The high temperature in Santo Domingo, the capital of the Dominican Republic, was 86 degrees on Jan. 21, during the feast of Our Lady of Altagracia (High Grace), the preeminent Marian devotion in the Caribbean nation. Meanwhile, in Brooklyn, it was 16 degrees that same evening when hundreds of Catholics from at least a dozen parishes filled the Co-Cathedral of St. Joseph in Prospect Heights to observe the feast with a special Mass.
