Recently Moishe Rosen stated on a public forum the following:
"Jews for Jesus has opposition who are unprincipled and are willing to adopt guises so that they appear to be other than what they are."
I'm not sure what Rev. Rosen is talking about, but it's interesting that JFJ would complain about dishonest tactics given the history of Jews for Jesus. JFJ is proud that they always are (supposedly) upfront and honest about who they are, but JFJ used to commonly practice something that proves this is not the case (I'm not sure if they still practice it). When JFJ musicians or street theatre groups would perform in public, they would commonly use "ringers" to attract attention from passers-by and thus generate a crowd of onlookers. This was especially prevalent during New York City summer "campaigns." These ringers would pretend to be regular spectators but in reality they were usually JFJ volunteers who were asked or told to watch the proceedings in a neutral role, without any identifying clothing such as a Jews for Jesus shirt or jacket.
I'm sure there are other more glaring examples of JFJ's dishonesty, but I never got close enough to the inner circle to discover these.
