The man at a centre of a viral video insists that footage of him denouncing homosexuality was not staged.

Andrew Caldwell maintains that he has been delivered from same-sex attractions, and shared more of his testimony in a recent Facebook post.

The video was recorded at the Church of God In Christ's 107th Holy Convocation in St. Louis last weekend. Caldwell approached the altar, and told Pastor Brandon Porter that he was no longer gay.

"I'm not gay no more; I've been delivered!" Caldwell shouted. "I don't like mens [sic] no more. I said I like women! Women, women, women, women!

"I said women! I'm not gay!" he continued. "I will not date a man. I will not carry a purse. I will not put on make-up. I will, I will, love a women [sic]."

Caldwell then began dancing.

Many have mocked and questioned the authenticity of Caldwell's conversion from homosexuality to heterosexuality. The St. Louis man explained in a Facebook post that he had been struggling with his sexual orientation and seeking the Lord prior to attending the Convocation.

"As a child, I was raped by a member of my own family," he wrote. "At that time I did not think of it as abuse. I kind of enjoyed it. I kept it to myself, not realising how it had changed me. Growing up wasn't a pleasant experience. I was harassed, heckled, and ridiculed by classmates.

"Being fairly attractive as a young man, it was not difficult for me to get involved with other men. I have dated athletes, ministers, and celebrities.

"After joining my present church, it came to me that this lifestyle was not right. It seemed that the more I tried to quit on my own, the more intense was the temptation. All last week I fasted and prayed.

"On this past Saturday at the Convocation, there was an alter call. I came forward and offered my testimony. It was unscripted. Not only do I hope for my own deliverance but for the deliverance of others who may be struggling with their own issues.

"To my doubting detractors, I pray for you. To my supporters, I am grateful for your support and prayers."
