Super Junior's Choi Siwon deleted an apology towards fans regarding previous anti-gay marriage tweets from his Twitter account.

The singer, a devout Christian, was embroiled in controversy after re-tweeting posts on Twitter denying the existence of same-sex marriage. After apologizing to his fans for insensitivity, Choi deleted all tweets relating to the incident.

Choi apologized after re-tweeting a post from conservative theologian John Piper that denied the case of Obergell V. Hodges, the U.S Supreme Court decision that reaffirmed the legality of same sex marriage in the United States.

As of September 13, all tweets relating to the incident have been deleted.

"I apologize for my inconsiderate choice to retweet Rev. Piper's tweet," wrote Choi on September 12, following his re-tweets from the day before. "The reason I echoed Rev. Piper's tweet was because I wished to voice a plurality of opinions. However, now I realize that my comments were hurtful to those I hold dearest; my fans and their families. I am truly sorry. My judgment was insensitive, thoughtless and ill-conceived. I will do my best to learn from my mistakes and reflect on my faith. I thank everyone for their support and understanding."

Piper's tweet that Choi shared stated, "Obergell is not constitutional; so-called gay marriage does not exist," and shared a link to an op-ed in support of Kim Davis.

Davis is a county clerk in Kentucky who made headlines for refuting the legality of same-sex marriage and denying marriage licenses to same sex couples.

Choi is a devout Christian and has continuously shared messages relating to his faith via Twitter and Instagram. He has re-tweeted posts from numerous Christian theologians in the past, including Rev. Piper.

Other quotes and articles from Rev. Piper, including quotes from the New Testament, remain on Siwon's Twitter account.

Choi has been vocal in the past about his views on homosexuality, including stating that he will not take an acting role that promotes gay relationships.

Choi has spoken in the past about being a Protestant missionary following the end of his career as a K-pop idol, and he has sung Christian songs on multiple occasions. Fans of Choi dubbed the nickname "Shisus" on the singer, combining his first name and that of Jesus.
