Joe - There are lots of logical conclusions about the connection between the Catholic Church and the Nazi doctrine.

"In the performance of my spiritual office and in my solicitude for the welfare and the interests of the German Reich, I will endeavor to avoid all detrimental acts which might endanger it."
--Mandatory pledge for newly appointed Catholic Bishops, as stated in the Reichskonkordat, or Concordat Between the Holy See and the German [Nazi] Reich, Article 16

Joseph Ratzinger, now Pope Benedict XVI, wrote:

"...it cannot be denied that a certain insufficient resistance to this atrocity [the Holocaust] on the part of Christians can be explained by an inherited anti-Judaism present in the hearts of not a few Christians."

That is not to say that all Catholics are Nazis or that all Nazis were Catholics. Ratzinger says it very nicely when he calls it insufficient resistance. In fact, there were only a small minority of Catholic priests who resisted at all. Most priests performed according to the welfare and interests of the German Reich.
