John Donne on Catholicity

The church is Catholic, universal, so are all her actions; all that she does belongs to all. When she baptizes a child, that action concerns me; for that child is thereby connected to that head which is my head too, and ingrafted into that body whereof I am a member. And when she buries a man, that action concerns me: all mankind is of one author, and is one volume; when one man dies, one chapter is not torn out of the book, but translated into a better language; and every chapter must be so translated; God employs several translators; some pieces are translated by age, some by sickness, some by war, some by justice; but God's hand is in every translation, and his hand shall bind up all our scattered leaves again, for that library where every book shall lie open to one another....No man is an island, entire of itself; every man is a piece of the continent, a part of the main....any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bell tolls; it tolls for thee. ~ John Donne
