CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 937–941

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.
