Thematic Bible: Judging uncharitably

Speak not against one another, my brethren; he that speaketh against his brother, and judgeth his brother, speaketh against the law, and judgeth the law; but if thou judge the law, thou art not a doer of the law, but a judge. Now there is but one lawgiver, who is able to save and to destroy: who art thou then that judgest another?
