Paragraph 4. CHRIST’S FAITHFUL – HIERARCHY, LAITY, CONSECRATED LIFE

875
“How are they to believe in him of whom they have never heard? and how are
they to hear without a preacher? and how can men preach unless they are
sent?”³⁹⁰ No one – no individual and no community – can proclaim
the Gospel to himself: “Faith comes from what is heard.”³⁹¹
No one can give himself the mandate and the mission to proclaim the Gospel. the
one sent by the Lord does not speak and act on his own authority, but by virtue
of Christ’s authority; not as a member of the community, but speaking to it in
the name of Christ. No one can bestow grace on himself; it must be given and
offered. This fact presupposes ministers of grace, authorized and empowered by
Christ. From him, they receive the mission and faculty (“the sacred
power”) to act in persona Christi Capitis. the ministry in which Christ’s
emissaries do and give by God’s grace what they cannot do and give by their own
powers, is called a “sacrament” by the Church’s tradition. Indeed,
the ministry of the Church is conferred by a special sacrament.
