You seem to think that it must be one or the other. Both are necessary. There is no real sanctifying piety unless it inspires a religion of pity. If there is no pity, there is no piety and no sanctity, but self-deception and hypocrisy. At the same time, banish sanctifying piety, and mere pity or kindness is not religion. It may be philanthropy or humanitarianism, but it is not religion. Religion essentially means that we must love God, and that our love for God must overflow upon other children of God.
