The second of the two pamphlets that The Church of Jesus Christ of Latter-Day Saints released in 2007 is called All Is Safely Gathered In: Family Finances. Here are the major points from the pamphlet (I've included the accompanying letter below):
Pay Tithes and Offerings
Successful family finances begin with the payment of an honest tithe and the giving of a generous fast offering. The Lord has promised to open the windows of heaven and pour out great blessings upon those who pay tithes and offerings faithfully (see Malachi 3:10).
Spending less money than you make is essential to your financial security. Avoid debt, with the exception of buying a modest home or paying for education or other vital needs. Save money to purchase what you need. If you are in debt, pay it off as quickly as possible.
Use A Budget
Keep a record of your expenditures. Record and review monthly income and expenses. Determine how to reduce what you spend for nonessentials. Use this information to establish a family budget. Plan what you will give as Church donations, how much you will save, and what you will spend for food, housing, utilities, transportation, clothing, insurance, and so on. Discipline yourself to live within your budget plan. (See the Budget Worksheet included with the pamphlet.)
Build A Reserve
Gradually build a financial reserve, and use it for emergencies only. If you save a little money regularly, you will be surprised how much accumulates over time.
Teach Family Members
Teach family members the principles of financial management. Involve them in creating a budget and setting family financial goals. Teach the principles of hard work, frugality, and saving. Stress the importance of obtaining as much education as possible.
Dear Brothers and Sisters:
Latter-day Saints have been counseled for many years to prepare for adversity by having a little money set aside. Doing so adds immeasurably to security and well-being. Every family has a responsibility to provide for its own needs to the extent possible.
We encourage you wherever you may live in the world to prepare for adversity by looking to the condition of your finances. We urge you to be modest in your expenditures; discipline yourselves in your purchases to avoid debt. Pay off debt as quickly as you can, and free yourselves from this bondage. Save a little money regularly to gradually build a financial reserve.
If you have paid your debts and have a financial reserve, even though it be small, you and your family will feel more secure and enjoy greater peace in your hearts.
May the Lord bless you in your family financial efforts.
