The hypocrite (Greek- hupokrites) was originally an actor. Theatrical make-up in those days took the form of a mask which the actor wore. On it would be painted the character and the mood which the actor portrayed. It might be a smiling face which hid the sad heart of the actor behind it. It might be a face of virtue which hid behind it a life of vice. In acting there can be a great discrepancy between the part which is played and the reality of the life which lies behind it… The same can be true of faith. We can profess much and possess little. Indeed there is always the temptation in Christian fellowships to pretend to be something other than what we are.
