Paragraph 3. THE CHURCH IS ONE, HOLY, CATHOLIC, AND APOSTOLIC

From The Catechism of the Catholic Church

817

there arose certain rifts, which the Apostle strongly censures as damnable. But
in subsequent centuries much more serious dissensions appeared and large
communities became separated from full communion with the Catholic Church – for
which, often enough, men of both sides were to blame.”²⁶⁹ The
ruptures that wound the unity of Christ’s Body – here we must distinguish
heresy, apostasy, and schism²⁷⁰ – do not occur without human sin:
