Why is "uniformity" of Christian worship a problem?
Well, let's see now. If your whole religion is based on "This Was the Son of God, and you should listen to what he says", then you would expect there to be some uniformity and agreement on what he actually said and what he stood for.
2000 years of schism, reformations, counter-reformations, burning heretics, inquisitions, would indicate- um, no, Jesus didn't make himself very clear.
