The pictures come from tonight's Easter Vigil ceremonies in St. Patrick's Cathedral, NYC and you'll note that they are wearing Roman style vestments for the occasion. The deacon wore a matching dalmatic from the set.
This particular vestment was commissioned by a turn of the century New York Cardinal, Cardinal John Farley. The vestments depict embroidered scenes of the Passion, Death and Resurrection of Christ, set against a gold background.
Thanks to the individual who sent these in to us.
