I have a quote from a statement from Pope Francis in the thread.
St. Pope JPII alluded to it as well. He makes a point in Rosarium Virginis Mariae that “worthy of special note” is Pope Leo XIII calling the rosary an “effective spiritual weapon”.
And here’s Pope Benedict quoting Pope JPII on the same point:
When we see, in the famous painting of Our Lady of Pompeii, the Virgin Mother and the Child Jesus giving the Rosary beads to St Catherine of Siena and St Dominic respectively, we immediately understand that this prayer leads us through Mary to Jesus, as Pope John Paul II taught us in his Letter Rosarium virginis Mariae, in which he explicitly mentions Bl. Bartolo Longo and the charism of Pompeii. The Rosary is a spiritual “weapon” in the battle against evil, against all violence, for peace in hearts, in families, in society and in the world.
Also, I don’t know what you mean by “post-Vatican II saint” but Padre Pio was only canonized in 2002, and he’s the first picture posted in this thread.
St. Josemaria Escriva, the second picture in this thread, died in 1975, post-Vatican II, and was also canonized in 2002.
Fr. Calloway’s book “Champions of the Rosary” contains a story about Mother Teresa (died 1997, canonized 2016, both dates long after Vatican II) going through an airport security checkpoint:
As Mother Teresa passed through the airport security checkpoint, she had to endure that embarrassing procedure that is part and parcel of our troubled times: “Any weapons on your person?” Unexpectedly, the childlike yet remarkably bold sari-clad woman replied in the affirmative! She did have a weapon. She then indicated the Rosary beads dangling from her hand.
