While admitting that the Pope's change in tone about gay priests is a "small step" that "does matter," Richard Lane from gay rights group Stonewall told ITV News there was much more to be done.
A next step would be a "strong statement against the harassment and persecution of gay people around the world [from the Pope]," Mr Lane said.
"He's got an unprecedented position at the Church with over a billion people so for him to make that statement would be incredibly significant."
