Judge not according to the appearance, but judge righteous judgment.
Let us not therefore judge one another any more: but judge this rather, that no man put a stumbling block or an occasion to fall in his brother's way.
1 Cor. 4:3-5
But with me it is a very small thing that I should be judged of you, or of man's judgment: yea, I judge not mine own self.  For I know nothing by myself; yet am I not hereby justified: but he that judgeth me is the Lord.  Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.
1 Cor. 5:11-12
But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.  For what have I to do to judge them also that are without? do not ye judge them that are within?
For he shall have judgment without mercy, that hath showed no mercy;
and mercy rejoiceth against judgment.
Be kindly affectionate one to another with brotherly love; in honor preferring one another;
1 Cor. 10:12
Wherefore let him that thinketh he standeth take heed lest he fall.
And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things.
