Be courteous - This word also φιλόφρων (philophrōn) occurs nowhere else in the New Testament. It means “friendly-minded, kind, courteous.” Later editions of the New Testament, instead of this, read (ταπεινόφρονες tapeinophrones) of a lowly or humble mind. See Hahn. The sense is not materially varied. In the one word, the idea of “friendliness” is the one that prevails; in the other, that of “humility.” Christianity requires both of these virtues, and either word enforces an important injunction. The authority is in favor of the latter reading; and though Christianity requires that we should be courteous and gentlemanly in our treatment of others, this text can hardly be relied on as a prooftext of that point.
