I said Marxism is a Godless Religion. The Nazi sub-sect added antisemitism to the basic Socialist ideology, and may have claimed they were on God’s side, but no-one would say they were Christian. Many Catholic priests were sent to the death camps for speaking out against Hitler, so I question your statement on Church Support; read this for a less biassed view.
