J.Rutherford was like John Calvin in respect that both believed in forms of Limited Atonement, rather than Universal Salvation.
Calvin of course believed in strict Predestination of the saved and the damned.
Rutherford's Baptist upbringing may have been an influence since many Baptist groups believe in Calvin's concept.
Both guys were a couple of strange ducks.......I did spell that with a 'd' didn't I.
