+Mt 28: 16-20
The eleven disciples went to Galilee, to the mountain to which Jesus had ordered them.
When they saw him, they worshiped, but they doubted.
Then Jesus approached and said to them, “All power in heaven and on earth has been given to me.
Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the holy Spirit,
teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the age.”

THE CHURCH IS APOSTOLIC
857 The Church is apostolic because she is founded on the apostles, in three ways:
– she was and remains built on “the foundation of the Apostles,” the witnesses chosen and sent on mission by Christ himself;
– with the help of the Spirit dwelling in her, the Church keeps and hands on the teaching, the “good deposit,” the salutary words she has heard from the apostles;
– she continues to be taught, sanctified, and guided by the apostles until Christ’s return, through their successors in pastoral office: the college of bishops, “assisted by priests, in union with the successor of Peter, the Church’s supreme pastor”:
You are the eternal Shepherd
who never leaves his flock untended.
Through the apostles
you watch over us and protect us always.
You made them shepherds of the flock
to share in the work of your Son. . . .
