Biblically validated, from the words of Peter in holy scripture:
Act 10:28 And he said to them, "You yourselves know how unlawful it is for a man who is a Jew to associate with a foreigner or to visit him; and yet God has shown me that I should not call any man unholy or unclean.
This is how Peter interpreted the vision that God showed him. This is the interpretation that is present in scripture. There is no other interpretation of this event in scripture. This is the authoritative source and the bottom line.
