The Golden Rule (Matthew 7:12)

“The Golden Rule is a ‘call to creativity.’ Far from being a wooden rule to look back and ‘do to others what others have done to you,’ which would be counsel to reciprocate proportionally, it is counsel to look forward and to anticipate what others would like done and so be initiatory. And Jesus’ command to act in this creative way applies not only to disciples’ relations with other disciples, but with all human beings, as the use of the word ‘people’ rather than ‘brothers’ or even ‘neighbors’ indicates.”

— Bruner, Matthew, A Commentary

Jesus Fulfills the Law (Matthew 5:21-26)

Q. 135. What are the duties required in the sixth commandment?

A. The duties required in the sixth commandment are, all careful studies, and lawful endeavours, to preserve the life of ourselves and others by resisting all thoughts and purposes, subduing all passions, and avoiding all occasions, temptations, and practices, which tend to the unjust taking away the life of any; by just defence thereof against violence, patient bearing of the hand of God, quietness of mind, cheerfulness of spirit; a sober use of meat, drink, physic, sleep, labor, and recreation; by charitable thoughts, love, compassion, meekness, gentleness, kindness; peaceable, mild, and courteous speeches and behavior: forbearance, readiness to be reconciled, patient bearing and forgiving of injuries, and requiting good for evil; comforting and succoring the distressed, and protecting and defending the innocent.

The Role of the Law (Matthew 5:17-20)

“[Jesus] is saying that our attitude to the law of God is an index of our attitude to God himself. If we treat the law lightly and encourage others to do so, we show that we are strangers to the promise of the new covenant in Christ. But if we love and keep even the least of the Lord’s commandments, and we encourage others to do so as well, that is a sure mark that we love Christ and belong to his kingdom.”
