Culture is the greatest determining factor with what is normal for dress and grooming.  What is modest and what isn’t.  The presence or lack of facial hair can falsely imply goodness depending on what culture you’re in.  For example, some men prize their beards and consider it sinful to shave.  Some men who are in religious leadership positions must be clean shaven.

“The worst sinners, according to Jesus, are not the harlots and publicans, but the religious leaders with their insistence on proper dress and grooming, their careful observance of all the rules, their precious concern for status symbols, their strict legality, their pious patriotism… the haircut becomes the test of virtue in a world where Satan deceives and rules by appearances.” Hugh Nibley
