Matthew 5 opens the Sermon on the Mount, which runs through Matthew 7. Luke 6 gives a shorter version on a level place, in 6:17. It comes right after Jesus prays all night and chooses the Twelve, in 6:12–16. The sermon starts with the Beatitudes in Matthew 5:3–12. Luke pairs them with four matching woes, in Luke 6:20–26. Then come salt and light in Matthew 5:13–16. Next are six contrasts that begin “Ye have heard that it was said… But I say unto you.” That’s 5:21–47. They cover anger, lust, divorce, oaths, retaliation and enemies. Each one takes an old command about actions and aims it at the heart. The chapter ends with “Be ye therefore perfect,” in 5:48.
Here are a few study helps your youth will love. Look at the footnote on Matthew 5:22. The Joseph Smith Translation and 3 Nephi 12:22 both leave out “without a cause.” So the Savior’s standard on anger is higher than it first looks. Matthew 5:23–24 says to be reconciled before you bring your gift to the altar. That speaks right to priests who bless the sacrament. The Book of Mormon version of the sermon adds important words: “blessed are the poor in spirit who come unto me,” in 3 Nephi 12:3. And after His Resurrection, the Savior says “perfect even as I, or your Father,” in 3 Nephi 12:48. The footnote on Matthew 5:48 explains that the Greek word means complete, finished, fully developed.
For 16- to 18-year-olds, this chapter lands right on top of perfectionism. Think college applications, scholarships, mission standards, sports, and a phone full of other people’s highlight reels. Jesus’s Beatitudes flip the world’s idea of “blessed.” Luke’s last woe stings in a world of likes and follower counts: “when all men shall speak well of you,” in 6:26. Jeffrey R. Holland gave a talk in October 2017 called “Be Ye Therefore Perfect—Eventually.” He says teenagers and missionaries often tell him they’re not good enough. He teaches that perfection is a gift received through Christ over time. See Moroni 10:32. Share it with confidence.
Handle Matthew 5:27–28 gently and simply. The Savior teaches that purity begins in our thoughts. “Your Body Is Sacred” in For the Strength of Youth: A Guide for Making Choices is a great companion. Don’t single anyone out. Keep the focus on hope and repentance. If a youth comes to you privately, listen warmly and point them to their parents and bishop. Shame is never the Savior’s tool.
