A poll by YouGov shows a majority of Scotland’s population support marriage rights for same-sex couples.
56% of Scots support the legislation going through Holyrood; 35% are opposed, while 8% are unsure.
The findings have been welcomed by equal marriage campaigners who say MSPs should “take heart” from the level of support among the public.
The Marriage and Civil Partnerships (Scotland) Bill passed its first Stage One vote on 20 November.
It will now go back to the Equal Opportunities Committee for a more detailed “line-by-line” scrutiny; amendments to the bill are likely to be made by the committee.
If the bill passes at Stage Two, the Stage Three vote is likely to happen around February.
