Lifted from Wikipedia:
"[H]is mother had given the church about 100 million yen (US$720,000), a parcel of land she had inherited from her father, and the house where she lived with her three children; she subsequently declared bankruptcy in 2002. She had continued donating to the church following the bankruptcy. A male relative later recalled being contacted by Yamagami and his siblings to complain that they had no food at home, prompting the relative to deliver meals and money for living expenses. [..] Yamagami's older brother, who had a longtime struggle with cancer, was not able to afford medical treatment; he died by suicide in 2015."
To me, that sounds quite a bit worse than your average Christian church.
There are certainly some predatory Christian hucksters out there; people
like Kenneth "I need my private jet to spread the gospel" Copeland spring to mind, but there are many more (as well as many more abusive ones). Religion is often a comparatively "easy" target for abuse.
However, the religion of Christianity as a whole isn't centred around the concept of "send me your money". I think that's the main difference: is the religion as a whole primarily centred around abuse, or is it just various groups within the religion that operate like that?
There are plenty of cults within Christianity, but Christianity as a whole?
I'm sure there are more formal and academic descriptions, and things can become a bit tricky around the edges for sure, but I find "is it primarily centred around abuse of its members?" to be a reasonably workable every-day distinction.
