OK, let me now go to the person most Christians turn to last, Jesus. I'll save Paul for last because he is more complicated, as Peter tells us 2 Peter 3:15 And think of the long-suffering of our Lord as salvation (as our beloved brother Paul also has written to you according to the wisdom given to him
2 Peter 3:16 as also in all his letters, speaking in them of these things; in which are some things hard to be understood, which the unlearned and unstable pervert, as also they do the rest of the Scriptures, to their own destruction).
Before I post this, let me point out an irony to everyone. It was this very topic that changed my view on food and the Law as a whole. I was trying to prove we, as Christians, could eat pork and were no longer under the dietary code that convinced me from scripture we were wrong.
Anyway, the most important commandment according to Jesus is You shall love the Lord your God with all....(you know the rest). If we love our Father, why do we try so hard to not do what He asks. If for no other reason then respect, let alone the price He paid for us?
The most common verses used, to say we can eat what ever we want, by Jesus are Matthew 15:20, Mark 7:2, 5
Here is Matthew in context...
Matthew 15:1 Then the scribes and Pharisees who were from Jerusalem came to Jesus, saying,
Matthew 15:2 Why do your disciples transgress the tradition of the elders? For they do not wash their hands when they eat bread.
Matthew 15:3 But He answered and said to them, Why do you also transgress the commandment of God by your tradition?
Matthew 15:4 For God commanded, saying, "Honor your father and mother"; and, "He who speaks evil of father or mother, let him die by death."
Matthew 15:5 But you say, Whoever says to his father or mother, Whatever you would gain from me, It is a gift to God;
Matthew 15:6 and in no way he honors his father or his mother. And you voided the commandment of God by your tradition.
Matthew 15:7 Hypocrites! Well did Isaiah prophesy of you, saying,
Matthew 15:8 "This people draws near to Me with their mouth, and honors Me with their lips, but their heart is far from Me.
Matthew 15:9 But in vain they worship Me, teaching for doctrines the commandments of men."
Matthew 15:10 And He called the crowd and said to them, Hear and understand.
Matthew 15:11 Not that which goes into the mouth defiles a man; but that which comes out of the mouth, this defiles a man.
Matthew 15:12 Then His disciples came and said to Him, Do You know that the Pharisees were offended when they heard this saying?
Matthew 15:13 But He answered and said, Every plant which My heavenly Father has not planted shall be rooted up.
Matthew 15:14 Let them alone. They are blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.
Matthew 15:15 Then Peter answered and said to Him, Explain this parable to us.
Matthew 15:16 And Jesus said, Are you also still without understanding?
Matthew 15:17 Do you not yet understand that whatever enters in at the mouth goes into the belly, and is cast out into the waste-bowl?
Matthew 15:18 But the things which come out of the mouth come from the heart, and they defile the man.
Matthew 15:19 For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies;
Matthew 15:20 these are the things which defile a man, but to eat with unwashed hands does not defile a man.
Keeping this all in context, it was about eating with unwashed hands. It wasn't about WHAT they were eating but HOW they were eating. Jesus went on to condemn them for placing their teachings and traditions above the commandments. Jesus being a Torah observant Jew would only consider those foods God said were OK to eat as food, and would never have eaten anything else.
I'd like to leave you with one last thing from Jesus.
Matthew 5:17 Do not think that I have come to destroy the Law or the Prophets. I have not come to destroy but to fulfill.
Matthew 5:18 For truly I say to you, Till the heaven and the earth pass away, not one jot or one tittle shall in any way pass from the law until all is fulfilled.
Matthew 5:19 Therefore whoever shall break one of these commandments, the least, and shall teach men so, he shall be called the least in the kingdom of Heaven. But whoever shall do and teach them, the same shall be called great in the kingdom of Heaven.
Heaven and earth are still around, and there are still are things that haven't happened yet, so the whole law is still in tact.
Also notice that this isn't a salvation issue, it is an obedience issue. Those who teach that even the smallest part of the law has been done away with appear to be in heaven. They are just called the least. Why aim so low?
