They think, “Jesus was cool. I like him, and I’m gonna try to be like him.” Kind of like their guiding light is what would Jesus do? But there isn’t a focus on identification, recruiting others, judging others based on their religion, fear of God, fear of punishment for sinning, respect for clergy as an authority, rituals, worship, etc. Basically, just the example of Jesus’ life.
inb4: Christian lol!! got em!
People who model their lives after the teachings of Jesus are pretty rare. I think it is more psychologically valuable because Christians are able to psychologically transfer the moral qualities of Jesus to themselves. Jesus is “good” in ways that most Christians today don’t even give a shit about, but it gives him moral character, and so it allows Christians to feel like they have moral character as well.
In fact, I was going to link to the article about “moral licensing” as though I actually knew what I was talking about (I don’t) and I see there is a section about exactly this idea, where people see themselves as having the moral qualities of others in their in-group:

So in a way, the stories about Jesus allow Christianity to fill an important spiritual role in people’s lives: assuring them that they are good people. But it’s tricking them, and Jesus has to be a model of good morality for this trick to work.
