Thomas Boston, Works, 2:50-51:
Beware of rash judging those that have any lineaments of Christ’s image upon them. Ye may judge and condemn the evil actions of the best of men, if ye be sure from the word that they are evil. But, O my soul! enter not into the secret of those who presumptuously take upon them to judge men’s state, hearts, and consciences, upon slips of human infirmity and weakness.
