I think its important not to cut off the context. I am not going to discuss Col 2:16 because you refuse to bring in the context and we can make the bible say anything we want by not allowing it to interpret Itself. We can close our ears to it, but it doesn't take away God's Truth.
Was Jesus talking about food when He said "it’s not what goes into the body that defiles a person but what comes out that defiles him" or was He using it as an illustration and said plainly what He was referring to which was never about food. The premise was not washing your hands before eating and used food as a parable, that wasn't even about food as Jesus clearly states.
Mat 15:1 Then the scribes and Pharisees who were from Jerusalem came to Jesus, saying, 2 “
Why do Your disciples transgress the tradition of the elders? For they do not wash their hands when they eat bread.”
3 He answered and said to them, “Why do you also transgress the commandment of God because of your tradition? 4 For God commanded, saying, ‘Honor your father and your mother’; and, ‘He who curses father or mother, let him be put to death.’ 5 But you say, ‘Whoever says to his father or mother, “Whatever profit you might have received from me
is a gift
to God”— 6 then he need not honor his father [
a]or mother.’ Thus you have made the [
b]commandment of God of no effect by your tradition. 7 Hypocrites! Well did Isaiah prophesy about you, saying:
8 ‘These people [
c]draw near to Me with their mouth,
And honor Me with
their lips,
But their heart is far from Me.
9 And in vain they worship Me,
Teaching
as doctrines the commandments of men.’ ”
10 When He had called the multitude to
Himself, He said to them, “Hear and understand: 11 Not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man.”
12 Then His disciples came and said to Him, “Do You know that the Pharisees were offended when they heard this saying?”
13 But He answered and said, “Every plant which My heavenly Father has not planted will be uprooted. 14 Let them alone. They are blind leaders of the blind. And if the blind leads the blind, both will fall into a ditch.”
15 Then Peter answered and said to Him, “Explain this parable to us.”
16
So Jesus said, “Are you also still without understanding? 17 Do you not yet understand that whatever enters the mouth goes into the stomach and is eliminated? 18
But those things which proceed out of the mouth come from the heart, and they defile a man. 19 F
or out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies. 20 These are the things which defile a man, but to eat with unwashed hands does not defile a man.”
If you're comfortable eating something God deemed an abomination until His Second Coming Isa 66:17, that's a decision once can make, its all about decisions.
