Over 10,000 pilgrims, many of them youth from schools around the nation, are expected to gather in the Basilica of the National Shrine of the Immaculate Conception to pray for an end to abortion at the Opening Mass of the National Prayer Vigil for Life, Thursday, January 24, at 6:30 p.m., the eve of the annual March for Life. The vigil coincides with the 40th anniversary of the Supreme Court’s Roe v. Wade decision on January 22, 1973, which legalized abortion nationwide. Since the decision was handed down, an estimated 55 million abortions have been legally performed in the United States.
