Yes mam.Well you can take the OT version but I will take the NT way as in Peters dream/vision.
Jesus confronted by the religious said this,
Matthew 15:
17 Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught?
18 But those things which proceed out of the mouth come forth from the heart; and THEY DEFILE A MAN.
19 For 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 unwashen hands defileth not a man.
Romans 14
14 I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
15 But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died.
However in esteeming our brethren better than ourselves so as not to be a stumbling block we must NOT eat what they consider unclean in front of them......... These will answer for their own lack of knowledge, understanding and wisdom before God in accepting what man or woman tells them as opposed to what God says !
