The Nazis did more than that. They took over the Protestant churches (except for a persecuted remnant that did not bow to the anti-Christ). The Nazis tried to make the churches become little more than outlets for Nazi propaganda. A lot of real Christians who resisted this were sent to prison or concentration camps. For decades the authority of the Bible had been downgraded, so a lot of church leaders were well-prepared to let the Nazi pagans destroy what was left of Christianity.
Your last line bothers me, because Christianity is of course not something that can be destroyed. It can be abandoned, but it will still always be there.
It is impossible to generalize the effect that Nazism had on German Protestants. Differnet denominations fared differently. The Catholic had historically been so much more unified that they had their own effective political party until 1933. When the Nazis suggested that the protestants elect their own "national biship" to represent them, they were enthusiastic. Many of them had already participated in a movement called the German Christians before Hitler became chancellor. The German Christains became increasingly sympathetic to the Reich as time when on. This being Germany, most were Lutherans. Througout the course of the war, the Nazi Party had ever growing influence on the Lutheran Church. The much smaller Methodist and Episcopalian Churches were completely subverted by Hitler. Of course, many good Christians resisted, actively or quietly. Not telling you anything I think you don't already know, just adding to it. Ever HS history book you pick up today will discuss the Catholic Church under Nazi rule. People forget that Germany was a Protestant country, and most Nazis were Protestant.
I’m sorry, I didn’t mean to imply that they were not fascist b@stards to the church. My point was that they discounted all of the books of the Epistles by referring to their author as “the Jew”. It’s nonsensical since they were all Jews, but being schtoopid doesn’t seem to have kept them from being very, very mean, a lesson that should not be lost on us as “that man” continues to have his way with us.
