There's not been lots of details revealed about the recent Ad Limina of New England's 18 bishops. That may be because most of the meetings are private affairs between a bishop --or a group of bishops-- and the Pope and his 12 key Vatican collaborators. The pilgrimage in Rome happened 3-9 November. The two New England Metropolitans, Cardinal O'Malley and Archbishop Mansell, led the bishops with the coordinating help of Bishop Evans.
There are things that are becoming more known because of the generosity of the bishops speaking about their experiences and their concerns.
Several stories of the recent Roman pilgrimage are noted here:
Boston's Cardinal Sean O'Malley, OFM Cap: "Together with the Holy Father"
Burlington's Bishop Salvatore Matano: "US ad limina visits in focus"
A widely circulated CNS article: "Ad Limina visit highlights religious freedom, evangelization"
