In addition to self defense being a fundemental value in Judeo-Christian faith, the following are a collection of quotes from other religious and civic leaders on the use of arms:
Dalai Lama XIII:“If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun.” (Seattle Times, May 15, 2001)
Mahatma Ghandi: “And why do I regard the British rule as a curse?…It has reduced us politically to serfdom. It has sapped the foundations of our culture, and, by the policy of disarmament, it has degraded us spiritually. Lacking inward strength, we have been reduced by universal disarmament to a state bordering on cowardly helplessness.”
The word Kirpan has two roots – the first root is: Kirpa, which means "Mercy, grace, compassion, kindness" and the second root is Aan, which in turn means "Honor, grace, dignity".
Sikhs embody the qualities of a "Sant-Sipahie"—a saint-soldier. One must have control over one's internal vices and be able to be constantly immersed in virtues clarified in the Guru Granth Sahib. A Sikh must also have the courage to defend the rights of all who are wrongfully oppressed or persecuted irrespective of their colour, caste or creed.
These are just a few examples, but in general, faith does not demand that we allow ourselves to be victimized. Herbert Weschler's famous quote:
"the privilege of killing in self-defense derives from 'the universal judgment that there is no social interest in preserving the lives of aggressors at the cost of those of their victims"
I hope this provides some diversity to the faith argument in support for arms as both a reasonable and rational tool for people of a great many faiths.
