History hasn't looked kindly on the Catholic Church during WW II.
The conventional narrative is not the whole story. At six in the morning on Sunday, 12 March, a procession snaked toward
the bronze doors of St. Peter’s. Swiss Guards led the line, followed by
barefoot friars with belts of rope. Pius took his place at the end,
borne on a portable throne. Ostrich plumes stirred silently to either
side, like quotation marks.
Pius entered the basilica to a blare of silver trumpets and a burst of applause. Through pillars of incense he blessed the faces. At the High Altar, attendants placed on his shoulders a wool strip interwoven with black crosses.
