II. The Sacrament of Holy Orders in the Economy of Salvation

From The Catechism of the Catholic Church

It is the same priest, Christ
Jesus, whose sacred person his minister truly represents. Now the minister, by
reason of the sacerdotal consecration which he has received, is truly made like
to the high priest and possesses the authority to act in the power and place of
the person of Christ himself (virtute ac persona ipsius Christi).²⁴
Christ is the source of all priesthood: the priest of the old law was a figure
of Christ, and the priest of the new law acts in the person of
Christ.²⁵
