Eugenio Pacelli says his first Easter Pontifical Mass as Pope Pius XII. He speaks generally about peace, but says nothing about Italy's bombing of Tirana and occupation of Albania which occurred just two days earlier, nor does he say anything about Germany's invasion of Czechoslovakia from one month ago.
All Pius XII has to offer is abstractions:
"Is it not the case that when violent weapons replace the scepter of justice, the shining prospect of peace gives way to the horrid and cruel fires of war."
It's certainly not an expression of support for how the fascist governments are engaged in wars of aggression, but it's also not a clear and specific criticism.
