What a lot of these people are is idolators.
Not in terms of the realness or unrealness of who they worship, but in terms of how they’ve warped their focus away from the reality and turned it towards a fantasy of their own construction.
By definition, an idol is an image with no god behind it.
What they have done is taken the idea of Jesus and created a false image of him, nothing like the reality, to carry around in their back pocket, or to wave around on signs, and pull out and shove in people’s faces to justify all manner of unChristlike behavior.
It is a “worship” that is fundamentally self-centered rather than deity-centered, wherein the deity in question is more of a pocketbook get-out-of-jail-free card than directive to live by, and more of a status symbol than a guiding light.
That people will, without a shred of self-awareness, rest themselves assured that Jesus would want them to tip their waitress with a Jesus pamphlet made to look like folded-up money (to take only one example out of many) is the ultimate dismissal of everything the original stood for.
There is a line in the Bible about Jesus meeting his false worshipers and saying “I do not know you.” It seems like plenty of so-called Christians have beaten him to the punch with how quick they are to say they don’t know him.
