None can match the power and eloquence of Rav Shimshon Rafoel Hirsch:
There can be true peace among men only if they are all at peace with G-d. One who dares to struggle against the enemies of what is good and true in the eyes of G-d is – by this very struggle – one of the fighters for the “covenant of peace” on earth.
Conversely, one who, for the sake of what he imagines to be peace with his fellow men, cedes the field without protest and allows them to stir up strife with G-d makes common cause – by his very love of peace – with the enemies of the “covenant of peace” on earth.
