There probably were members of the Church hierarchy that deliberately kept silent. That's lamentable, but what does that prove? Catholics don't claim impeccability for any clergy person, even the pope. Certainly non-Catholic Christians are also sinful. Just as many or more Protestant clergy capitulated in the face of Nazi persecution. That's no reason to condemn the teachings of Protestantism per se. Finally, as the NY Times and Albert Einstein attest, the pope was the lone voice speaking out against the Nazis during the early years of the war.
I doubt that any significant number of clergy thought that Hitler was doing something noble. That's a bit of stretch, to say the least. You should have some evidence of that before you slander people, and then extrapolate from that to smear the entire clergy. Slander is a sin.
From the newspaper article that I posted, which you seem to have NOT read!!
On the other hand, some churchmen, including Cardinal Alfred Baudrillart, the rector of the Catholic Institute in Paris, were outspoken supporters of the Vichy government and the Nazis. Baudrillart called Hitler's mission a noble and inspiring one.
