And the role of Tito and his spreading communism in Yugoslavia played what role in the Church's support?
Josip Broz Tito was a Croat, Roman Catholic and Communist dictator. Some say that he was excommunicated from The RC Church in 1945 after putting Stepinac on trial. Maybe he was excommun icated even earlier. However, Tito was received in private audience with Pope Paul VI. Only God knows what they spoke about.
Usually, the extraordinary privilege of private audience is not granted to people who are not suporting RC church. Especially not to two bit Communist dictators.
Hopefully, one day, the Vatican archive will be opened and we will learn more.
