Pope Francis has backed a doctrinal report drawn up under his predecessor Benedict XVI that accused the largest group of nuns in the United States of holding "radical feminist" views, the Vatican said in a statement on Monday.
The new pope has "reaffirmed the findings of the assessment and the program of reform" for the Leadership Conference of Women Religious (LCWR), which represents around 45,000 US nuns and is known for its social work, the Vatican said.
The statement said the head of the Vatican's Congregation for the Doctrine of the Faith, Gerhard Ludwig Mueller, met representatives of the LCWR in the Vatican on Monday in an attempt to smooth over differences.
Mueller thanked the group for its work in "many schools, hospitals, and institutions of support for the poor" in the US, the statement said.
But he also emphasised the need for the group to cooperate with US bishops and said LCWR was legally "under the direction of the Holy See".
In a brief statement, LCWR said only that the talks had been "open and frank".
"We pray that these conversations may bear fruit for the good of the Church," it said.
The Vatican report issued in 2012 following a three-year investigation pointed to "serious doctrinal problems" and "unacceptable positions".
It appointed the Archbishop of Seattle, Peter Sartain, to ensure the group toe the line.
The report accused LCWR members of "dissent" with Church teachings against homosexuality and said they were pursuing "radical feminist themes".
It condemned LCWR for being "silent on the right to life from conception to natural death".
The report also said a position stated by LCWR in 1977 against the ordination of priests as a male prerogative "has never been corrected".
