The former papal ambassador to France is to face trial on sexual assault charges in November, the Paris prosecutor's office said on Thursday.
The Vatican had lifted the diplomatic immunity of then papal nuncio Luigi Ventura last year to allow French authorities to investigate allegations against him.
The envoy was accused in January last year of repeatedly touching a young male city official during a function at the Paris city hall. Further men later came forward with similar allegations.
In December, Pope Francis accepted Ventura's resignation.
The trial is due to start on November 10, the prosecutor's office said.
The Catholic Church has been in turmoil for years over worldwide reports of clerical sex abuse, and the Vatican has repeatedly pledged to tackle the issue with reforms.
France's most senior Catholic churchman, Cardinal Philippe Barbarin, resigned in March after an appeals court acquitted him of failing to report abuse allegations against a priest in his diocese.
The priest in question was later jailed for five years for repeated sexual assaults on boys throughout the 1980s, when he was chaplain to a scout group. The offences took place long before Barbarin was appointed archbishop.
