BBC News reports that Scotland will bring forth a bill which could introduce gay marriage by the start of 2015.
Scotland's deputy first minister, Nicola Sturgeon, said: "We are committed to a Scotland that is fair and equal and that is why we intend to proceed with plans to allow same-sex marriage and religious ceremonies for civil partnerships - we believe that this is the right thing to do.
She went on: "The Scottish government has already made clear that no religious body will be compelled to conduct same-sex marriages and we reiterate that today. Such protection is provided for under existing equality laws.
"However, our view is that to give certainty on protection for individual celebrants taking a different view from a religious body that does agree to conduct same-sex marriages, an amendment will be required to the UK Equality Act."
The Church of Scotland, which will report on its own investigation of the issue in May 2013, expressed concern the government was rushing ahead with its plans.
The Rev Alan Hamilton, convener of the Church of Scotland legal questions committee, said: "We are acutely aware that opinions differ among our own members and that many people are anxious and hurt in the current situation.
"We believe homophobia to be sinful and we reaffirm our strong pastoral commitment to all people in Scotland, regardless of sexual orientation or beliefs."
He added: "We are concerned the government will legislate without being able to effectively protect religious bodies or their ministers whose beliefs prevent them from celebrating civil-partnerships or same-sex marriages."
