of All Nations is a Catholic Marian title sometimes associated with apparitions of the Blessed Virgin Mary to Ida Peerdeman of Amsterdam, Netherlands.
On 25 March 1945, Peerdeman reported seeing a woman surrounded in light who identified herself as "The Lady" and "Mother".
In December 1979, The Lady of All Nations Foundation purchased property in Diepenbrockstraat, Amsterdam, which became the center of the apparition cultus, and where Peerdeman came to reside.
In the succeeding messages she dictates her prayer, draws attention to her image, and speaks for the first time about the final and greatest Marian dogma: Mary Coredemptrix, Mediatrix and Advocate.
"[4] The Lady reportedly said that the definition of the Assumption had brought to a close the era of Marian dogmas having to do with Mary's earthly life, and that the "final and greatest" Marian dogma would be a definition of the heavenly role of the Lady of All Nations under the titles of Coredemptrix, Mediatrix and Advocate.
[5] Supporters of this proposal refer to it as "the fifth Marian dogma," since it would theoretically follow the four dogmatic definitions of Mary as Mother of God,[6] Perpetual Virgin,[7] Immaculately Conceived, and Assumed into Heaven.
"[11] The Lady asked a prayer be said throughout the world: Lord Jesus Christ, Son of the Father, send now Your Spirit over the earth.
[2] Despite a declaration by the Bishop of Haarlem that he "found no evidence of the supernatural nature of the apparitions", the movement continued to spread.
The reaffirmation of the Church’s position means that the devotion to “The Lady of All Nations” is not recognized as stemming from a supernatural origin.
