“Among the Christian faithful by divine institution there exist in the Church sacred ministers, who are also called clerics in law, and other Christian faithful who are also called laity.” In both groups there are those Christian faithful who, professing the evangelical counsels, are consecrated to God and so serve the Church’s saving mission.1
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.
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.”2
The Pope enjoys, by divine institution, “supreme, full, immediate, and universal power in the care of souls”3.
The Bishops, established by the Holy Spirit, succeed the apostles. They are “the visible source and foundation of unity in their own particular Churches”4.
Helped by the priests, their coworkers, 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.
“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”5.
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.
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”6.
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.7
