On February 16, 2008, Cardinal Carlo Caffara gave an interview with Tele Radio Padre Pio. He was asked about the prophecy of Sister Lucia dos Santos that speaks about “the final battle between the Lord and the kingdom of Satan.”
Cardinal Caffarra explained that Saint John Paul II had commissioned him to plan and establish the Pontifical Institute for Studies on Marriage and Family. At the beginning of this work, the cardinal wrote a letter to Sister Lucia of Fatima through her bishop, since he could not do it directly.
“Inexplicably, since I did not expect a reply, seeing as I had only asked for her prayers, I received a long letter with her signature, which is now in the archives of the Institute,” the Italian cardinal said.
“In that letter we find written: ‘The final battle between the Lord and the kingdom of Satan will be about Marriage and the Family.’ ‘Don't be afraid, she added, because whoever works for the sanctity of Marriage and the Family will always be fought against and opposed in every way, because this is the decisive issue.’ Then she concluded: ‘nevertheless, Our Lady has already crushed his head’.”
… If the foundational pillar is damaged, the entire building collapses and we're seeing this now, because we are right at this point and we know it.
