Which Cheek was it?
Matthew 5:39 But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.
Note the right cheek, also notice that most people are right handed thus a full blown attack/punch would occur on the left cheek. This verse was in reference to a slap, not a full attack. IMHO...if someone attacks your pride or something small, turn the other cheek, if they come with force, well I think you said it right.....
