How to put this without sounding as though I am condescending to an idiot:-

I imagine Sydney Carter was pretty well versed in The Sermon on the Mount, but really he wasn't the sort of person that would spend his time examining the books of the OT looking for salvation.

And he certainly wasn't the man who would look through those pages seeking for ways to denounce and insult a tranche of his fellow man.

His brand of Christianity was people based. And very gentle and decent.
