Here is the deal, the truth. Websites and blogs, authored by "Christians", that attack other believers and churches is essentially the body of Christ turning on itself, the church attacking the church. When the body attacks itself it is essentially a form of spiritual cancer. This is why I call it Cyber Gossip. Gossip, whether true or false or disguised as a prayer request, is talking or writing or blogging about someone else without them present. Gossip is a sin. I learned a song when I was a kid in Sunday School, "Oh be careful little eyes what you see..."
Come to me to talk about someone behind his or her back, especially in a negative, critical spirit and I would tell you to your face, "Don't gossip. Go talk to this person face to face". These critics today would write negatively about Peter and John without ever speaking to them in person. Their response would probably be, "I can't get a meeting with Peter and John." Exactly the point!
Your job, my job, as believers is not to run around playing the role of deputy Holy Spirit. I'm not the one who will judge. God is the almighty God and the church, the Body of Christ, belongs to him so let Him do the judging. Let God fix the "problem". There are churches in our community that I disagree with in some areas and would even think they are wrong doctrinally but it's not my place to post a blog or web site devoted to tearing their church down. Peter and John were appointed by God to be apostles and if someone has been put in a place of leadership in the church I better not be attacking them. (2 Kings2:23-25)
