The Catechism in Questions & Answers

288. Did Jesus say anything else about the commandment to love one’s neighbour?

In addition to the parable of the Good Samaritan, Jesus summarised the following principles on neighbourly love in the socalled “golden rule”.

The term “golden rule” was coined in Europe in the seventeenth century in reference to the statement contained in Matthew 7: 12. Today the “golden rule” is a widely held principle in interpersonal relationships even outside of Christianity.
