Peace my brother
I must tell you, even though you have done excellent research, you have totally misunderstood Romans 14.
Also, I really don't know what you have against the books dictated from Paul?
Romans 14 IS NOT about eating clean and unclean foods. The chapter is a guide to Christians and Jews to stop judging one another. Mainly judging other faiths and how they worship the Lord.
This verse sums up Romans 14 in full:
Romans 14:13 (NIV) 13Therefore let us stop passing judgment on one another. Instead, make up your mind not to put any stumbling block or obstacle in your brother's way.
Paul was inspired by the Holy Spirit. The books he wrote were and still are beautiful guides as to how we should live our lives with Jesus Christ in our hearts.
Jesus is Lord
Peace and Godspeed
Pray for Israel
