So the Pope, the apparent representative of God and Christ here on earth, couldn’t proclaim the Gospel or stand true publically for God and Christ, because he was trying to protect certain innocent lives?
Sounds like a stand up sort of guy, that Pope. Yeah, I want him representing Christ.
He did proclaim the Gospel and stand true for "God and Christ" (are you a Mormon?).
Various Jewish groups explicitly asked him to lay low and not make a public production out of chastising the Germans. All it did was lead to more reprisals.
Yes, Pope Pius XII was more concerned with saving Jewish lives than with justifying himself to history.
