SALT LAKE CITY, UTAH — Republican candidate Mitt Romney has avoided mentioning his religion for much of the presidential campaign. But now he is emphasizing the close-knit nature of Mormon families and communities -- in the hope that it will help both him and his faith.

Iconic temples, a world-famous choir, and clean-cut missionaries sent worldwide by the Church of Jesus Christ of Latter-day Saints in Salt Lake City. But a visit to suburban Salt Lake City shows how members of the church, or Mormons, live out their faith at home.

Tami Larsen says family is sacred to Latter-Day Saints. "We believe that we will be a family forever not just until death," says Larsen.

The Larsens go every week to church, where even grownups attend Sunday school.

Mormons spend three hours in church every Sunday. They don't smoke, and don't drink coffee, tea or alcohol.

But there are rewards.

This is "Welfare Square" where food is packaged and sent to enormous "Bishops' storehouses." They in turn supply cashier-less supermarkets like this one for families in need.

Happy occasions can be celebrated at the main temple in Salt Lake City, or one of many others around the world.

"This is now the 139th temple," says the church elder William Walker.
