A Baptist pastor in the southern states of the US is trying to get Christians to shun same-sex weddings - even of their own children - claiming that attendance justifies the "sinfulness of homosexuality".
The problem for Rev Al Mohler, the president of the Southern Baptist Theological Seminary in Louisville, Kentucky, is that not many people seem to be listening.
In a new book called We Cannot Be Silent, the right-wing pastor claims that same-sex marriages are sinful and even urges transgender people to consult their church leaders about "reverting".
According to the Huffington Post, the controversial Mohler has even claimed in the past that the Pope holds an "un-Biblical" office and has stated that Christians shouldn't practice yoga.
At some point, attendance will involve congratulating the couple for their union. If you can’t congratulate the couple, how can you attend?
Despite Mohler's calls, Think Progress has charted the growing movement of pro-LGBT Christians in the US who are rejecting his hateful message.
The Presbyterian Church (USA), Episcopal Church, Evangelical Lutheran Church in America, and United Church of Christ (UCC) all now marry those in the LGBT community and a recent study showed that the majority of most religious groups in the US support equal marriage.
Perhaps Rev. Mohler is worried that if parents attend such a wedding, all they will see is a sacred and holy commitment being made between two people and an invitation to God to be present in the couple’s relationship — as Christian as any marriage could be.
