LOL...right killing it by NOT suffocating it and making sure all the blood is drained makes pig, dog, snake meat clean...There are some common sense dietary guidelines, guidelines to make sure the Gentiles do not do with food that pagan's do with their food.
you are ADDING to what and how Peter interpreted the vision again...is something NOT even Paul did or he would have simply said.so...he didnt and what he did say you twist and mix into your own blood sausage...Peter said unstable minds would do so...God said what He has made clean don't call unclean. That goes for food and people.
Your unclean heart craves unclean...think what you will eat in heaven and in the new earth...think what they ate before sin entered...eat that get used to it...practice here to be prepared
Or eat as He did...because you do wish to be more like Him...
