R. Erlanger is also known as the author of the very-popular (among chasidim, teen-aged ones in particular), anonymously-published booklets named "חסידות". As such, he can be considered as an unofficial representative of mainstream Chassidic thought (l'afikai Chabad-style Chassidus).
I found a written copy of a speech he gave about Emunah. I picked it up and I was surprised by the content. I mean, I always knew that some people have these kind of worldview, but I never thought that such a famous Mashpia as R. Erlanger, disseminates such views. There actually is some truth to what he says, but the way he says it . . . Well, see for yourself. Here's one page, I highlighted the sentences I found bothersome.
