The concept of a united family that lives and progresses forever is at the core of Latter-day Saint doctrine, and Mormons place a high importance on family life. Many Mormons hold weekly Family Home Evenings, in which an evening is set aside for family bonding, study, prayer and other activities they consider to be wholesome. Latter-day Saint fathers who hold the priesthood typically name and bless their children shortly after birth to formally give the child a name. Mormon parents hope and pray that their children will gain testimonies of the "gospel" so they can grow up and marry in temples.
