The Messianic Jew is ignoring the new testament when some of those old testament laws were over written. We had a pastor show us a verse that in the new testament that was Jesus talking it pretty much did away with the kosher food laws. If I can remember the verse or get a hold of him I will post it.
Next time i see my brother and sister in law I am gonna ask them what they meant when they said there is a difference between a believer and a Messianic jew. By your definition and wikipedias def. a Messianic Jew is a believer with different customs pretty much.
4 Then Peter began to explain to them point by point what had happened. He said,
5 “I was in the town of Joppa praying when in a trance I saw a vision: Something like a large linen sheet descended down from heaven, lowered by its four corners, and it came right down to me.
6 When I examined it closely, I saw four-footed animals of the earth, wild animals, reptiles, and birds of the air.
7 I also heard a voice telling me, ‘Get up, Peter! Kill something and eat it.’
8 But I replied, ‘Absolutely not, Lord, for nothing common or unclean has ever entered my mouth!’
9 Then the voice from heaven answered a second time, ‘You must stop calling common what God has made clean!’
10 This happened three times. Then everything was pulled back up to heaven.
Messianic Jews are subject to different beliefs just as different denominations... if people would stop squabbling over.... rapture placement, 'to dunk or sprinkle. to use music or not, don't eat this don't eat that.....and focus on Christ, the world would be a much better place.
