Gregory said in an article Monday in a Catholic newspaper, the Georgia Bulletin, that the "world and church have changed." He said that if church bodies decide it is appropriate he will sell the mansion in Atlanta's upmarket Buckhead neighborhood.
“I am disappointed that, while my advisers and I were able to justify this project fiscally, logistically and practically, I personally failed to project the cost in terms of my own integrity and pastoral credibility with the people of God of north and central Georgia,” Gregory wrote.
Pope Francis, who was elected last year, is known for his modest lifestyle. Francis has been living in a guest house at the Vatican instead of the papal apartments.
A few days ago, Francis accepted the resignation of Franz-Peter Tebartz-van Elst as bishop of Limburg. He had been nicknamed the "bishop of bling" in Germany because of his lavish spending.
The new episcopal mansion in Atlanta was built on property left to the church by Joseph Mitchell, nephew of "Gone with the Wind" author Margaret Mitchell. Mitchell also left the church $15 million.
The archdiocese decided to tear down Mitchell's house, replacing it with a residence of more than 6,000 square feet. The archbishop's former residence is being converted into a rectory for Christ the King Parish.
