Gay rights activist Peter Tatchell praised Liberal Judaism for its same-sex commitment ceremonies when he addressed a Friday night dinner of the Jewish Gay and Lesbian Group in central London.
Mr Tatchell, co-founder of OutRage, also told the 50 diners that the UK had become one of the most progressive societies in the Western world in terms of gay rights.
Rabbis Judith Levitt, Mark Solomon and Ariel Friedlander were also among the guests.
JGLG vice-president Ed Teeger said Mr Tatchell had been "inspirational. He has done such good work for gay rights and for human rights.
"One thing he mentioned was that he hoped there could one day be full civil partnership ceremonies in synagogues."
The JGLG celebrates its 40th anniversary next month.
