due to persecution in Romania, lost all contact with the WTBTS some time in the late 50's or early 60's. They just re-studied the literature they had on hand, over and over and over again.
I remember when I was in 'experiences' of isolated groups who just studied the Bible and then later found that their beliefs totally tallied with the JWs.
Strange isn't it that this group did much the same thing and found it was the JWs who had drifted away.
