Sikhism
The Sikh holy book, the Guru Granth Sahib, does not explicitly mention homosexuality. The Guru Granth Sahib is seen as the spiritual authority on all Sikh matters.
Some modern Sikh leaders have condemned homosexuality. Giani Joginder Singh Vedanti of the temporal Sikh authority (Akal Takht), has condemned homosexuality while reminding visiting Sikh-Canadian Members of Parliament (MPs) of their religious duty to oppose same-sex marriage. The Sikh religious body, the Akal Takht, has issued an edict condemning gay marriage.
Other Sikhs point out that Sikhism does not condemn homosexuality or gay marriage reminding them that the Guru Granth Sahib, leaves this as a matter of personal conscience.
