Established Before Sinai. Still Required at the End.
"Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female." Genesis 7:2
Noah knew clean from unclean BEFORE the flood, BEFORE Sinai, BEFORE the law was given at the mountain. This is not a "Jewish custom." It is not a "Mosaic ordinance." It predates Israel as a nation. Yahuah built the distinction between clean and unclean into creation itself.
"They that sanctify themselves, and purify themselves in the gardens behind one tree in the midst, eating swine's flesh, and the abomination, and the mouse, shall be consumed together, saith Yahuah." Isaiah 66:17
This is END-TIMES language. Those eating unclean things are consumed at judgment. If dietary laws were abolished at the cross, why is Yahuah judging people for eating swine at the end?
Acts 10 was about PEOPLE, not food.
"Elohim hath shewed me that I should not call any MAN common or unclean." Acts 10:28
Peter himself interpreted the vision. It was about Gentiles being welcomed into fellowship. Not about eating pork. Peter never ate unclean animals. He said so himself: "I have never eaten any thing that is common or unclean" (Acts 10:14).
Read the full context. The Pharisees challenged Yahusha about eating with unwashed hands (Mark 7:5). Yahusha rebuked their TRADITIONS (handwashing rituals), not Torah's food laws.
The parenthetical "thus he declared all foods clean" in some translations (Mark 7:19) is a translator addition. The Greek says "purging all foods" referring to the digestive process, not a declaration abolishing dietary law.
"Come out from among them, and be ye separate, saith Yahuah, and touch not the unclean thing; and I will receive you." 2 Corinthians 6:17
By this logic, if you ARE touching unclean things, He will not receive you. Once you start keeping your temple clean, you receive His Spirit and start being convicted to follow His other commands.
"That ye abstain from meats offered to idols, and from blood, and from things strangled." Acts 15:20
"For Moses of old time hath in every city them that preach him, being read in the synagogues every sabbath day." Acts 15:21
The apostles gave four starting requirements for new believers. Then verse 21 explains why only four: "Moses is read in the synagogues every Sabbath." They expected new believers to learn the REST of Torah gradually through weekly Sabbath teaching. This was a LEARNING PROGRESSION, not the full list of requirements.
