Alan Chambers, the president of Exodus International, has apologized to the gay community ahead of an upcoming television special.

Last year, Chambers began leading Exodus away from supporting therapies aimed at “curing” gay men and lesbians of their sexual orientation. At one point, Chambers starred in ads for the ministry along with the caption “Change is possible.”

Exodus now says it is emphasizing how gay Christians can manage their same-sex attractions. That is, the group continues to say that acting on those attractions is wrong.

Chambers has been criticized over the new policy from all sides. Ministries associated with the group have fled and some Christian conservatives called for his resignation. “Ex-gay” survivors said it wasn't enough.

For that last group, Chambers offered an apology in a blog post, saying that he had “hurt so many by failing to acknowledge the pain some affiliated with Exodus International caused, and by failing to share the whole truth about my own story.”

“Friends and critics alike have said it's not enough to simply change our message or website. I agree. I cannot simply move on and pretend that I have always been the friend that I long to be today. I understand why I am distrusted and why Exodus is hated.”

Chambers said that he was sorry “we promoted sexual orientation change efforts” and “didn't stand up to people publicly 'on my side' who called you names like sodomite – or worse.”

“I am sorry that I have communicated that you and your families are less than me and mine,” he added.

The apology comes ahead of an Our America episode titled God & Gays which includes an interview with Chambers. In a trailer for Thursday's show, Chambers is seen being confronted by “ex-gay” survivors. (The video is embedded on this page. Visit our video library for more videos.)
