Recently, I attended a Sunday School lesson in my church regarding the above mentioned verse. To summarize, the text is the famous one where Jesus teaches believers to "turn the other cheek." As the Sunday School class was discussing these things, a great number of elder Christians in the group began to state that the interpretation of the verse is that Believers are to be Pacifists. This, however, seemed to contradict John 2:15 where Jesus drives out the money changers at the temple in rage with a whip of chords. Further, a number of other members in the class are both strong Christians AND Veterans of the US Military (men which I respect greatly for their strong faith, by the way). They oddly enough either stayed silent at the idea of a pacifist Christianity, and some even agreed with it, but I'm not entirely sure that the pacifist interpretation is absolutely correct.
Now before anyone says I'm trying to promote violent Christians on here, let me clarify. I believe every word which Jesus says about peace. I know it's 100% true and that Christians are called to peace. Don't doubt that one bit. I myself am a lover not a fighter by nature, but I still believe in fighting for what I love. All I'm asking is for an interpretation of the verse which explains why, on one end, Jesus talked of turning the other cheek and on the other He made a whip of chords and beat a bunch of sinners out of a temple in a rampage. Are there places where Christians can fight (or even use deadly force, as with veterans), or not? If so, where do we draw the line, since either yes or not could be risky answers here? What does "turn the other cheek" actually mean, and to what degree are we to tolerate abuse before we are permitted to make a whip of chords ourselves?
