If we apply to the above
verse Jesus’ own criterion (“every good tree bears good fruit, but a bad tree
bears bad fruit”—Mathew 7:17) we will know that it is unlikely that Jesus did say
it.
When I practiced it, I
found that I was encouraging others to slap (whether in its literal or
figurative sense) me more and more. The same is happening in large scale when
countries practice tolerance. We know many countries who “turn the other cheek”
when attacked, and it only invites more trouble (which means Jesus’ advice is
counterproductive).
But see what happens if
you return more than what you receive in view of the principle God Himself
follows. (Exodus 20:5, 6) You probably succeed in correcting the other person.
We have modern example in this regard. Japan attacked Pearl Harbor as part of
their aggressive/imperialistic policy. And US made them reap the consequences
[it was like jaws for tooth, not just tooth for tooth—bombing of Nagasaki and
Hiroshima], and Japan learned the lesson: Japan stopped attacking other nations
altogether.
Interestingly, even
Jesus himself did not practice “show the other cheek” advice (which is of
course attributed to Jesus). When slapped, Jesus made a manly response saying: “But if I'm speaking the truth, why are you beating me?” (John 18:23) Because he was yet to make
his final statement on this: “Behold, I am coming soon, bringing my recompense
with me, to repay each one for what he has done” (Revelation 22:12)
which means he has never told us to ‘turn other cheek also when slapped on the
left.’
