Are Messianics ''Noahides? if not, why?
Some believe in what Paul/Shaul taught about becoming believers in the Messiah Yeshua...>
Eph 2:11 Therefore remember that once you, the Gentiles in the flesh....
Eph 2:12 that you were at that time separate from Messiah,
alienated from the commonwealth of Israel, and strangers from the covenants of the promise, having no hope and without God in the world.
Eph 2:13 But now in Messiah Yeshua you who once were far off are made near in the blood of Messiah.
Eph 2:19 So then
you are no longer strangers and foreigners, but you are fellow citizens with the holy ones, and of the household of God....
So, no need to "convert" to anything.
