"We raised our eyes to Our Lady, who said to us with kindness and sadness: – You have seen hell, where the souls of poor sinners go. To save them, God wishes to establish in the world devotion to My Immaculate Heart. If what I say to you is done, many souls will be saved and there will be peace. The war is about to end, but if they do not cease offending God, another worse war will begin during the pontificate of Pius XI. [...] To prevent this, I will come to ask for the consecration of Russia to my Immaculate Heart and the Communion of Reparation on the First Saturdays. If they accept My requests, Russia will convert and they will have peace; if not, it will spread its errors throughout the world, promoting wars and persecutions of the Church. The good will be martyred, the Holy Father will have much to suffer, various nations will be destroyed. In the end, My Immaculate Heart will triumph."
