It is important to know the source of quotes in Scripture. The reader is expected to know the meaning behind a quote from the old testament.
1 Peter 1:16 “Because it is written, Be ye holy; for I am holy.”
The quote is from Leviticus 11:44, God’s health laws, the food laws. The implication is that being holy is effected by what we eat. Therefore the question, can one be holy before God as commanded in 1 Peter 1:16 and still eat pork?
