In Matthew Jesus tells us to "Judge not, that ye be not judged" (to use the familiar King James version). The word here translated "judge" is krino (Gk), a very broad term which can embrace several concepts, including to have an opinion or preference (beige carpet is nicer than pink) and to esteem one thing over another (say, feeding the hungry over killing them). Obviously, there are things that we are going to have an opinion about and things we should esteem over others, so it falls upon the context of the verse to let us know what is being discussed. Looking at that, it would seem that Jesus is discussing our relationships with other people. One of the possible meanings of the Greek word is to make a decree, or to put it in modern terms, to "label" someone, to write him off as a hothead or selfish or petty,etc, thereby coloring other people's opinions of him, not to mention his opinion of the one who has labeled him. If I do this to people, they in turn will label me as judgmental.
In Timothy, Paul instructs his mentee to "rebuke" when the occasion calls for it. The Greek word here is epitimeo. Interesting word -- has to do with value and can actually mean to honor as well as to chide. Another possible translation of this word would be to evaluate, or better yet, to charge. The prefix "epi" indicates that this is an act of volition, whereas a judgment (krino) is something we can do without even realizing it.
We can make judgments in our hearts against people, judgments that really mostly hurt ourselves. It seems to me that to rebuke someone is an act of commision, and to do so and be in the right you must speak from some position of authority over the one(s) being rebuked. As a teacher I can do little of the students' opinions (judgments) of me, but if one of them rebukes me, he will be punished.
So the short answer is yes.... *grin*
