Pope Francis has said he is willing to create a commission to study whether women can be deacons in the Catholic Church, signalling an openness to letting women serve in ordained ministry currently reserved to men.
Francis agreed to the proposal during a closed-door meeting with some 900 superiors of women's religious orders.
Deacons are ordained ministers, but are not priests, though they can perform many of the same functions as priests: preside at weddings, baptisms and funerals, and preach.
They cannot, however, celebrate Mass.
Currently, married men - who are also mostly excluded from the Roman Catholic priesthood - can serve as deacons.
Women cannot, however, though historians say women served as deacons in the early Church.
The Pope in no way signalled during a 75-minute conversation with the sisters that the church's longstanding prohibition on ordaining women priests will change.
But asked during a question-and-answer session if he would be willing to create a commission to study whether women could serve as deacons, Francis said he was open to the idea, according to the National Catholic Reporter and Catholic News Service, which were in the audience hall.
The publications quoted Francis as saying: "I accept. It would be useful for the church to clarify this question. I agree."
Francis noted that the deaconesses of the early church weren't ordained as they are today, but said he would ask the Congregation for the Doctrine of the Faith to report back on studies that have been done on the issue.
Francis also said he would ask another Vatican office that is in charge of the liturgy to report back on why women aren't allowed to give a homily at Mass.
