I recently learned a new way of understanding what "turning the other cheek" is. Rather than a passive acceptance of abuse, it's like putting a mirror on the abuser and making them look like the villains (which they actually are). The post is very much alike.
The Cheek Slap in Jesus’ Day
In Jesus’ day, hitting a person on the cheek was a forceful insult, but it was not considered a violent assault. Here, Jesus is specifying a strike on the right cheek, which implies a back-handed slap. Striking someone with the back of the hand (3) could demand a doubled fine because it was “the severest public affront to a person’s dignity.” (4)
But Jesus is not suggesting that his followers should stand around and take abuse. First, turning the left cheek was a bold rejection of the insult itself. Second, it challenged the aggressor to repeat the offense, while requiring that they now strike with the palm of their hand, something done not to a lesser but to an equal. In other words, turning the other cheek strongly declares that the opposer holds no power for condescending shame because the victim’s honor is not dependent on human approval—it comes from somewhere else. (5) This kind of action reshapes the relationship, pushing the adversary to either back down or to treat them as an equal.
