Romans 14:3

3.Let not him who eats, etc. He wisely and suitably meets the faults of both parties. They who were strong had this fault, — that they despised those as superstitious who were scrupulous about insignificant things, and also derided them: these, on the other hand, were hardly able to refrain from rash judgments, so as not to condemn what they did not follow; for whatever they perceived to be contrary to their own sentiments, they thought was evil. Hence he exhorts the former to refrain from contempt, and the latter from excessive moroseness. And the reason which he adds, as it belongs to both parties, ought to be applied to the two clauses, — “When you see,” he says, “a man illuminated with the knowledge of God, you have evidence enough that he is received by the Lord; if you either despise or condemn him, you reject him whom God has embraced.” (417)
