It is part of the rich tradition of our Catholic faith to petition the popes regarding the proclamation of Marian dogmas.

 

For example, millions of petitions by the Christian faithful led to the dogmas of the Immaculate Conception (1854) and the Assumption (1950). With every Marian dogma, extraordinary graces are poured upon the world through Our Lady’s most powerful intercession.

 

In 1915, Cardinal Mercier of Belgium began an international petition movement for the papal definition of the Blessed Virgin Mary as the world’s “Spiritual Mother.” Now, one hundred years later, well over 8 million priests, religious and lay faithful and over 800 Cardinals and Bishops from more than 180 countries have sent petitions to recent popes in favor of the solemn definition: the Mother of Jesus is Spiritual Mother of all humanity in her three maternal roles as Co-redemptrix, Mediatrix of all graces and Advocate.

 

In one line (or more) please tell the Holy Father that you "support the dogmatic proclamation of Mary as the “Spiritual Mother of all Peoples."
