The Nazi movement was an intellectually weak political force that used propaganda effectively. It made appeals on the lines of Socialism, religion, patriotism etc as the need arose. Individual Nazis could be atheist, Catholic, Lutheran etc as their personal beliefs allowed. The only religion that was given consistent treatment was Judaism which was attacked insanely as part of a wider attack on Semites who were also bizarrely identified with Bolshevism.
In many ways Nazism was an "anti-movement" in that it defined itself as for a mythic Germany, but more so against Jews and Communism.
As such Hitler and his movement were complex and often self contradictory, and religious groups treated him in various ways. Individual religious leaders and communities opposed the violence and evil of the Nazis, and were often suppressed. Pope Pius XI opposed Nazism and excommunicated the Nazi party. Pius XII was more concerned with Communism and sought to use Nazism as a tool to destroy the definitely atheist Communist Soviet Union. Many religious leaders adopted this uneasy alliance as the best policy in bad times and some even lived to regret it.
The intellectual weakness of Nazism (it became a party based increasingly around one personality) meant that during its growth phase it was harder to define and oppose. It could appeal to workers against bosses, it could appeal to anti-Semites or anti-communists at the same time. It could move from a street fighting terror organisation with armed thug battalions into a sober looking conservative ally of the army and present itself as the saviour of the state.
Some Nazis wanted a return to an imagined ancient pagan purity, with idols in churches. others looked to bizarre theosophical type occultism. Others were boring "Church on Sunday, death camp on Monday" type functionaries who observed religion as a duty rather than love of God.
I don't think there's a consistent Nazi religious position., Hitler seems to have treated religion as an institution to be manipulated, but it does not seem to have been treated as important or given an organised approach.
