Okay, before we go any further, sounds like I need to be clear about my opinion. I rather admire them. All the ones I've ever met know the Bible better than most Christians I've ever met.
That said, the reason I ask is two-fold. As of late, I see many on this site -- some who aren't into arguing even -- saying two things that surprised me.
1. Most Messianic Jews were never Jewish to start. (I don't know. Never asked. Didn't care, but that site seems to confirm that.)
2. They're legalists.
Now "legalists" has become code on here for "not saved," so I'm really checking if that is a common perception on this site.
So far? It doesn't seem to be, which is a good thing in my opinion.
