Inside the Latter-day Saints' Washington, D.C. temple

Its spires leap nearly 300 feet into the sky, and at their pinnacle, a two-ton, gold-covered angel issues a clarion call to the heavens. The Church of Jesus Christ of Latter-day Saints' Washington, D.C. Temple is clad in white Alabama marble, matching other monuments around the nation's capital. But for decades it has posed something of a mystery to the millions who stream by on D.C.'s Beltway, with some even comparing it to "The Land of Oz."

When asked what church members think when they hear that, Todd Christofferson replied, "We smile! But it's one of the reasons we have this open house. We won't get everybody who comes around the corner on the Beltway, but I hope more and more will see it as something much, much more than Oz."

Christofferson and David Bednar are two of the twelve apostles, or highest-ranking elders, of the Church of Jesus Christ of Latter-day Saints. They traveled from Utah to bring CBS News' Ed O'Keefe inside the church's hallowed Washington, D.C. temple – a place normally off-limits to all but members of the faith.
