I've been reading the trial transcript and I found this little nugget (page 1028). This comes while the prosecution is questioning Rutherford:
Q. That being your view of it - that a man who was consecrated must not engage in war, then, that is your idea, that you are opposed to all war?
A. If you ask me individually, I say my individual inclination is to go into war, because that has been my ambition from youth to lead an army.
