I won't get into them on the board. I don't want to stir up controvery on the board.. They are not well thought of by the jewish community... To be clear I am not speaking of all messianic Jewish groups,but Jews for Jesus specifically...If you want details I can PM you.
My last encounter with them was nearly 20 years ago. So I can't speak to what's happened since then. They were always off beat but didn't seem particularly dangerous.
A lot can happen in 20 years.
Would you care for a non-smoking seat in Limbo?
