ANSWER: Sixth, that we do not hurt, or hate, or be hostile to our neighbor, but be patient and peaceful, pursing even our enemies with love. Seventh, that we abstain from sexual immorality and live purely and faithfully, whether in marriage or single life, avoiding all impure actions, looks, words, thoughts, or desires, and whatever might lead to them. Eighth, that we do not take without permission that which belongs to someone else, nor withhold any good from someone we might benefit.
In Matthew 5:21-26, Jesus explains the full meaning of four familiar words: You shall not murder. What does he say? What does he want us to do instead of hosting hurt, hate, and hostility in our hearts? See also Matthew 5:43-48. Some thoughts to ponder:
What's the alternative? Jesus offers two remarkably specific and practical commands. Be reconciled; make friends. How simple that is--and yet how hugely difficult and costly! It will almost certainly involve climbing down from the high pedestal on which you have placed yourself...But genuine humans don't live on pedestals; they have their feet on the ground, on a level with everybody else.--N. T. Wright, Matthew for Everyone: Part 1 (WJK, 2004), p. 44
What are some cultural messages that encourage us to abandon biblical teaching on sex? What are some of the consequences of acting on those messages?
How does Jesus' commentary on the seventh commandment (see Matthew 5:27-32) counsel us to act differently?
How does Paul echo Jesus' teaching in Colossians 3:1-17?
The answer to this catechism question provides an interesting way to look at the eighth commandment, which prohibits stealing. We are told not only to avoid taking from another person without his/her permission, but also to be sure to give when it would benefit someone. Why do you think the authors of the catechism frame the prohibition on stealing this way?
How does the parable of the Good Samaritan (see Luke 10:25-37) illustrate both ways of understanding stealing?
