That very well may be the meaning of "oklah" but oklah isn't the word used in the verse you quoted:
Rom 14:2 For one believeth that he may eat all things: another, who is weak, eateth herbs.
"Eat" is:
phagō
Thayer Definition:
1) to eat
2) to eat (consume) a thing
2a) to take food, eat a meal
2b) metaphorically to devour, consume
And "herbs" is:
lachanon; from λαχαίνω lachainō (to dig); a garden herb, a vegetable: - garden herb (1), garden plants (2), vegetables (1).
You're assertation is also lacking context. Romans 14 is conerned with eating practices, not smoking dope practices.
Also, if "herbs" is marijuana in the passage, then the statement is:
Rom 14:2 For one believeth that he may eat all things: another, who is weak, eateth only marijuana.
So one person (the strong one) eats "everything", while the weak one eats marijuana. That's complete nonsense. The proper intrepretation is that the strong one eats meats and vegetables, while the weak in faith (because they feared that the clean meats were once sacrificed to idols) eats only vegetables.
There is no 'only' in Rom 14:2
Oklah is in Gen. 1:29
If it is eaten rather than consumed by fire then you are OK with it?
The crux of Rom 14 is found in Romans 14:14
Romans 14:14
I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
As I have said all along that there is no substance to evil but that evil resides
in intention. Your intention is to deny the will of God and eradicate his gift
while persecuting those children of God which seek only peace from hostile heretics.
Romans 14: 2-3
For one believeth that he may eat all things: another, who is weak, eateth herbs. Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
The one who believes he may eat all things will soon find himself a dead fool.
Another, weak and in ill health, with knowledge will find aid in an herb
desired for its medicinal properties. You call this knowledgeable person a
witch and seek their persecution despite the word's admonition to "not judge
him that eateth." Your eyes see only sin, they are offensive and you would
be better off if you plucked them out, for you are already blind to the Holy Spirit. Go join the Taliban! They are your kind of people.
"the weak in faith (because they feared that the clean meats were once sacrificed to idols) eats only vegetables."
Think Again!
CONTEXT
'Weak' above is translated from:
Astheneo (as-then-eh'-o);
Word Origin: Greek, Verb, Strong #: 770
to be weak, feeble, to be without strength, powerless
to be weak in means, needy, poor
to be feeble, sick
KJV Word Usage and Count
be weak 12
be sick 10
sick 7
weak 3
impotent man 1
be diseased 1
be made weak 1
The passage contrasts two modes of thought; belief and knowledge.
The first is an obvious absurdity to anyone but a fool for only a fool would believe that he 'CAN' eat ALL
THINGS(Pas) and neither 'MAY' we by the law.
Pas:
Word Origin: Greek, Adjective, Strong #: 3956
individually
each, every, any, all, the whole, everyone, all things, everything
collectively
some of all types
This false belief which would bring death is contrasted
with an ill persons knowledge of herbs to restore health.
I am sure that you have never read the Essene gospel.
Basically, the rest of Romans 14 is about not seeking
conflict as regards the dietary choices of others. Why?
Because this journey is each our own, it is not for you to
whip into line any other not following what you see as the
path. Whipping will only lead you to the pit.
