The apostolate is every activity of the Mystical Body that aims to spread the Kingdom of Christ over all the earth (CCC 863-864). Both the hierarchy and the laity are called to participate in this mission according to their proper state (CCC 863, 900).
Universal Call
Every Christian, by virtue of their Baptism and Confirmation, is called to be an apostle—one who is 'sent' to bear witness to the Gospel in their daily life (CCC 863-865).
