Yes indeed, "Christians" have historically twisted and turned what Jesus says to suit their theology into a labyrinth of contradictions, virtually ignoring what is actually commanded to placate their desire for a feel-good theology. And then they use cherry picked passages of Paul and Acts to justify their beliefs (many of them most likely interpolated by anti-judaizers years afterward). The scripture most assuredly says that they will burn. I'd love to help them, but they often are doggedly determined to head for the fire as if what Jesus says doesn't actually matter. How "Christians" are able to deal with the cognitive dissonance of virtually ignoring everything Jesus says about how your behavior and adherence to the commandments determines your fate is beyond me.
What "Real Christianity" looks like is close to Messianic Judaism. Anything else is one of the heresies spoken of in the scripture. Heck, even Paul would ferociously disagree with how the mainstream churches treat his epistles and their doctrines. They have all kinds of ways of twisting what it directly, plainly says, to suit their one-size-fits-all dogmas of not having to actually do anything that might be inconvenient. For all their emphasis on Acts 15 (Which was most likely interpolated by anti-Judaizers), they often have no problem eating bloody steaks. It's as if they don't want ANY burdens or restrictions that might possibly make a single inconvenience.
They think they are allowed to fornicate, but Paul says Fornicators don't make it to the kingdom: "Well shut up Paul, the doctrine of grace beats your own words, right?" It's as if they don't even want to listen to what Paul himself says, while relying on Paul's epistles (albeit very cherry picked), the way they justify their lifestyle in the face of what even Paul says against it is hilarious. They think they go to heaven just for believing, not only did Jesus condemn such a view (Matthew 7:22-23), but even PAUL condemned this view. The understanding of Paul to begin with is so radically skewed it's amazing, maybe I should be sticking up for him, because the same "Christians" who use him to contradict what Jesus teaches, don't even abide by what he says. Whether it's ignorance, apathy, or rebelliousness, I can't decide.
