What's the root definition of the word "judge" in Matthew 7:1?
Judge not, that ye be not judged. (Matthew 7:1 KJV)
According to Kittel’s TDNT the basic sense in Greek literature is ‘to part,’ ‘to sift,’ which leads to the sense ‘to divide out’, ‘to select’, ‘to value’, with the most common meaning is ‘to decide’. From this root is also means ‘to judge’, ‘to assess’, ‘to go to law, to dispute with’. Also ‘to seek justice,’ or ‘to be accused’.
Christians were never commanded to "Not Judge". Christ said that the criteria you use to judge another is the same one that will be used on you. To point out Hypocrisy. He never said "Not to Judge".
