(CNN) - A holiday card that falsely claims to be from "the Romney family" and highlights Mitt Romney's Mormon faith was anonymously sent to Republican mailboxes across South Carolina earlier this week.
The source of the card is unknown.
The mailer, which says it is "Paid for by the Boston Massachusetts Temple," displays a quote from Mormon apostle Orson Pratt saying that God had multiple wives:
"We have now clearly shown that God the father had a plurality of wives, one or more being eternity by whom he begat our spirits as well as the spirit of Jesus, his first born, and another being upon the earth by whom he begat the tabernacle of Jesus, as his only begotten in this world," the quote reads.
A copy of the glossy brochure obtained by CNN offers holiday wishes from "the Romney family": "We wish you and your family a happy holiday season and a joyful New Year," it says.
The card focuses on the Republican presidential candidate's home state of Massachusetts, displaying a photo of the Mormon Temple in Boston as well as a snowy photo of the Public Garden in Boston.
The mailing also quotes from the first Book of Nephi, part of the book of Mormon, in which the Virgin Mary is described as "exceedingly fair and white."
Romney spokesman Will Holley condemned the card.
"It is sad and unfortunate that this kind of deception and trickery has been employed," Holley said. "There is absolutely no place for it in American politics."
