Although I don't know where you get the odd idea that it's wrong to kneel before a superior. That's an egalitarian Enlightenment idea, not a biblical one.
Yes, it is a Biblical one. The apostles never allowed people to kneel before them. And, who ordains someone to be superior over another? In Christ we are all equal, and each has his/her own calling. I don’t blindly follow someone just because they claim to be superior over me. The name Adolph Hitler comes to mind.
