Mitt Romney's tax returns reveal that the Republican presidential candidate does something fewer Americans are doing these days: He tithes.
Romney's 2009 and 2010 tax returns, released last week, show that he and his wife, Ann, gave 10 percent of their income, about $4.1 million, to the Church of Jesus Christ of Latter-day Saints. The couple reported income of about $43 million for the two years.
LDS church members must tithe to participate in temple rituals. Nearly 80 percent of Mormons tithe, a poll released this month by the Pew Forum on Religion and Public Life shows.
While tithing among Mormons is high, it is at an all-time low -- less than 3 percent -- among many faith groups, according to an October report by Empty Tomb, a Christian research organization. The theology behind tithing is also being questioned, with many saying the mandate to contribute 10 percent is not biblical.
Tithing has its roots in the Old Testament -- "Bring all the tithes to the storehouse," from the book of Malachi -- and means one-tenth of income.
"The New Testament says a Christian is saved under grace, and it does not teach tithing," said Russell Kelly who argues against it on his website (www.tithing-russkelly.com). "A lot of people would rather stay home than go to church and hear about it. All it does is make them feel as if they're cursed for not giving 10 percent."
About 58 percent of evangelical leaders don't believe that the Christian Bible requires tithing, according to a study in April conducted by the National Association of Evangelicals. They do, however, believe Christians should give generously.
Kelly and others promote "sacrificial giving" -- giving in proportion to what God has given them.
