"SDA are about the closest to being Jewish without being Jewish."
But the SDA don't keep Passover and the other Jewish festivals plus they are Trinitarian.
I think the closest would be the Church of God, the Armstrong groups.
So I guess that would make them 'about' the closest but not the closest, right?
But now we've gotten into vain babblings that edify no one, haven't we?
The SDA only keeps the Sabbath and the dietary laws. They still have crosses, false Christ's hanging on the walls, keep Easter and Christmas, and don't keep the Levitical Holy Days.
The spin-offs from WCG are closer, and some of us tend to think of ourselves as being adopted into the house of Abraham, and thus "Jews" by the modern meaning of the word.
The closest Christian congregation to being Hebrew would the the Messianic Congregations, IMO
