The grand distinguishing characteristic of this class of Christians is their belief in the final holiness and happiness of the whole human family. Some of them believe that all punishment for sin is endured in the present state of existence, while others believe it extends into the future life; but all agree that it is administered in a spirit of kindness, is intended for the good of those who experience it, and that it will finally terminate, and be succeeded by a state of perfect and endless holiness and happiness.
