For years the "New Testament churches" have taught that the Old Testament "laws" don't apply to them.  However, after an exhaustive study of the Greek words covering every mention of "flesh," "meat" and "food" in the New Testament (NT), we could find nothing that supported this position. Indeed, we found the exact opposite! (To view this study, please click on this link: Does the Bible Say We Can Eat Anything?)

Recently, we were told that the Old Testament doesn't uphold the dietary laws since in Genesis 9:3 Yahweh (God, also spelled as YHWH) says to Noah: 

     "Every moving thing that is alive shall be food for you; I give all to you, as I gave the green

The belief that this Scripture disputes the dietary law, giving a license to eat anything, is incorrect and the Bible proves this in several ways:

1) Noah knew the difference between clean and unclean. In obedience to YHWH's command, he took 7 of every clean animal and only 2 (1 male, 1 female) of the unclean animals (Genesis 6:19-22; Genesis 7:2-3).

2) After the flood upon departing from the ark, Noah offered sacrifice to YHWH from the clean animals, knowing that YHWH would not accept an unclean offering (Genesis 8:20) This again shows that Noah knew the difference between clean and unclean, even before the Torah ("law") was given through Moses.

3) Had Noah and/or his family eaten from the unclean animals taken on the ark, then he would have wiped out a species that YHWH had so carefully preserved! Of each unclean species, there were only two: a male and a female. So, if YHWH were saying man could eat of the unclean, He'd have just made that species extinct.

4) The position that this disputes the dietary law can only be true if Scripture can contradict Scripture, if YHWH can change His mind and thus we are saying that we believe that YHWH can contradict Himself. Since the Bible is inerrant (Psalm 19:7-11) and God doesn't change (Malachi 3:6; Hebrews 13:8), then this belief is a mistaken one.
