I'm not ignoring this passage because Christ is not saying here it is OK to eat pork or"unclean foods". It would contradict what is written. There are several scriptures the unlearned use to justify eating "unclean" foods and this also is one of them. But we must remember to read them in the proper context. Sometimes it helps to read the whole chapter first to get an understanding of what is going on. Man is so concerned with the traditions they have created and make no matter of what God's tradition or standard is. What law are you breaking for not washing your hands...none. What Christ was telling them here in this passage is that not to concern ourselves with the washing of our hands but the standard that God has put forth and that is having a pure heart.
I can see why people use this and other scriptures to justify eating pork but what needs to be understood first is that Christ/Paul/Peter wasnt always talking about foods. God uses earthy symbols so that the "earthy man" will understand Him better. Just like in Acts 10 this is also a scripture the unlearned use, Peter wasnt even talking about foods but the Gentiles. You know Christ spoke in alot of parables which cause people to make interpatations but if you let the Book speak for its self you dont have to worry about interpatation. If Christ told us he came to do the will of the Father...who sent him....why would he change what God commanded in the Dietary Law? question like this made me go back and search because I believe God's word to be truth and not tainted. Line upon line precept upon precept.
I hope you gained an understanding if not I would be more then happy to discuss it further.
p.s. I not offend nor does it bother me when yourself/others question my faith. It provides the opportunity to testify and sometimes gives me a chance to learn something new,that I can take back to the crew and we can reason about it. Those that know Christ will understand what Im saying and those that dont wont get me at all. "the harvest is great but the labourers are few".
