Many have read the following verse before and so have we. We never put it together with where it came from. Peter is reflecting upon Dietary Laws from Leviticus.
1 Peter 1:15-16 but as he who called you is holy, you also be holy in all your conduct, since it is written, “You shall be holy, for I am holy.”
Did you know that Peter is quoting from the Torah (Old Testament)? Did you know that when the words “it is written” are seen that it always comes from the Torah (Old Testament)? Did you know that Peter is directly quoting from the food laws in the above mentioned verse?
Leviticus 20:25-26 You shall therefore separate the clean beast from the unclean, and the unclean bird from the clean. You shall not make yourselves detestable by beast or by bird or by anything with which the ground crawls, which I have set apart for you to hold UNCLEAN. You shall be holy to me, for I the Lord am holy and have separated you from the peoples, that you should be mine.
Dietary Law has nothing to do with health as some try to point out. It has everything to do with separating us from the rest of the nation(s). In the Bible the word GENTILE is used often. This word never existed in the original text and is a mistranslation of the word Goy(singular) and Goyim(plural) which just means other nation(s). HE wants us separated. We can easily achieve separation.
