You can always count on James Carroll to offer an insightful perspective. His latest column in the Boston Globe begins with these words:The single most eloquent expression of the Catholic Church’s Second Vatican Council in 1965 was a preposition - the word “in.’’ The title of the council declaration “The Church in the Modern World’’ could readily have been expected to be “The Church against the Modern World,’’ reiterating a long-held opposition. Or, a little more positively, it might have been “The Church and the Modern World,’’ defining a gulf between the sacred and the secular that devalues both realms. But instead, the council fathers stated their conviction that the church, neither above nor detached, is integrally a part of the contemporary human condition - happily so. The decree’s Latin title “Gaudium et Spes’’ translates as “Joy and Hope’’ - an even stronger signal of the council’s affirming mind-set.
