Hallmark cards celebrating the marriages of gay and lesbian couples were removed from the shelves of the Brigham Young University (BYU) bookstore on Tuesday.

After an image of the cards, which read “Mr. and Mr.” and “Mrs. and Mrs.,” being sold inside the BYU Store was posted online, staff members quickly removed the cards.

The BYU Store responded to an item about the cards in ProvoBuzz.com: “Thanks for letting us know! Hallmark stocks the shelves and sometimes they get by us.”

Carri Jenkins, a spokeswoman for BYU, referred the AP to the school's honor code, which prohibits “all forms of physical intimacy that give expression to homosexual feelings,” when asked why the cards were removed.

BYU is owned by the Church of Jesus Christ of Latter-day Saints (the Mormons), which is opposed to marriage equality and worked for passage of Proposition 8, California's now-defunct constitutional amendment that excluded gay couples from marriage.
