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

From The Catechism of the Catholic Church

863
The whole Church is apostolic, in that she remains, through the successors of
St. Peter and the other apostles, in communion of faith and life with her
origin: and in that she is “sent out” into the whole world. All
members of the Church share in this mission, though in various ways. “The
Christian vocation is, of its nature, a vocation to the apostolate as
well.” Indeed, we call an apostolate “every activity of the Mystical
Body” that aims “to spread the Kingdom of Christ over all the earth.”³⁷⁷
