Romans 14:4

“Who art thou that judgest another man's servant, etc..] This is another reason, dissuading from censoriousness and rash judgment, taken from civil things; one man has nothing to do with another man's servant; he has no power over him, nor any right to call him to an account for his actions; nor has he any business to censure or condemn him for them, or concern himself about them: so the believer supposed to be judged, does not belong to him that takes upon him to judge and condemn him; he is another's servant, he is the servant of God: he is chosen by God the Father for his service, as well as unto salvation; he is bought with the price of Christ's blood, and therefore not his own, nor…”

This is a principle of common sense and common propriety. It is not ours to sit in judgment on the servant of another man. He has the control over him; and if “he”…”
