Stalin famously asked, "How many divisions has the Pope?" The tyrants successors of the Evil Empire found out when the Pole Karol Wojtyla became Pope.
Steve Hayward considers (from segments of his work-in-progress, The Age of Reagan: Lion at the Gate, 1980-1989) what Karol Wojtyla meant when he proclaimed "Be not afraid!" when he was selected Pope. The Polish Pope brought a transformation of consciousness among Poles that had massive consequences for the whole world. Poland was the first country he visited after becoming Pope, and Hayward recounts how that went, what the Soviets thought, how they were out-thought and out-gunned by the Pope. He broke the sorcerer’s spell. The rest you know.
Curiously, most of those who quote Stalin omit Piuss rejoinder:
"Tell my son Joseph that he will meet my divisions in heaven."
