If all this was true, then why did Hitler need the Enabling Act to be passed? and why did he need the votes of the Catholic Center Party for it to pass?
Without the votes of the Center Party, the Enabling Act would not have passed. It was not a done deal until the deal was done.
The only way to protect the right of Catholics to worship in Germany was to negotiate, which is exactly what the Protestant majority had already done.
What about the right of people to just live lawfully, to speak out when necessary, to write articles, to operate businesses, to organize opposition, to help their fellow man, to save those being led away to slaughter, to follow the dictates of their consciences, and all those other God-given rights. Were those rights protected too?
Or were all of those rights traded in for that sacred right to go to church, to fill a pew, to light a candle, and close your eyes and ears while all else was coming apart in your community and country around you?
The Enabling Act giving Hitler power was in place before the concordat. We can both speculate why Hitler wanted the concordat, but that would just be speculation. However, we can draw conclusions based on the facts:
2. During the negotiations preceding the concordat, Hitler arrested 92 priests.
3. During the negotiations preceding the concordat, Hitler closed down nine Catholic publications.
4. The Four-Power Pact between the Nazis, Britain, France, and Italy was in place.
5. Protestants made their own agreements with Hitler before the Catholic concordat.
6. In Pacelli's own words, the purpose of the Reichskonkordat was: "not only the official recognition (by the Reich) of the legislation of the Church (its Code of Canon Law), but the adoption of many provisions of this legislation and the protection of all Church legislation."
You conclusion: The concordat brought Hitler to power.
You conclusion is fantasy.
