Currently, there are two types of marriage ceremony in Scotland - civil and religious.
Since June 2005, celebrants belonging to the Humanist Society of Scotland have been authorised on a temporary basis to solemnise marriage.
Such marriages have been classed as "religious" under marriage law, despite the beliefs of such organisations being non-religious - a situation the draft Bill aims to alter.
Under the proposals, the arrangements for authorising belief celebrants would be along the same lines as those for authorising religious celebrants. The proposals also set out the arrangements for authorising belief celebrants to solemnise same-sex marriage.
"The system will be opt-in and bodies and celebrants will have to choose to take part in same-sex ceremonies," the document states.
