We need to be honest when we get into the Jesus echelon of things, lest we misrepresent the Lord. While none of His believers are going to be perfect on earth, they will still more or less echo His nature, which is that of great sacrifice for the sake of what is truly good — things like mercy, grace, love, and humility, things against which there is no law.
This is the problem with cowboy-olatry: it is about an image, an idol. Even Wayne’s script writers spoke more, as Wayne simply obeyed the script.
Now if within this framework, Wayne illustrated a Jesus grade of goodness, it is by all means worthy of pointing out. But the appearance should follow the real thing. The cart should not be before the horse.
I quite agree with you, Idol worship is a vanity whether the icon is graven or celluloid.
