Mormons generally donate money for two purposes—supporting the Church and providing for the poor. The first type of donation is tithing (10% of one's income), which is used to build churches and temples, print church manuals and hymn books, support the Church's educational institutions, and otherwise care for the needs of the Lord’s church. One unique thing about the Mormon Church and almsgiving is that Mormon leaders do not receive any money from the members of their congregation. Nearly all church leaders work on a volunteer basis and are not paid. The First Presidency and Quorum of the Twelve Apostles receive a modest income, and Mission Presidents receive some modest support during their three years of service in the mission field.
