The best records we have of Jesus’ teachings are the gospel books that are typically referenced. And there are enough references to Jesus of Nazareth in other texts to suggest this is what he was like and taught.

Jesus’ teachings on government and social structures are nuanced and difficult to apply to our human structures, because he proposed a government ruled by a perfectly good, benevolent monarch (which, in theory, is a great system if you can guarantee the monarch is really perfectly good). He preached a lot about “the kingdom of God” and contrasted it to how we do things on earth. So the point was never to provide a blueprint of how we should do government, but that there was something above all earthly governments that superceded it all.

Unfortunately, people have used those teachings in very bad ways (the same reasoning that the religious leaders used to kill Jesus). All of that to say–there are a lot of congregations that have more in common with the Pharisees than the early church.
