Malta is set to pass a law legalizing same-sex marriage when its Parliament votes on Wednesday.
The vote signals the latest in shifting attitudes that have swept across the staunchly Catholic country since the 2011 referendum to legalize divorce.
Since then, the country has introduced civil unions and last year became the first European state to ban “gay cure” therapy.
Last month, Prime Minister Joseph Muscat said gay marriage would be one of his priorities after he won a snap election.
“Malta wants to keep leading on LGBT issues and civil liberties, to serve as a model for the rest of the world,” Muscat told the BBC.
The changes are part of what the Maltese government hopes will be a modernization of marriage that will also allow gay couples to adopt children.
In the bill, references to “wife,” “husband,” “mother” and “father” all scrapped in preference of gender-neutral terms such as “parent” and “spouse.”
Evelyne Paradis, executive director in the European region of the International Lesbian, Gay, Bisexual, Trans and Intersex Association, said the changes were hugely welcome.
“The new law is the missing piece in the puzzle when it comes to family rights in Malta,” she said.
“The use of gender-neutral terms means that everyone is equal and it is much more inclusive, particularly when it comes to the trans community.”
While the measure is expected to pass, some lawmakers have said they would vote against it.
Nationalist lawmaker Edwin Vassallo said he would be opposing the bill because it was “morally unacceptable.” He accused the Prime Minister of “causing social destruction which goes against the natural laws.”
Last week, Germany moved to become the latest European nation to legalize same-sex marriage. The Netherlands was the first country to take that step in 2001.
Since then, more than 20 other nations have followed suit, including Spain, Canada, Argentina, France, the United Kingdom, Germany, Ireland and the United States.
