Well...now that all foods are "clean" in this NC dispensation, it seems the only concern we have is with drinking certain beverages, since drunkenness is still a sin in this age. I don't see every choice as being moral in nature. In fact, I think that is an extreme view since I can't find any laws governing the color of clothing we should wear. And...we are warned about being morally-spiritually extreme to wit:
Eccl 7:15-18
15 In this meaningless life of mine I have seen both of these:
a righteous man perishing in his righteousness,
and a wicked man living long in his wickedness.
16 Do not be overrighteous,
neither be overwise —
why destroy yourself?
17 Do not be overwicked,
and do not be a fool —
why die before your time?
18 It is good to grasp the one
and not let go of the other.
The man who fears God will avoid all [extremes ].
NIV
Most translations render the last clause of v.18, "for the one who fears God comes forth from them all". In other words, the wise man will avoid being "overrighteous", "overwise" or "overwicked". The NIV, then, captures the sense very well in the last part of this verse which is to avoid all extremes, which is the central point to the passage.
I think a great example of this can be found in Jesus' lesson he taught in Mat 15:1-20. The Pharisees were clearly being "overwise" and "overrighteous" by adding their man-made traditions to the Law of God.
Just my 2-1/2 cents worth...
