In what may be the most removed from context and the most maligned verse in the Bible, Matthew 7:1 . . .

"Judge not, that ye be not judged."

. . . much other Scripture is ignored in order that man might be made to feel justified in anything he does, for if a person cannot be judged, then there is no wrong that can be confronted. Christ goes on to say in giving the reasoning for Matt 7:1, in the immediately following passage -

"For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.

And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?

Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye?

Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye." vs 2-5

Verse 1 is a warning against unjust judgment, not at all a forbidding of judgment for which we are commanded to make.

Furthermore, beginning in vs 6 onward Scripture itself requires that we make several judgments -

For example, “Give not that which is holy unto the dogs, neither cast ye your pearls before swine . . . ", who are the dogs and who are the swine?

Or "Beware false prophets"; who are they?

We are to judge matters between ourselves that pertain to this life, a commandment unto us . .

"Dare any of you, having a matter against another, go to law before the unjust, and not before the saints? Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters? Know ye not that we shall judge angels? how much more things that pertain to this life? If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church. I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren? But brother goeth to law with brother, and that before the unbelievers." 1 Corinthians 6:1-6

The Word of God has far far and far again more to say about us judging, commanding us to do so, than it ever does about not judging. Scripture only warns us of judging in unrighteousness and hypocrisy.

As men, we do not like to be judged, that is why even those who are His tend to cling to an out of context verse like a drowning man, forcing Matthew 7:1 to take on a blasphemous meaning to not judge when it is simply a warning against unjust and hypocritical judgment.
