The Vatican Secretariat of State has raised concerns about the bill

This is the first known instance of the Vatican using official diplomatic channels to oppose legislation in Italy; although given that it was publicized through a leak to the press and not an official statement, it is possible it has happened before. It is an odd time for the Holy See to brandish such a weapon. The world is observing Pride Month, and Italy is set to host a series of Pride parades this weekend, which organizers now say will protest the Vatican action. In addition, the Catholic Church in Italy has usually fared poorly when opposing Italian laws.

Gay rights group Stonewall also welcomed the booklet, but denied direct involvement

Critics say the document fails to adequately explain Church teaching on sexuality

We should recognise it as a homophobic killing and renew our commitment to upholding the rule of law

Engaging the Church's most vocal critics is risky, but ultimately worthwhile

It is not just 'bible-thumping Christians' who oppose the change
