Couples can chose between "one of several different wedding ceremonies with varying degrees of formality. Each of these ceremonies includes traditional vows of loyalty and devotion," according to the website.
In one version of the ceremony, called the "Double Ring," a minister tells the couple "that through your love together, with your agreement upon its reality, and by your communication of these two beautiful truths, you have completed the ARC Triangle, and thereby consummated the only true marriage."
ARC refers to "affinity, reality and communication," according to the Church.
Before Cruise and Holmes were married, Holmes delivered the couple's daughter in a "silent birth" in which no one around the mother talks during the delivery.
"It's basically just respecting the mother, you know, and helping to be quiet -- not the mother. The mother makes as much noise ... you know, she's going through it," Cruise told ABC News in 2006. "But why have other people make noise? You know, you want that area very calm and to make it very special."
