From St Augustine:
Scattered about the entire earth, your mother of the Church is tormented by the assaults of error. She is also afflicted by the laziness and indifference of so many of the children she carries around in her bosom as well as by the sight of so many of her members growing cold, while she becomes less able to help her little ones. Who then will give her the necessary help she cries for if not other children and other members to whose number you belong?
