Consecration of Portugal (1931-05-13)
In November of 1928, for the feast of Christ the King, the Portuguese bishops already solemnly consecrated Portugal to the Sacred Heart of Jesus. As the continuation and natural completion of this first act the consecration of Portugal to the Immaculate Heart of Mary hhas been done on May 13, 1931.
Act of consecration of Portugal to the Immaculate Heart of Mary
The proof that [God] gives us [of the authenticity of His requests] is the special protection of the Immaculate Heart of Mary over Portugal due to its consecration to Her. Those people whom you write to me about have a good reason to be scared. All this would have happened to us, had our bishops not paid attention to the requests of Our Good Lord, and prayed with all their heart for His mercy and the protection of the Immaculate Heart of Mary, our Blessed Heavenly Mother.
On October 24, 1940, Sister Lucia writes to Pope Piux XII:
Our Lord promises a special protection to our little nation due to the consecration made by the Portuguese Prelates to the Immaculate Heart of Mary, as proof of the graces that would have been granted to other nations, had they also consecrated themselves to Her.
