#GraceBibleChurch began trending on Twitter after South African TV personality and choreographer Somizi Mhlongo, who is openly gay, posted a video online saying a guest pastor at the Grace Bible Church in Soweto said being gay was "unnatural".
During the sermon Bishop Dag Heward-Mills, from Ghana, reportedly said: "There is nothing like [homosexuality] in nature."
Mhlongo said not only did he find the bishop's words hurtful, but he was disappointed when members of the congregation began to cheer.
Mhlongo's video caused a stir on Twitter with some users criticising the sermon and others supporting its message.

In the bible God talks about gay people and he also talks about judging people.
Church is a place where truths are spoken, even though it makes a lot of us uncomfortable#Gracebiblechurch— TRUST (@OrielBagani) January 22, 2017
If you don't agree w what's in the Bible, don't go to church. Pastors are here to preach the word, not to be popular #GraceBibleChurch— D-the-Diva (@DeeMoney_Diva) January 22, 2017
The church has said that it does not condone homophobia but acknowledges that many people share Bishop Heward-Mills' views.
Church pastor Rev Ezekiel Mathole told local media: "That was not the only thing that he was talking about.
"There are other people who are smokers who were offended because he also referred to a lot of lifestyle issues. And a lot of people who are having multiple partners were very offended."
