Pope Francis has named three women, two nuns and a lay woman, to a previously all-male committee that advises him in selecting the world's bishops, the Vatican said.
He had disclosed the decision in an interview with Reuters earlier this month, explaining he wanted to give women more senior and influential positions in the Holy See.
The three women are sister Raffaella Petrini, an Italian who is currently the deputy governor of the Vatican City, French nun Yvonne Reungoat, a former superior general of a religious order, and Argentine lay woman Maria Lia Zervino, president of the World Union of Catholic Women's Organizations, UMOFC.
The three women were among 14 people appointed to the Dicastery for Bishops, which vets candidates and advises the pope on which priests should become bishops.
The other 11 appointed were cardinals, bishops and priests.
Terms last for five years. Before today's announcement of the 14 names, there were more than 20 members.
The total fluctuates as terms expire but usually the committee numbers between about 25-30.
The process starts locally where bishops suggest to archbishops the names of priests they think would make good bishops.
The list then goes to the Vatican nuncio, or ambassador, in a country, who further investigates the person and sends his recommendations to the Vatican.
The members of the committee, who come from around the world, meet in Rome about twice a month and send their recommendations to the pope, who makes the final decision.
"This way, things are opening up a bit," Pope Francis said earlier this month.
Apart from Sr Petrini, who as deputy governor is the most powerful woman in the world's smallest state, Pope Francis has already named a number of women, both nuns and lay women, to Vatican departments.
Last year, he named Italian nun Sister Alessandra Smerilli to the number two position in the Vatican's development office, which deals with justice and peace issues.
In addition, Pope Francis has named Nathalie Becquart, a French member of the Xaviere Missionary Sisters, as co-under secretary of the Synod of Bishops, which prepares major meetings of world bishops held every few years.
Lay women already holding top jobs in the Vatican include Barbara Jatta, the first female director of the Vatican Museums, and Cristiane Murray, the deputy director of the Vatican Press Office.
Both were appointed by Pope Francis.
