Many priests and seminarians from the Diocese of Rockville Centre were part of the opening Mass of the National Prayer Vigil for Life at the Basilica of the National Shrine of the Immaculate Conception in Washington Jan. 21.

The all-night vigil is held before the annual March for Life, which this year marked the 43rd anniversary of the Supreme Court’s Roe v. Wade decision that legalized abortion across the nation. Photographer Gregory A. Shemitz captured the images below of the event.
