Here's a section from Aaronic Priesthood Manual 3: Lesson 31, Choosing an Eternal Companion.
What characteristics of young women are socially and spiritually appealing to you?
Write the young men’s answers on the chalkboard, such as—
1. Is unselfish.
2. Shows respect for me.
3. Has initiative.
4. Is considerate of others.
5. Shows patience in stressful situations.
6. Is an active Church member.
7. Has a testimony of the gospel and obeys the commandments.
8. Maintains a healthy outlook toward life.
9. Possesses values and goals similar to mine.
Ask each young man to select what he thinks are the three most important attributes on the chalkboard. Take a vote to determine which areas the young men consider most important. Discuss why they voted the way they did.
Quotation and discussion
Compare the results of the vote with the following statement by President Spencer W. Kimball. Have a young man read it.
“We recommend that people marry those who are of the same racial background generally, and of somewhat the same economic and social and educational background (some of those are not an absolute necessity, but preferred), and above all, the same religious background, without question” (“Marriage and Divorce,” in 1976 Devotional Speeches of the Year [Provo: Brigham Young University Press, 1977], p. 144).
Interesting that this same quote is not in the Young Women's Manual in the chapter "Preparing to Become and Eternal Companion." I think this was missed by the correlation committee. It seems to me that in this day and age the people making the manuals would be scrubbing these old outdated teachings and opinions from old prophets from the lesson manuals. It's not in the YW manual, and I would bet that it was supposed to be removed from the YM manual and someone missed it.
