In a new pastoral letter released Feb. 9, Archbishop William E. Lori of Baltimore takes the occasion of the nation’s 250th anniversary to address “a moment of grace and responsibility.” Catholic Review Editor Christopher Gunty talked with the archbishop about the motivation for the letter, which is subtitled, “Toward a Renewed Political Culture.” Archbishop Lori notes in the interview that the extreme polarization of the current political climate is painfully evident and that we need to find common ground to work for human dignity.
