A GROUP of Catholic nuns began a well-funded bus tour yesterday to campaign for more federal monies for the poor. While the most vulnerable members of society suffer the ravages of the sexual revolution and the loss of the sacred, these leftist sisters of mercy insist what people need most is government charity. Confirming the image of America’s religious sisters as political hucksters, these nuns are committed to a desacralized society. Pray for these foolish revolutionaries. They know not what they do. Their minds have been steeped in Kumbaya.
