The Bible is pretty clear about it - there is only one judge and that is the Almighty Himself.Psalms 9:8 And he shall judge the world in righteousness, he shall minister judgment to the people in uprightness.Matthew 7:1Judge not, that ye be not judged.These are the first words of Matthew 7. It continues on to say:Matthew 7:2And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?We cannot judge ourselves because when you get right down to it, we aren't perfect either. This theme rings throughout the Bible that there is only one true Judge.However, a lot of people take poetic license to make that whatever they want. You can and should condemn a wicked act. You can and should help a person when it reasonable to do so. You can, and should, as reference by II John, condemn a false doctrine and don't let it creep into your church, family, or life. You'll see me condemn issues of doctrine on this site but I don't name any names because I am not the judge, God is. However, when you start throwing around terms like heretic and start attacking the person, you're judging. I've seen it time and again and it's a snare that you can quickly fall into. That's what this first part of Matthew 7 is speaking about.Conversely, when the Bible comes out and says something, that's not judging. Some prime examples are homosexuality and something like violence and fornication in movies. I'm not condemning the person of my own will be doing this - it's printed in black and white in God's Book of Law that you just don't do that.It can become a fine line to walk, but you will do well if you let God's Word guide you.As for these websites, you have to be very careful with who you're dealing with. There are people out there who do exactly what Christ says in the second verse of Mat. 7 above and don't look in the mirror when they throw around accusations. Remember that Christ himself was branded as a heretic by many.
