And if John 8:7 was actually a reason to not criticize certain actions or wrongdoings, wouldn't it too apply to the "Planned Parenthood Scandal?"
Glad you asked. I've been pondering the same question.
My answer is that John 8:7 doesn't counsel us not to criticize. It counsels us not to be hypocrites. It counsels us not to presume to punish without the moral authority to do so. Talking about someone's infidelity is simple gossip. "We're better than him because..." We, as a community, need take no action in that. It's not our job to go to this guy's house and tell him he's a screwup or pretend we're perfect because we either a) didn't get caught doing our own stupid things or b) didn't happen to do the same stupid thing he did. Gossip is all about making one's self look good by pointing out someone else's wrongs.
Exposing Planned Parenthood isn't gossip, and it isn't hypocrisy to say that killing a newborn baby and harvesting his/her organs is evil. John 8:7 doesn't counsel us to stand by and hold our tongue while the innocent are murdered for profit. We as a community DO have a duty to protect the lives of other people, and spread the word when something like that is happening in order to try to win justice.
