The Case for Conversion: Welcoming Non-Jews into Messianic Jewish Space
I see very serious issues with this article.
Conversion does not solve the problem, but actually is unbiblical, to the point of destroying the prophesy concerning the purpose of Gentiles and the fact that God had always planned on calling Gentiles as Gentiles.
If there was ever a place for Jews and Gentiles to be One in Messiah, it is in Messianic Judaism, but one in Messiah means one Spirit and vision, and not all made to be 'Jews'.
In the body of Yeshua, the assembly, we are all different parts, different people, different cultures, from different languages and different nations. I have had an opportunity to worship in a place where there were people from countries around the world. From the America's, from the Far East (China, Japan, Korea), from Europe, From Africa, from the middle east including Israel and Egypt. I wish I could draw a picture in everyones mind. We all sang the same song, but each in their own language, praising the Lord, together in unity. A person who spoke French prayed for me. I didn't understand what they were saying, but I didn't need to.
There is a commonality in that we are all members of the Kingdom of Heaven. Our identity is in being New Creations, something entirely new, and the Old Man is dead. Knowing who we are goes beyond any nationality or ethnicity. It is something which can not be shaken, and that is the identity which matters. In Messianic Judaism, the worship is culturally Jewish, but that doesn't mean that those who are not Jewish lose their heavenly bought identity of being Saints, sons of God by adoption.
Rather then conversion, which not only further muddies the waters, but in the end will make our witness as Messianic Jewish people and will end up hurting those who 'converted' as they will never be accepted as Jewish. What is needed is a fuller understanding of scripture, and identity.
