935 To proclaim the faith and to plant his reign, Christ sends his apostles and their successors.
He gives them a share in his own mission. From him they receive the power to act in his person.
936 The Lord made St. Peter the visible foundation of his Church. He entrusted the keys of the
Church to him. The bishop of the Church of Rome, successor to St. Peter, is “head of the college
of bishops, the Vicar of Christ and Pastor of the universal Church on earth” (CIC, can. 331).
937 The Pope enjoys, by divine institution, “supreme, full, immediate, and universal power in
the care of souls” (CD 2).
938 The Bishops, established by the Holy Spirit, succeed the apostles. They are “the visible
source and foundation of unity in their own particular Churches” (LG 23).
939 Helped by the priests, their co-workers, and by the deacons, the bishops have the duty of
authentically teaching the faith, celebrating divine worship, above all the Eucharist, and guiding
their Churches as true pastors. Their responsibility also includes concern for all the Churches,
with and under the Pope.
940 “The characteristic of the lay state being a life led in the midst of the world and of secular
affairs, lay people are called by God to make of their apostolate, through the vigor of their
Christian spirit, a leaven in the world” (AA 2 § 2).
941 Lay people share in Christ’s priesthood: ever more united with him, they exhibit the grace
of Baptism and Confirmation in all dimensions of their personal, family, social, and ecclesial
lives, and so fulfill the call to holiness addressed to all the baptized.
942 By virtue of their prophetic mission, lay people “are called... to be witnesses to Christ in all
circumstances and at the very heart of the community of mankind” (GS 43 § 4).”
943 By virtue of their kingly mission, lay people have the power to uproot the rule of sin
within themselves and in the world, by their self-denial and holiness of life (cf. LG 36).
944 The life consecrated to God is characterized by the public profession of the evangelical
counsels of poverty, chastity, and obedience, in a stable state of life recognized by the Church.
945 Already destined for him through Baptism, the person who surrenders himself to the God
he loves above all else thereby consecrates himself more intimately to God’s service and to the
good of the whole Church.”
The Communion of Saints (In Brief 960-962)
960 The Church is a “communion of saints”: this expression refers first to the “holy things”
(sancta), above all the Eucharist, by which “the unity of believers, who form one body in Christ,
is both represented and brought about” (LG 3).
