Again, the main difference between Catholicism and Christianity is that Catholicism revolves around a Church that operates no differently than a secular government. Church and state are merged in Catholicism. Christianity, according to the Bible, is incredibly submissive and is inherently passive. Given the contradictions between Hitler’s own speech, it’d be unwise to call him a “Christian”, in fact, he’s often inaccurately referred to as an atheist.
I find it interesting that you declare the Catholic Church to be not Christian based on the New Testament, which was, as it happens, assembled and defined by synods and councils of the Church:
https://en.wikipedia.org/wiki/Synod_of_Hippo
https://en.wikipedia.org/wiki/Councils_of_Carthage#Synod_of_397
Note how the Council of Carthage, in addition to listing the agreed-upon books of the Bible, recommends that the martyrs be honoured on their feast days, and clearly mentions priests. In other words, when the New Testament was assembled, certain Catholic teachings were the norm throughout the majority of Christendom.
Granted, Protestants reject the Deuterocanon because the Jews didn’t include it (well, not all Jews, anyway), despite retaining all the New Testament books, neither adding nor removing any.
To reject the Church as having strayed from the truth is one thing, but to say that it is not Christain because its base structure is misaligned with the Bible doesn’t seem to be a very tenable position, considering that the New Testament canon was defined within that structure (the canon was assembled by a council of bishops, and had to be ratified by Rome, etc.).
