That came after the Nazis stabbed the Catholics in the back. When they wanted support from the Catholic Church, they sang a different tune and seduced the Catholics. Betrayal followed after the Nazis felt they didn't need them anymore.
I was referring to how the Vatican and the Nazi regime reached an agreement, and part of that agreement was that every bishop had to take an oath of loyalty to the Reich.
Reichskonkordat - Wikipedia
Article 16 Before taking possession of their diocese, the bishops shall take an oath of loyalty either between the hands of the Reichsstatthalter in the state (Land) in question or between those of the president of the Reich, the formula of which shall be the following: "Before God and on the Holy Gospel I swear and promise, as becomes a bishop, loyalty to the German Reich and to the Land of (name of Land). I swear and promise to respect the government established according to the constitution and to cause the clergy of my diocese to respect it. In due solicitude for the welfare and the interests of the German Reich, I will endeavor, while performing the spiritual office bestowed upon me, to prevent anything which might threaten to be detrimental to it."
A big motive for the Catholics is that they wanted money from the government for their schools. It sounds like today when religious schools go begging to the government for money. It looks like socialism to me when the government is paying for religion. I think it's dangerous; and I think I see both parties in the US trying to buy religious leaders. Both parties had Catholics speaking at their conventions. Trump got a bishop, but Biden had to make do with only a priest.
I believe that within every organisation there are good and the bad, the RC has it's bad mob always struggling to take control within history proves. it's the same with anything, it's like a cancer, everyone has it only a healthy body keeps such at bay.
When a totally new type of Government comes in, it's only natural that their be agreements as such, concordance. one would be stupid not to. I do not remember how it goes with Communism, mainly it's that they totally reject any regard to Christians. some type of formality would be reached I am sure in regards to some things as well. it's all got to do with legality. only the uneducated in ignorance would claim that the RCC was doing wrong in trying to service their faithful in Germany, if they did not do as such they would be guilty of abandoning the faithful in fact.
What are you saying that the Christian schools should have no funding at all ?
As for the RC schools in Australia or any religious schools the people have every right that government gives money as it does to any school for the children, the religious schools parents only top what's given themselves, I think it works out saving the tax payer in some regards over all. but some schools do look to be shady as to funding getting way more than they should, with deals, especially with Islamic schools or Jewish as it's taboo to mention anything in their regards. but they can come up with BS after BS with Christian schools all they like, but most of it is just uneducated dribble from the Socialist claiming half baked lies to try to bastardise anything that is not State school, why do they do such well the State schools peddle Socialism and if you have a Christian school they may not be on the same page with that program. but from what I seen with my youngest the RC school was given up to Socialism in the last 2 years, even the principle was a atheist and the Priest was a atheist moron as well, you may as well just of had a socialist convention their. straight out blasphemy straight up from the Priest is what I heard (you are all awesome ! turn to one beside you and tell them they are awesome ) you have to be kidding me ! did Jesus say that we are all awesome

. the bastard was a snake.
Many a Jew is working within the RCC and they have bastardised the Church, creating Vatican 2. they created WW2 as well they offered up the 6 million Jews to their god as well, that's why they call such a holocaust ( a burnt offering ) they are claiming god did such in fact, no it was the works of man in fact.
Socialism will always work to undermine a Church, because such is a mans works and as such it rejects God is above all. god is equal to man, because that's the mantra that all are equal.
