Amid protests by various groups against this Saturday's Pink Dot event, the National Council of Churches of Singapore issued a statement last night to all its members reiterating that homosexual and bisexual practices go against the teachings of the Bible.
But it does not condemn those who struggle with their sexual orientation or gender identity, it added.
The council, which represents more than half of the 500 or so churches here, urged members of the Christian community to "always act with grace and restraint should they engage with the lesbian, gay, bisexual and transgender (LGBT) community over the coming event".
It noted that current discourse on the issue has been "prompted by the intention of the LGBT community to hold a Pink Dot picnic" this Saturday, and that it has "generated strong reactions among Singaporeans, including Christians".
Therefore, it was issuing the statement to its members "in the interest of clearing up the matter concerning human sexuality for members of the Christian public who may be confused".
The statement comes days after Archibishop William Goh, in a similar vein last weekend, maintained that the family unit comprises a father, mother and children. His statement, read out at 30 Catholic churches, also said LGBT sexual relationships are "not in accordance with the plan of God".
These responses come in the lead up to the Pink Dot gathering, which supports equality for the LGBT community in Singapore.
A campaign started by an Islamic religious teacher has called for people to wear white to protest the event, which takes place on the eve of the Islamic holy month of Ramadan. It has received the backing of various Christian and Muslim groups.
