Turning the other cheek is for each of us, individually.
I have often pointed out that it is a blessing that except for the woman taken in adultery, we have no example from Our Lord of how to respond to violence toward another. Plainly Christians must imitate His example: diplomacy first.
But, if one can't talk down those intent on violence, how does the Christian respond?
Sometimes it is better to be a pacifist and permit evil, while not doing evil. Sometimes it is better to fight, yes, even to kill, though that is evil, to resist a greater evil.
This tension is plain in Orthodox tradition, which has never forbidden military service by the laity (once being in the legion didn't require pagan practices), but requires clergy in major orders to be pacifists; has services for blessing the arms of Orthodox laymen going to war and special versions of the trisagion prayers of mercy for Orthodox warriors, but prescribes penance for those who kill, even in a war sanctioned by duely constituted authorities, even by an Orthodox emperor.
Brother, you err. To stand by and allow an evil to continue is to be complicit in its work. Christians are to RESIST evil, and in some cases that means by force. Nowhere in scripture (not even from the mouth of Jesus) does it say we are to submit to evil and allow ourselves to be murdered. Please, take time on your knees and consider what you would do if face with a murdering hoard of Muslims trying to attack your basilica and to burn down your home with your family inside. Stop, be quiet before God, and ask Him for wisdom.
Might I suggest that when you are done with that, you take the next plane to Nigeria and offer assistance?
